Re: bgp as-path modification [7:38632]

[John Neiberger]

Here's one example:

router bgp 100
 neighbor 10.1.1.1 remote 200
 neighbor 10.1.1.1 route-map prepend out
!
access-list 1 permit 20.0.0.0
access-list 1 permit 30.0.0.0
!
route-map prepend permit 10
 match ip address 1
 set as-path prepend 100 100 100
!
route-map prepend permit 20
!

This will prepend AS100 three times when it's advertising 20/8 and 30/8
to this neighbor.

HTH,
John

does anyone have a sample config that uses a route-map
to modify the as path in bgp?

i can't seem to find an example.


thanks

You can try - 

BGP Statement - 
neighbor x.x.x.x route-map prepend out/in

Route-Map - 
route-map prepend permit 10
 set as-path prepend 701 701 701

We use this statement to make sure that we force traffic to come back our
"main" DS3...
