---------------
think of ...
"bgp best-path as-path ignore"
this case
if one of the letter steps is in favor of the ebgp path(i.e. origin code),
the locally generated path will be used, by step 3 of the decision process.
and
you can not prepend ibgp routes...

Subject: Re: bgp - prepending to locally source routes
I also added to my router "ip local policy route-map addas in an attempt to
get this to work but no success even though matches are made
R5# sh route-map addas
route-map addas, permit, sequence 10
Match clauses:
ip address (access-lists): 1
Set clauses:
as-path prepend 1234
Policy routing matches: 213 packets, 25679 bytes
I think the reason why I cannot prepend to sourced routes is because the
route goes directly to the Local-RIB .... because the route is not received
from any peer.
If my thinking is right, then my original comment is true :
"Choose the route originated locally rather that the one that is not" is
not needed because
as-path of a route originated locally will always be shorter than any route.
Any comment welcome...
Thanks,
Pierre-Alex
