I'm looking for a way to manipulate the default gateway based on source. I have 2 public IP ranges and I'd like range 184.108.40.206 to route through rt1 and range 220.127.116.11 to route through rt2. A default route 0.0.0.0 from rt1/isp1 is advertised to rt2 for failover in the event of a rt1/isp1 failure. This provides failover of the 18.104.22.168 network to route through isp2.
When traffic from 22.214.171.124 hits rt2 I'd like it to be routed out isp2 as long as that path is available. When the path is not available it should route to rt1.
HSRP for 126.96.36.199 points to rt1 primarily and hsrp for 188.8.131.52 pointing to rt2 primarily. iBGP and EIGRP are running between the routers.
What is the best way to send the 184.108.40.206 traffic out via isp2? (Currenly there's a default route from rt1 sending it to isp1) I'm sure I can use an ACL matching 220.127.116.11, route-map and set-next-hop but I'm not sure how to account for an isp2 failover? Track something on the isp2 side?
I ended up configuring a route-map for the 18.104.22.168 network and applying the set-next-hop based on a tracked IP on the ISP2 side. It looks like it should work but I'm having an issue when testing. One of the peers to ISP2 (there are 2 for some reason) terminates once I shut down the ISP2 link. The route-map on RT1 is as follows.
