RE: BGP AS-PATH PREPEND

Sorry, cut-paste issue, too many notepad open.

R1

!
router bgp 65500
 neighbor 10.255.0.26 route-map AS_CHANGE out
!
route-map AS_CHANGE permit 10
 match ip address OVER_L2
!
route-map AS_CHANGE permit 20
 set as-path prepend 65500 65500 65500
!
ip access-list extended OVER_L2
 permit ip host 10.100.60.11 host 10.20.80.11
!

It is still going over the other connection...

R1#traceroute 10.20.80.11
Type escape sequence to abort.
