Our ISP hands us an ethernet link. ISP router has one address of (for argument sake) 126.96.36.199/30 net, - let's say they have 188.8.131.52 we have the other usable address of 184.108.40.206/30 assigned to our 3825 router. Is it possible to use hsrp or vrrp if there is not two valid/unique "wan" IPs to assign to our routers? For example, if we had a pair of 3825 routers? are we stuck with basically a manual failover or requesting our isp to provide a larger address wan block ?
any feedback appreciated!
someone else had same question at :
