I have this section lists error messages that appear in the router logs, and provides troubleshooting tips: “%FIB-3-FIBDISABLE : Fatal error, slot [#]: no memory and %FIB-3-NOMEM: Malloc Failure, disabling dCEF on line card”. What is this error means? Does have anyone experienced it? Please can you share some possible solution for this type of error. Thanks
Error appear in the router logs.
How many routes are exchanged in each direction for each peer? Ensure that the proper distinction is
made between routes and paths. Routes count the number of prefixes in the BGP routing information base. Paths count
the number of BGP prefixes advertised to a neighboring peer. For example, if five BGP peers send the full routing table,
then each peer is sending the same routes. Assuming the peers have 90 percent overlap in their routes,
then the receiving router has a route table of about 150,000 routes with five paths for most routes
Other factors to consider include the following:
There is an LC engine on the 12000 Series.
The number of Interior Gateway Protocol (IGP) routes.
The number of adjacencies.
Load balancing—The number of paths to the same destination.
Use of MPLS Virtual Private Network (VPN) and the number of Virtual Routing and Forwarding (VRF) instances and the number of routes per VRF.
