I've setup a GRE tunnel between 2 Cisco routers. I'd like to monitor one of the routers over the VPN tunnel, for bandwidth info. I've tried simply configuring snmp, which doesn't work. Having read up on the subject, it looks like I'll need to setup vrf routes. Would someone be able to provide me with some simple config on how I could setup SNMP monitoring of this router over the VPN tunnel?
Your help is much appreciated.
