Is there any way to monitor DMVPN tunnel. I have a DMVPN tunnel configured but the problem is even if the internet link is down, the tunnel does show UP. I initially tested by using keepalives but the tunnel used to go down even if it up. Later a cisco article read that keepalives be used only on point to point gre tunnels and not dmvpn tunnels. Appreciate your suggestions.
Actually, i want to monitor in such a way that if the tunnel goes down, i can proactively know it by an alert in our remote monitoring tools. Currently our monitoring tool is not able to detect the tunnel because the tunnel interface does not go down ... as a work around, we have implemented a new point-point gre tunnel just for monitoring .. and we testing it wo be working fine ... but if the no. of sites are huge, this is a cumbersome solution. We would like to know if there are any other feasible alternatives than this. Thanks again.
Two ideas that come to mind, although whether they might work easily would depend much on you monitoring tool.
First, you might be able to SNMP poll NHRP on the hub and watch the far side tunnel addresses. (If this could be done, monitoring would work best if it "remembered" the NHRP address cache, watching for lost addresses.)
Second, you could define SLA to remote addresses and watch them.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
