Task 5: Verify RIP Routing
Use the
show ip route
command to verify that each router has all the networks in the
topology entered in the routing table.
Step 1.
Routes learned through RIP are coded with an
R
in the routing table. If the tables are not
converged as shown here, troubleshoot your configuration. Did you verify that the config-
ured interfaces are active? Did you configure RIP correctly? Return to Task 3 and Task 4
to review the steps necessary to achieve convergence.

Use the
show ip protocols
command to view information about the routing processes.
Step 2.
The
show ip protocols
command can be used to view information about the routing
processes that are occurring on the router. This output can be used to verify most RIP
parameters to confirm the following:
RIP routing is configured.
■
The correct interfaces send and receive RIP updates.
■
The router advertises the correct networks.
■
RIP neighbors are sending updates.
