hi all, i read somewhere that we can use manual next hop modification in BGP instead of using next-hop-self command, how can we do that ?
You would apply a route-map outbound on an iBGP neighbor as follow:
router bgp xx
neighbor x.x.x.x remote-as xx
neighbor x.x.x.x update-source lo0
neighbor x.x.x.x route-map set-nh out
route-map set-nh permit 10
set ip next-hop
