Monitoring and Maintaining NHRP
To monitor the NHRP cache or traffic, use either of the following commands in EXEC mode:
The NHRP cache can contain static entries caused by statically configured addresses and dynamic
entries caused by the Cisco IOS software learning addresses from NHRP packets. To clear static entries,
use the no ip nhrp map command in interface configuration mode. To clear the NHRP cache of dynamic
entries, use the following command in EXEC mode:
In a dual hub Dynamic Multipoint VPN (DMVPN) environment, when using the clear ip nhrp command
on the hub, you may see the following error message on the spokes:
%NHRP-3-PAKERROR: Receive Error Indication for our Error Indication, code: protocol
generic error(7), offset: 0, data: 00 01 08 00 00 00 00 00 00 FF 00 44 5F F6 00 34
This is only an informational message generated as a part of the NHRP purge notification processing and
will not cause any other issues.
