Products

• CA Spectrum
• CA eHealth

Issue/Introduction

For some of our devices, Spectrum DMVPN discovery is not creating the topology and connections.

Environment

Release : 10.4.1

Component : Spectrum Core / SpectroSERVER

Cause

VRF Context querying is not implemented for DMVPN device discoveries.   

Resolution

Spectrum will create the DmvpnNhrpApp model based on nhrpServerInternetworkAddrType (1.3.6.1.2.1.71.1.3.1.1.2)

 

It will also use nhrpServerInternetworkAddr (1.3.6.1.2.1.71.1.3.1.1.2) and nhrpServerNhcInternetworkAddr (1.3.6.1.2.1.71.1.3.3.1.4) to gather information related to Hub and Spoke.

 

Can you check if the status of the NHRP MIB on the non-working device by running the below command:

 

show snmp mib nhrp status
