Advertising the same static route via BGP on active / standby HSRP devices: Problem?
Posted on 2010-08-26
I have 2 6509s as in an HSRP pair (SW1 and SW2). They are iBGP peers and each has a connection to a pair of firewalls (FW1 and FW2). Only one firewall is active. I want to create a static route on SW1 and SW2 that points to the firewall to get to a certain network. And I want to redistribute that static route.
Currently, both SW1 and SW2 have static routes configured, but they are not redistributed. So I am going to redistribute the single static route using a route-map.
I am relatively new to BGP and I can't get my head around what is going to happen when I configure this. Assuming FW1 is active then the connection between FW2 and SW2 is dead, and this would mean that the static route would not be redistributed by the "standby" SW2. I don't have an easy way to lab this up. Can someone provide some insight?
