Endstation Can Ping Local and Remote Interfaces on the Router, but

Cannot Ping a Remote Station

If the endstation can ping the local and remote router interfaces but cannot ping a

remote station, do the following:

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

destination to determine the location of the problem.

Make sure that the next hop for each network points to the correct

interface.

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 RIP

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

for the network or host 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:

Determine whether the router enabled RIP.

Set RIP Listen on the RIP interface.

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

packets.

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 the UNIX

traceroute

command.
