Route ignored

Summary

The Routing Information Protocol version 2 (RIPv2) ignored the routes advertised by the neighbor.

Causes

The most common reasons for this error are:

• The route's network class is invalid.

• The route is to the loopback network.

• The route is to the broadcast network.

• The interface is configured to reject host routes and a host route was received.

• The interface is configured to reject default routes and a default route was received.

• A filter is configured on the interface which excluded the route that was received.

• The route contains invalid metric.

• The route contains some invalid information.

• Sample Event#1: IPRIPv2 is ignoring a route to %1 with next-hop %2 which was advertisedby a neighbor with IP address %3. The route''s network class is invalid.

• Sample Event#2: IPRIPv2 is ignoring a route to the loopback network %1 with next-hop %2which was advertised by a neighbor with IP address %3.

• Sample Event#3: IPRIPv2 is ignoring a route to the broadcast network %1 with next-hop %2which was advertised by a neighbor with IP address %3.

• Sample Event#4: IPRIPv2 is ignoring a host route to %1 with next-hop %2 which wasadvertised by a neighbor with IP address %3, because the interfaceon which the route was received is configured to reject host routes.

• Sample Event#5: IPRIPv2 is ignoring a default route with next-hop %2 which wasadvertised by a neighbor with IP address %3, because the interfaceon which the route was received is configured to reject default routes.

• Sample Event#6: IPRIPv2 is ignoring a route to %1 with next-hop %2 which was advertisedby a neighbor with IP address %3, because the interface on whichthe route was received has a filter configured which excluded this route.

• Sample Event#7: IPRIPv2 is ignoring a route on the local interface with IP address %1.The route is to the network %1 and it was received from a neighborwith IP address %2.The route is being ignored because it contains some invalid information.

• Sample Event#8: IPRIPv2 is ignoring a route to %1 with next-hop %2which was advertised by a neighbor with IP address %3,since the route was advertised with an invalid metric.The data is the metric.

Resolutions

• Verify the configuration on the interface and check whether it needs to be configured for accepting host or default routes.

• Verify the filter(s) configured on the interface.

• Verify the configuration on neighbor router(s) and make sure they generate valid routes.
