I have 4 ISP links and I want to route certain traffic only to one ISP wouldn't weight work?
route-map WEIGHT per 10
match ip add 1
set weight 40000
route-map WEIGHT per 20
router bgp 65111
nei 188.8.131.52 remote-as 65112
nei 184.108.40.206 route-map WEIGHT in
Yes, using weight you can prefer the specific route from one ISP & That route will get installed in your routing table .
Note : It work with traffic orignated from inside to outside.
