I've recently enabled the IOS-XE NHRP MIB on an ASR-1001X and I'm wondering what common OID's people are using to monitor the status of their DMVPN tunnels. I'd like to use UnDP as a method of directly polling for NHRP OID's and then create alerts based on the values returned. Ideas so far are:
- In a dual hub environment, if the NHS changes to the secondary, a change in this OID value would trigger an alert email
- Unresolved next hop clients (if a spoke site can't get a resolution for another spoke site)
The MIB can be reviewed here and appears to be closely tied to RFC2677:
ftp://ftp.cisco.com/pub/mibs/v2/NHRP-MIB.my
However I ended up looking over the SNMP MIB explorer for search term "NHRP" and found most if not all of the related OID's:
http://snmp.cloudapps.cisco.com/Support/SNMP/do/SearchOID.do?objectNameValue=NHRP&objectDescriptionValue=&searchMode=exa…
All the OID's I've attempted to poll from so far have come back with a return of the OID not being supported or not returning a value. Does anyone have any OID's that actually work in this MIB, or any ideas on how to get a UnDP to work correctly with it?
