LAB1 Jerome Cardenas CCNA2

In this lab, we were required to set up a topology in packet tracer, that was presented on the board. The topology consisted of three routers, four switches, and twelve hosts in total. We first needed to get all the devices that we needed. We were told to use 2811 routers and 2950 switches. The hosts I used were all desktops. Afterwards, I put in all the necessary modules in the routers in order to set it up as its supposed to. I used four WIC-2T in order to have plenty of serial ports. I also put one NM-ESW-161 which provides us with 16 switching ports in each router. Here is a screenshot of the fully functional network.

I also configured each router in order to have the correct path to send packets. For each interface, I used the CLI in order to configure the correct path of the packets. For example, for the branch  router, I used the commands:

enable

config t

int s0/0/0

ip address 1.1.1.1 255.255.255.252

no shutdown

exit

This was used in order to configure the interface s0/0/0 which leads to s0/0/1. 

Here is the screen shot for each router's port view.

As you can see, in the screen shots, I configured each interface that was connected to each router. I configured each fast ethernet and serial that connected to branch and remote. However for HQ, I just needed to configure Serial interfaces, because there was no other interface that was connected to it. For HQ, I also set the clock rate to 64000.

The following is the routing table for each router:

HQ#show ip route

Packet Tracer Exploration: Ch4 - Packet tracer Skills Integration Challenge

This activity focused on subnetting skills, basic device configuration, and static routing. In this lab I learned how to design and document an addressing scheme thats based on the requirements. I learned how to pick out appropriate equipment, then cabled the devices. I Configured the static and default routing. I then learned how to verify full connectivity between all devices in the topology. First I designed an addressing scheme. First I placed four 2621XM in the network topology. I then connected all of the routers to 2621XM. I then renamed each router and it's hostname: [B1; B2; B3; B4]. I then connected switches to each router. Each router has 4 switches. I configured each switch to the subnet. I then configured all the routers to R1. I then tested the end-to-end connectivity. I used the ping command to do this. Each router pinged all other router interfaces and the web server. I used extended pings to test LAN connectivity to the web server. I then used verification commands to make sure that my configurations are complete.

Packet Tracer Exploration: Routing Loops

First of all, in this lab, all the routers have already been configured. All I am left to do is to identify the conditions leading to a routing loop and the implications on the router performance. I first examined branch1's configuration using the show run command. Then I located the static route command which is ip route 0.0.0.0 0.0.0.0 serial 0/. I did the same thing to examine branch2's configuration except to locate the static route command, i used the command ip route 0.0.0.0 0.0.0 serial 0/0. I tried to verify the connectivity from PC2 to PC0 using the ping command. The ping command was not successful and the packets failed to reach the destination. I reconfigured the routes by first clearing the current static route configuration. I did this by using the no ip route command. on both branch1 and branch2. I then re-configured the routers so that they can properly connect to each other. I then verified their connectivity again by using the ping command from PC2 to PC0, and it turns out my configuration was successful.

Packet Tracer Exploration: Ch3 - Packet Tracer Skills Integration Challenge

This packet tracer is an overview of the entire chapter and previous packet tracers that I had completed in the past.  First I designed an addressing scheme, then documented it. I then needed to select equipment and cable devices that were necessary for the network. I then connected the network together. Afterwards, I was able to apply basic configuration to each device in the network.  After that, then I configured static and default routing. Once that was done, I was able to test the connectivity of the devices to make sure that each device was configured properly. I used commands such as ping.  Oi then examined the configuration to make sure my configurations are complete.

Packet Tracer Exploration: Subnetting Scenario 3

In this lab, i was given the network address 192.168.1.0/24 to subnet and provide the IP addressing for then network shown in the topology diagram. First I examined the Network Requirements. I then Designed an IP addressing scheme by subnetting the 192.168.1.0/24 network into the appropriate number of subnets. In this packet tracer activity, I was able to determine the number of subnets that are needed. I then determined the number of hosts needed, and learned how to design the number of hosts needed. I then learned how to conduct research to find a solution

Packet Tracer Exploration: Subnetting Scenario 2

First I examined the network requirements. I then Designed an IP addressing scheme by subnetting the 172.16.0.0 network into the appropriate number of subnets. I needed to allow for the maximum number of hosts which was required for the largest subnet. I assigned the subnets to the network from the topology diagram. I assigned IP addresses to the Network Devices. First I assigned am address to the HQ router, then an address to the west router. I then assigned addresses to the East router, then addresses to the Branch1 router. Then I assigned addresses to the Branch 2 router, then assigned addresses to the Branch 3 router. I then assigned addresses to the Branch 4 router. Then I assigned addresses to the host PCs/ In the final task, I tested the Network Design. by applying my addressing scheme to the packet tracer file. I then Checked to see that all devices connected networks can ping each other and they were successful. In this packet tracer activity, I learned how to determine the number of subnets needed. I then determined the number of hosts needed. I then designed an appropriate addressing cheme. I then learned how to assign addresses and subnet mask pairs to device interfaces and hosts. I then examined the use of the available network address space. I then determined how static routing could be applied to the network.

Packet Tracer Exploration Subnetting Scenario 1

First I examined the network requirements. I then designed the IP addressing scheme by first subnetting the 192.168.9.9 network into the appropriate number of subnets. I then Assigned the subnets to the network shown in the Topology Diagram. In the third task, I assigned the IP address to the Network Devices, by first assign addresses to the HQ router. I then Assigned addresses to the BRANCH1 router also to the BRANCH2 router. I then assigned addresses to the host PCs. Lastly, i tested the Network Design. In this Packet Tracer activity, i determined the number of subnets needed. I determined the number of hosts needed. I designed an appropriate addressing scheme. I also assigned addresses and subnet mask pairs to device interfaces and hosts. I then Examined the use of the available network address space. I lastly, learned how to determine how static routing could be applied to the network.

Packet Tracer Exploration: Viewing Routing Table Information

In this packet tracer activity, I used the show ip route command so i can see details of routing table entries. All i needed to do was show the contents of the routing tables, since all routers have been configured. I used a version of the show ip command so I can see the details of routing table entries. In this packet tracer activity, I was able to review how to read and identify various things in the routing tables.

Packet Tracer Exploration: Convergence

In this packet tracer, I viewed the routing table of a converged network. I added a new Local area network to the topology. I learned how to view the debugging output. I finally watched the process of the network converging. First, I viewed the routing table for Routing table for Router2 and router 3. I then Documented the networks i learned from RIP. I then added a new LAN to the network topology by first adding a new 2960 switch and host to Router3. I Cabled the Switch from Fa0/1 interface to Router3's Fa0/1 interface. I then cabled the host to the fa0/2 interface on the switch.I then configured the appropriate IP addresses from the 12.0.0.0/8 addressing scheme for this LAN. I then Enabled the Fa0/1 interface on Router 3. I then Determined if the network has converged. I then turned on debugging on both routers. Afterwards, I was required to advertise the newly added network. THen I turned debugging off on router 2. I checked to see if the network has converged. In this lab, i learned how network converging works and how to actually set it up like that

Packet Tracer Exploration: Characteristics of IGP and EGP Routing Protocols

In this activity, i configured the default route from AS2 and AS3 (two different companies to the ISP (AS1) to simulate the Exterior Gateway Routing that would take place from both companies to the ISP. I then configured a static route from the ISP to AS2 and AS3 to simulate the exterior gateway routing that would take place from the ISP to its 2 customers AS2 and AS3. I looked at the routing table before and after both static routes and default routes were added so that i can observe how the routing table has changed. I verified the connections of each routers by checking to see if ping tests works. they did, and this packet tracer was successful.

Packet Tracer Exploration: Configure Ethernet Interfaces for IP on Hosts and routers

I used the packet tracer to practice configuring interfaces. Follow the additional instructions provided in the activity to examine the ARP process in simulation mode. First I configured IP information on Ethernet interfaces in a network. I then Configured the IP information on the PCs. I then Configured the IP information on router Ethernet interfaces. I was required to verify proper operation. I also verified the status on the bus routers, then the connectivity between hosts and routers. I went into simulation mode and observed the ARP operation. In this packet tracer activity, I practiced configuring PC's and Router Ethernet Interfaces. I then verified everything I did to make sure they were correct.

Packet Tracer Exploration: Build the Chapter Topology

In this packet tracer, I added all the necessary devices and connect them with the correct cabling. In this packet tracer, I first placed the devices on the topology. I then configured them accordingly. I added all the modules to the routers. I then named the devices in order to keep track of them and so that everything can be organized in the network. I then connected the devices. I connected the routers to each other using serial DCE. I also connected the devices to each other using straight through cables. I also used straight through cables in order to connect the LANs properly. In this activity, I learned how to place devices, configure them, rename them, then cable them.

Packet Tracer Exploration: Challenge Router Configuration

In this packet tracer activity, I designed and applied an IP addressing scheme for the topology show in the Topology Diagram. I allocated one class C network that i needed to subnet in order to provide a logical addressing scheme for the network. I cabled the network all together appropriately. Once the network is cabled, I configured each device with its appropriate basic configuration commands. The routers were then ready for interface address configuration according to the IP addressing scheme. When the configuration is complete, I used IOS commands to verify that the network is working properly. In this activity, I learned to subnet an address with the space it gave me. I was able to assign appropriate addresses to interfaces and document. I reviewed how to cable the network and perform basic configuration tasks on a router. I learned to configure and activate serial and FastEthernet interfaces. I then tested and verified all my configurations.

Packet Tracer Exploration: Basic Router Configuration

In this packet tracer, we were doing some basic router configuration. First I cabled the network. I connected each cable to its appropriate device. I then erased and reloaded the routers by: First I established a terminal session to router R1. I entered privileged EXEC mode. In order to clear the configuration, I issued the erase startup-config command. Once the prompt returned, I issued the reload commands. I repeated these steps on router 2 to remove the startup configurations, that could still be there. After I did all of that, I was able to apply basic configuration for router 1. It included disabling the DNS lookup with the no ip domain-lookup command. I then configured the passwords for EXEC, console password, and the virtual terminal lines. I configured the FastEthernet0/0 interface with the IP: 192.168.1.1/24. I then also configured the serial interface for the router. I then did the same thing to router 2. After doing all that, I tested the connectivity between Router R1 and R2. by ping commands. In this activity, I reviewed how to cable a network according to the topology diagram. I learned how to erase the startup configuration and reload a router to the default state. I then learned how to perform basic configuration tasks on a router. I was able to configure and activate Ethernet interfaces. THen Tested and verified configurations.

Packet Tracer Exploration: Cabling a Network with Routers, Switches, and Hosts

In this Packet Tracer lab, I reviewed the previously learned skills, including basic IOS command line interface operation and configuration commands. I also learned to save configuration files to a text files and to a TFTP server. Essentially, this is an overview of all the past labs combined, in order to help us prepare for the future labs. First I Cabled the Ethernet Links of the Network. I connected the R1 Router to the S1 Swith. I then connected PC1 to the S1 Switch. I then COnnected PC2 to the R2 Router. Afterwards, I cabled the Serial link between the R1 and R2 Routers. I established a console connection to the R1 Router. I then needed to Erase and Reload the Routers. I applied Basic configuration of router R1, most of them by using the CLI tab. I then applied Basic Configuration of Router R2. I configured the IP addressing on the Host PCs. I made the router show commands like show running-config, then show startup-config, then show interfaces, then show version. I Used ping command to test the connectivity between the R1 Router and PC1. I then used Traceroute command at the R1 privileged EXEC prompt so that i can see the path in which the packet will take from T1 router to Pc1. I then create a start.txt File. Then I loaded that file into the R1 router. In this lab, i reviewed the previous learned skills. I learned the basic IOS command line interface operation. I then Learned Basic router configuration. I also learned how to verify and test configurations, and the management of configuration files.

Packet Tracer Exploration: Equal Cost Load Balancing

In this packet tracer, all devices on the network and included and are already configured. I examined the equal cost load balancing. First I Viewed routing table information for R1. To do that , i accessed the CLI tab in order to see the routing table. I used the "show ip route". I saw an entry of the available routes from PC 1 to PC 2 by going through R1. I went into Simulation mode to examine the packets. I pressed auto capture/play button so I can see how the packets travel throughout this network, more specifically, through this routing table. With this, I was able to examine the equal cost load balancing.

Packet Tracer Exploration: Determine Best Path Using Routing Tables

In this Packet Tracer activity, I determined the best path using the routing tables. First I viewed the routing table information for R2. To that, I Accessed the CLI tab from R2. I typed in the command show ip route, so that i can view the routing table. I then proceeded to examine the routing table information for R2. With this routing table, I found out which was the best path in which the packets would be sent.

Packet Tracer Exploration: Routing Table Principles

In this packet tracer activity, I investigated a fully-converged network with connected, static, and dynamic routing. Packets are forwarded through the network on a hop-by-hop basis. I also learned that each router makes an independent forwarding decision based upon the router's knowledge of destination paths. I found out that a router makes  decisions based on the information in the routing table. The fact that one router has a complete routing table does not mean other routers have the same information. Routing information about a path from one network to another does not provide routing information about the reverse or return path.

Packet Tracer Exploration: Dynamic Routing

In this Packet Tracer Activity, i learned how the IOS installs and removes dynamic routes. First I configured the RIP on R2. I then configured RIP on R3. I then Configured RIP on R4. I then needed to verify the static and dynamic routes. First i Verified the routing tables on each router. I then examined the routing table on R1. I then Pinged from R3 to PC1. I entered a static route on R2 to reach R1's LAN. I configured a static route on R2, then I examined the routing table on R2. I Pinged R3 to PC1. In this activity, i learned that networks can use both dynamic and static routes, by seeing how they work together, and how to configure them.

Packet Tracer Exploration: Static Routing

In this packet tracer, i learned how the IOS installs and removes static routes. First I configured the static route on R3 using the CLI tab. I typed in the passwords and commands in order to access the ip route. However, the routing table shows directly connected routes, but there are no static routes to remote networks in the routing table. I then configured the terminal. I then examined the routing table on R3. Afterwards, I pinged R3 to PC1 in the CLI tab using the command "ping 192.168.1.10" The ping was not successful because there was no route on R1 to reach R3. I put in a static route on R1 to reach R3. I Configured the static route using the CLI tab. I examined the routing table on R1 from the CLI. I then Pinged from Router 3 to PC1. This activity helped me learn about how static routing worked, and how we can use The routing table to our advantage in networking.
