Customer is connected to two ISPs and is advertising out 3 networks. I want to set it up so network A prefers isp y and network B and C prefer isp y. I did the following
neighbor isp x route-map as-path-ispy out
access-list 20 permit network A
route-map as-path-ispy permit 10
match ip address 20
set as-path prepend 1400 1400 1400
like logic for other provider
It did not do what I thought at all. Is setting as-path only for all routes and can't be done on a route by route basis?
