Troubleshooting Routers

6-14

If the attempts to ping fail, verify that you conﬁgured the router with the

correct IP network, interface, and subnet addresses.

Endstation Can Ping Local and Remote Interfaces on the Router, but Cannot Ping a

Remote Station

Do the following:

1. Ping the device on each link in the path between the source and

destination to determine the location of the problem.

2. Make sure that the “next hop” for each network points to the correct

interface.

3. Ping from the remote station to the local station.

This veriﬁes that each router in the path not only has a route to the remote

segment but also has a path back to the originator of the ping request.

Troubleshooting Routing Information Protocol (RIP)

If the router cannot reach a network or host, determine whether the entry is in the

routing table.

If the entry is in the routing table, determine whether the next hop and metric are

correct.

If the entry is not in the routing table, do the following:

1. Determine whether the router enabled RIP.

2. Set RIP Listen on the RIP interface.

3. Determine whether a RIP station on an attached network is sending RIP

packets.

4. Use Packet Capture or a network analyzer to capture the RIP packets

and verify the accuracy of the advertisements from other RIP stations.

Note: Use the Site Manager or Technician Interface “path” option when

pinging the remote station. This option provides the same functionality as

traceroute does on a UNIX workstation.
