Helping students develop considerable skills of configuring routers for operation with RIP dynamic routing protocol.
- Specify IP addresses for all interfaces on all routers. Use addresses from different classful networks for the user networks in A and B routers, but in a way so that the prefix used is smaller than the class one (mask length is greater).
- Switch on RIPv1 on all routers. Find out about which prefixes routers A and B receive updates.
- Change the version of RIP from the first to the second one on all routers. Find out about which prefixes routers A and B receive information now.
- Perform the traffic capturing between the routers and find out which routing updates are appearing between the devices and when it's happening.
- Add loopback interface to router A and redistribute its prefix to RIP. Check how and when these changes will be visible in the network.
- Shutdown loopback interface on router A and find out what changes are happening in the RIP topology.
- Modify the network scheme in a way so that the router A could be disconnected from the network and router R1 would determine it only once the timers have been expired.
- Switch router A back on and check how the data are transferred between router A and router B once the network has been converged. Think up a more effective route (in your opinion) between A and B. Make up a situation in which the route you proposed would perform worse that the one chosen by RIP.
- Create two loopback interfaces on router B and assign /24 networks to them. Make sure that they are redistributed into RIP. Ensure that router A has a route for these networks. Adjust the prefix filtration on router A in a way so that only one of these two routes would get in the routing table.
- Make router B send the route to the default network. Make sure that router A receives it.
- Try to redistribute the static route to the super network that has a mask shorter than the class one. Make sure that such route redistribution doesn't function.
- Adjust RIP in a way so that the data between A and B would be transferred along the route A-R1-R3-R2-B, not A-R1-R2-B. Remember that in this case the network connectivity would subsist even if channel R1-R2 is unavailable. Think up several ways of dealing with this problem.
