I have two ISP's and two routers running BGP between them peering to my AS.
Both routers peer with ISP routers and have an IBGP relationship between
them.
I put the following config into one router asuming my as is 1
route-map aspend permit 30
set as-path prepend 1 1 1 1 1 1 1 1
router bgp 1
neighbor x.x.x.x.remote-as 2
neighborx.x.x.x. route-map aspend out
This should append the as 1 and make it less perfered for traffic to come
into the link via the best path algorithm when making the decision which
route to choose from other AS's. We did this configuration and an hour
later on the internet we where unable to see our as prepends from any of the
looking glasses. How long in the real world will this update take to
propergate via the looking glasses?
