Lab 10‐1: Packet Tracer ‐ RIP Lab - sthompson2752/Network-Fundamentals GitHub Wiki

This lab involved using Packet Tracer to utilize RIP routing in a series of networks.

Useful Instructions: Visualize the RIP occurring by going into simulation mode, clearing all filters, and adding RIP as the only filter in the simulation panel. Fast forward time and RIP packets will be seen moving across the networks. View RIP packet details by clicking on the desired packet in the simulation panel and going to "Inbound PDU details". You can tell what the destination is by looking at the top of the panel. It will say "PDU Information at Device: XX". The packet information is under "Rip v.1" and "Rip Route Packet". Use router 2811 and switch 2960. Use red timer cable. RIP is dynamic distance vector (networks that are added are the ones directly connected to each other). Dynamic routing uses protocols that make routers send routing table info to neighbors... benefit is automatic creation of tables, no manual. RIP is IGP (interior gateway protocol) because it works within an organization and carries info about internal infrastructure prefixes. Opposite is EGP (exterior gateway protocol) which is used to send info between organizations (most common is BGP border gateway protocol). EGP needed for scaling large network, define administrative boundary, and for policy. RIP being distance vector means the routers send broadcasts with their route table to and other routers will then update their tables, happens every 60 seconds (routing preference based on hops) Opposite of this is line state (more popular). Only keep-alives are send to neighbors and link state updates with changes.

Configuring RIPv2 on Cisco: 1. Open a router and navigate to the RIP routing section. This will automatically run the command "router rip" in the command prompt. 2. Navigate to the CLI and enter the command "version 2". This changes the RIP to RIPv2. 3. Use the command "network x.x.x.x" to add the necessary networks to the router. 4. To determine what networks to add, add any network that is directly connected to the router. 5. Double check that the commands worked by going to the RIP routing section under Config. The network addresses added should appear there. 6. Network addresses can also be added via the RIP routing section. Both ways do the same thing.

When adding the 10.10.10.0 and 10.10.20.0 networks to the routers for RIP, the routers kept adding the addresses as 10.0.0.0. I asked Professor Amy about this and she was not sure why that was happening. Although it was odd, all of the devices in the networks were still able to ping each other and all the appropriate networks appeared in the routing tables. No problems were caused other than some confusion on my part.
