We are upgrading our Wan infrastrucuture in a staged environment. We've got two providers an IP block and AS nubmers from both providers. Initially we ordered two 3825 edge routers, 1 for each provider, ATT and Optimum. Because of the handoff we got from ATT we had to put a 7200 router in front of one of the 3825 edge routers (see attachment). There is a switch between Router1 and Router2, Router2 and Router3 are directly connected. BGP and IBGP works between all of the routers both inbound and outbound. The problem I have is with HSRP. I've configured router2 as the active router in HSRP. The problem is, if that router goes down the Router1 still advertises the BGP routes and a host on the inside can't get in because it still sees the ATT side as the preferred path back in. I know there are a few ways solve this, looking for suggestions. Not sure if I can advertise BGP to the upstream router on the ATT side from Router2 or not. I could also plug and interface on router3 into the switch that router1 and router2 are in. BGP-IBGP-HSRP-InfrastructureSani.jpg
