Hi
I have an small MPLS network with around 30 x ASR920, no P, all routers are PE. 2 of them are running as RR. All works fine.
My Public Internet is running in a VRF, so upstream just peers to a 920 and it sends prefixes to the RR that sends them out. RR are also forwarding traffic. Currently we have a filter on the upstrem BGP peering that filters all but prefixes that the upstream provider AS originates.
(WHY: We have a costumer that only revieves these, and uses us as a paid peering to the upstream providers net)
Now i am ading 2 x ASR9001 to the setup. Each upstream will be connected to a ASR9001. The 9001 will step in and act as a PE router. And in the final setup act as PE/RR.
MY goal is to have the 2 RR (New 9001) to send all routes (Full table) to each other. But when they send routes to the other PE (ASR920) they should then Internet VRF filter out all prefiexes that has my upstream AS number in AS-PATH.
Why: I whould like to have full table on the RR, and i have a costumer onboarding next month, and he needs full table. So my guess, is to let him peer directly with the RR (That has the full table) Like multihop BGP.
BUT how do i prevent the PE (9001 connected to the Internet) from sending all the prefixes (from the full Internet table) to the RR Clients connected to it. They should only have prefixes where my own AS number is in the list.
