Cisco Integrated Services Virtual Router
Known Affected Release
12.2SXJ
Description (partial)
None
Symptom:
A Cisco router running Next Hop Resolution Protocol (NHRP) over
Multipoint GRE (mGRE) tunnels may report the following error
upon receiving an NHRP Receive Resolution Reply packet:
%NHRP-3-PAKREPLY: Receive Resolution Reply packet with error
- insufficient resources(5)
Conditions:
The issue was earlier seen in CSCdt23105, where a Cisco router
running Next Hop Resolution Protocol (NHRP) will lookup a
destination prefix in the NHRP cache when forwarding a packet.
In the process switching path, NHRP will also try to lookup a
cache entry for the real destination prefix, instead of the
next-hop IP address for that prefix in its global routing table.
When NHRP performs such a lookup for a host prefix (/32), it
fails to find a match, even if a less specific network cache
entry does exist. This event results in the %NHRP-3-PAKREPLY
message being displayed to the console.
