The constraint in my case is the MPLS product I can buy. Each resilient access is configured as its own private AS for BGP. The core AS uses the SP registered AS. I have no option but to have a route table full of <private as>.<sp mpls as>.<private as> I have no option to impose a single consistent AS on my Supplier- and realistically only the one supplier for size of network I need in my market (Full national coverage of the uk). As it happens we do have our own registered AS we use for our internet facing presence and a limited number of external peerings. But again I have to jump through hoops to present all routes as that single AS after all no-one wants to see which SP I use for my MPLS core or how many private AS I have. Given I can change/amend/delete/add almost every other metric in the BGP decision process it seems strange I dont have full control to manipulate the AS path aswell. still life would be dull if it was all easy.
