Is their a way to remove the first AS number (not private) from an AS
For example we are receiving a route with AS PATH 123 456 457 458 and we
want to remove the 123 AS and put in the BGP table the route with AS 456
457 458 ?
The reason we want to do this is because we have customers connected to out netowrk via an MPLS service provider who has a public AS. We receive our customer routes (who may have their own BGP) with the AS number of the MPLS provider in the path (normal BGP behaviour) but we do not want and we are not allow to announce AS number of the provider to our Upstream.
Thanks for your reply
