 Hi All,

Thanks for all the inputs. I do have some questions in regard to Route-Filtering pertaining to Route Reflectors configurations in an MPLS VPN environment. Assuming the following scenario -

Now while using Extended community based filtering by means of the ORF for route filtering. My question is as follows -

1. In a partitioned RR setup, should all the RR clients and RR server have the extended community list and bgp-rr group configured on them, in order to facilitate both outbound and inbound filtering (dynamic).

Assuming I have 2 RR's, each servicing a set of VPN's. Now in a situation in which an existing PE router suddenly needs to service a VPN, to which it has not provided routes previously, I understand that we would need to have the PE router establish an additional session to the other Route-reflector, which is currently reflecting routes to its clients for the particular VPN. This requires filtering to happen at the PE, wherein the PE should not spill over unwanted VPN routes to either of the RR's. Now while using Extended community based filtering by means of the ORF for route filtering. My question is as follows -

1. How would the same work here? Any sample config will be greatly appreciated.

Thanks in advance,

Tony.
