Router Failover

Can one use a non multi access (WAN ) interface to address router high availability.

For example is there a way to run something like HSRP/VRRP over a Serial link?

Re: Router Failover

Routing do that for you.

For true redundancy you need to have more that one wan circuits, because the failure rate of them is much, much higher than the the router one.

So you end having multiple routers and wan circuits for true redundancy, and routing protocols make that possible for IP networking.
