We are using HSRP for High availability option with two 3845 .
Two routers are having WAN links terminated in HWIC cards and we need to track these ports which are on ethernet.
As WAN is on ethernet , it do not go down and we can not be used by standby track interface command for HSRP priorty changeing.
So we are using interface track command , with ip sla and icmp echo configuration.
So we are monitoring next hop of the WAN link (ISP side ip address ) as target and our HWIC port as source IP address for ICMP-ECHO configuration in ip sla configuration.
But it is not working any experience please share.
Even if we could do static routing with distance that can be changed with inteface track commend it will solve our problem.
We will route the traffic to second router if first tracking result is down.
any link on cisco.com is highly appreciable.
