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.
