I've configured an IP SLA and Event Manager to bring up a backup interface when the primary goes down. I have a ping to 188.8.131.52 for the IP SLA and when I shut the primary interface which, has a DMVPN to the Main site, the Event Manager is triggered and the secondary interface brings up the DMVPN with the Main site and all is good. When I try a different test where I cannot ping 184.108.40.206 but, the primary interface stays up(which is what will probably happen in the realworld) the Event manager is again triggered but the secondary interface never creates the tunnel back to the Main site. Both interfaces are configured with ip address dhcp and the default route is ip route 0.0.0.0 0.0.0.0 dhcp so, I'm wondering if this is my problem. When the primary is up, the secondary is down but, when the secondary is up I need the primary to also be up to continuosly ping 220.127.116.11.
I need this primary interface to stay up so it can continuosly ping 18.104.22.168 and trigger the Event manager again when it is successful.
I actually have it working at the moment but there is wierd going on. When I fail over to the backup interface(another DSL provider) by unplugging the voice cable to the primary DSL modem(that way, the g0/0-primary interface stays up and retains it's address), the pings are not stable. Is the router getting confused because interface g0/0 is still up. I can send more config.
