2. Once you isolate a problem router, determine whether routing is enabled on
the BSR. To view the routing table, enter the show ip route command in
Privileged EXEC mode, as shown in the following example:
RDN#show ip route
Examine the command output to see whether the routing table is populated
with routing information. If the command output displays no entries, the
routing information is not being exchanged.
3. If the routing information is not being exchanged, a routing interface may not
be configured.
4. To configure a routing interface, use the interface ethernet command, as
shown in the following example:
RDN(config)#interface ethernet 7/0
where:
7 is the SRM slot and 0 is the ethernet interface on the BSR 64000.
5. To set the IP address and subnet mask for a routing interface, use the ip
address command, as shown in the following example:
RDN(config-if)#ip address 10.10.10.92 255.255.255.0
Q Source quench.
P Protocol unreachable.
N Network unreachable.
U Port unreachable.
H Host unreachable.
Note: The BSR 1000 uses the same syntax, however the ethernet slot
and port are each set to zero.
