Troubleshooting RIP
The most common problem found in RIP that prevents RIP routes from being advertised is discontiguous
subnets because RIP Version 1 does not support VLSM. First, make sure both Layer 1 and Layer 2 are
functioning. Then, use the commands reviewed in this exercise to verify and troubleshoot the network.
What command generates the following output?
