What I'm trying to do is take two routers, "A" and "B" where 'A' is the primary router. Just like with active\passive firewalls and HSRP I want to "float" the default gateway between either Router A and Router B (22.214.171.124). All downstream hosts will use 126.96.36.199 as their DG.
Router A or Router B will need to advertise the 188.8.131.52/24 IP space, but I only want the 'active' router to be working at a given point in time. That means when A is active I don't want providers sending traffic through B. Router B, just like a passive firewall, needs to just sit there but still have the entire BGP routing table available and even likely advertise for a quick failover. I only want Router B to 'kick in' if Router A goes down. Will this work?
I may also host at IXPs.
The vendor doesn't really matter but you can assume Cisco if describing in config helps.
