Backup dialer

hi

I have a remote site with two serial interfaces back to corporate. I need to setup a backup dialer. Is it possible to configure the back up dialer to kick in only when both the circuits are down

thanks

I would do it without using the backup interface feature. Use floating statics:

ip route (corportate address) serial0

ip route (corportate address) serial1

ip route (ip address of corporate dialer interface) 255.255.255.255 dialer1

ip route (corportate address) (ip address of corporate dialer interface) 200

As long as either serial line is up, no traffic will be sent to the dialer interace.

If you are using a routing protocol, skip the first two static routes and make sure that the static to the corporate network via the dialer interface has a higher administrative distance than that of your routing protocol.
