3. Determine if you are running RIP on the local and remote Routers. Use the config show command
on each Router to see if the start rip and ifconfig iface rip active commands are present in the
configuration, or issue the rip status command to determine if any RIP packets have been
transmitted or received by the Routers. If RIP is enabled in either or both Routers, temporarily
disable RIP by entering the stop rip and ifconfig iface rip off commands.
Enter the route -f command to flush the routing table of all routes learned by RIP. Do this on both
Routers if necessary. If you changed any RIP configuration try issuing the ping command again. Wait
approximately 45 to 60 seconds and try it a second time. If the remote and local nodes are now able
to communicate, there is a routing problem caused by RIP. If you are unsure of how RIP should be
configured, call Technical Support. If the local and remote nodes are still unable to communicate,
continue below.
4. Determine if RIP is running on the local and remote nodes. If so, try disabling it and flushing the
routing tables on the local and remote nodes of all routing table entries learned by RIP. See the
system administration manual for your system to determine how this should be done. After disabling
RIP and flushing the routing tables, try issuing the ping command again. Wait approximately 45 to 60
seconds and try it a second time. lf the remote and local nodes are now able to communicate, there is
a routing problem caused by RIP. lf you are unsure of how RIP should be configured, call Technical
Support.
To configure routing on the local node, add one of these three types of routes to the local node’s
routing table:
• host route to the remote node
• subnetwork route to the remote (sub)network to which the remote node belongs
• default route
For a host route, the destination address should be designated as the IP address of the remote node.
The next hop or gateway should be specified as the IP address of the local Router. The subnet mask, if
supported, should be specified as 255.255.255.255 or 32 bits.
For a (sub)network route, the destination address should be specified as the (sub)network number of
the remote node. The next hop or gateway should be specified as the IP address of the local Router. The
subnet mask, if supported, should be specified as the subnet mask or corresponding number of
significant contiguous bits of the remote (sub)network.
For a default route, the next hop or gateway should be specified as the IP address of the local Router.
To configure routing on the remote node, add one of the following three types of routes to the remote
node’s routing table:
• host route to the local node
• subnetwork route to the remote (sub)network to which the local node belongs
• default route
For a host route, the destination address should be designated as the IP address of the local node. The
next hop or gateway should be specified as the IP address of the remote Router. The subnet mask, if
supported, should be specified as 255.255.255.255 or 32 bits.
For a (sub)network route, the destination address should be specified as the (sub)network number of
the local node. The next hop or gateway should be specified as the IP address of the remote Router. The
subnet mask, if supported, should be specified as the mask or corresponding number of significant
contiguous bits of the local (sub)network.
