If i have a /23 block and I have two isps and 2 different routers. I want
to perfer traffic to come into 1 router for the block opposed to the other.
From what I understand /24 is the highest mask that wont be summarized.

All traffic should come into router1 untill it is down then traffic will
come into router 2 because they have more specific routes correct?

Router1 most perfered
ip route x.x.x.x x.x.x.x (next hop) 0
ip route x.x.x.x x.x.x.x (next hop) 0
router bgp x
network x.x.xx.x 255.255.255.0
network x.x.x.x 255.255.255.0

Router2 less perfered
ip route x.x.x.x 255.255.254.0 (next hop) 0
router bgp x
network x.x.x.x 255.255.254.0
