hello mohammad,

you can just do a normal standby track command on both the serial interfaces

interface ethernet0

ip address 10.1.1.1 255.255.255.0

standby ip 10.1.1.3

standby priority 110

standby track serial0

standby track serial1

Refer to the following URL for more info:

Hope this helps. rate replies if found useful.

I knew the above configs for sure, but I dont want the second router to become the active one when one of the serials on the first router goes down ...only when both interfaces are down the second router becomes the active

If the priority of the Standby router us the default value of 100, then the following config will only drop the active router priority below 100 when both serial interfaces are down:

interface ethernet0

ip address 10.1.1.1 255.255.255.0

standby 1 ip 10.1.1.3

standby 1 priority 120

standby 1 preempt

standby 1 track serial0 15

standby 1 track serial1 15

Rgds,

Ian
