Verifying Reachability of All Hosts in the RIP Network

By using the traceroute tool on each loopback address in the network, verify that all
Purpose
hosts in the RIP network are reachable from each Services Router.

Click Start. Output appears on a separate page.
The final hop in the list is the host you want to reach.
The number of expected hops to the host matches the number of hops in the
traceroute output. The appearance of more hops than expected in the output
indicates that a network segment is likely not reachable.
