we have hub and spoke topology (multipoint VPN). one of branch site has 2 Wan links; one primary gi0/0 and one secondary dialer0. At the moment tunnel source is gi0/0 and it works fine but during automatic failover tunnel drops because gi0/0 comes down. when i manually change it to tunnel source dialer 0, tunnel comes up again... whats the way to assign 2 interfaces as tunnel sources, one promary and the other secondary which work automatically during the failover?
int tunnel 0
ip add 10.0.0.1 255.255.255.0
tunnel source giga0/0
PLease advice
