Use the prepend as-path.
Note that local-as prepends the local-as to external and internal updates.
If it is used on an AS that is a private AS, it prepents the local-as to the
private as to external BGP peers. This is probably a bug, because the
external AS doesn't/can't srip off the embedded private AS from the as-path
string.

I want to do that just for a specific route, this will mark all routes to
that neighbour
Is that possible?

Yes you can use the local-as command. For instance
Straight for the CD
The remote can peer with the neighbor 172.20.1.1 in AS 300 even though
the AS is set for 109
router bgp 109
network 172.20.0.0
neighbor 172.20.1.1 local-as 300

It's clear and easy to set BGP as-path prepend, and to add some AS
numbers for the outgoing updates - but my question is:
Is it possible to "cheat" and change AS-path so the neighboring peer
will see specific network as originated from completely another AS?
If yes - how?
Thanks
