Checking the Local Routing Tables

Use the netstat -r command to display the local routing tables:

hostname# netstat -r 

The routing table looks like this:

Routing tables
 Destination     Gateway     Flags     Refcnt     Use      Interface
 host_a          sun-bb      UGH       0          0        ie1

Make sure there is a routing table entry for each possible destination network. In particular, Solstice X.25 devices, listed under Interface, should be matched with the appropriate host names listed under Gateway. The Gateway entry should, in turn, be matched with the correct entry under Destination.

If there is not a routing table entry for each possible destination network, and you are using static routing, add the appropriate static routes. If you are using dynamic routing with in.routed, do the following:

1. Check that in.routed is running by typing:

   # ps -ef | grep route root process_id 1 80 Feb 22 1:55 /usr/sbin/in.routed -q

   If the routing tables still are not correct, become superuser, and continue with the next steps.

2. Kill in.routed and flush the routing tables:

   #kill -9 process_id #/usr/sbin route -f

   where process_ID is the process ID displayed by the ps -ef command.

3. Restart in.routed as follows:

   #/usr/sbin/in.routed
