IP Routing—Configuring RIP, OSPF, BGP, and PBR
Troubleshooting Routing
View the running-config for the interface that connects to the peer that is not
receiving routes. If the send version does not match that implemented by the
peer, you must change it:
ProCurve(config-ppp 1)# ip rip send version [1 | 2]
If the interface is not transmitting any RIP messages, it may be configured as
a passive interface: it listens for updates but does not send them. View the
running-config and look for this RIP configuration:
passive-interface <interface ID>
If the interface should be sending RIP updates, use the no form of the
command to remove the configuration. From the RIP configuration mode
context, enter:
Syntax: no passive-interface <interface ID>
Sometimes you do not want to enable RIP on a network; however, other
routers still need to reach that network. In this case, make sure that you have
redistributed connected routes into RIP.
If you cannot find any of these problems on the local router, troubleshoot the
remote router.

Troubleshooting OSPF

When an OSPF router does not receive the correct LSAs, it cannot route traffic
correctly.
Because you can configure various routers to send and receive various LSAs,
depending on their role in the network, it is easy to inadvertently prevent a
router from receiving the LSAs it should.
You can use the enable mode debug commands to monitor OSPF activity in
detail and to view the LSAs that the router's interfaces send and receive. (See
Table 13-23.)
C a u t i o n
OSPF is a chatty protocol and the debug messages can be very processor-
intensive.
