Click the Exhibit button. Referring to the exhibit. PE-1 and PE-2 are getting route updates for VPN-B when neither of them service that VPN. Which two actions would optimize this process? (Choose two.)
A.
Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement on the PEs.
B.
Configure the family route-target statement on the RR.
C.
Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement on the RR.
D.
Configure the family route-target statement on the PEs.
BGP route target filtering can be configured on PE devices or on route reflectors (RRs). Configuring BGP route target filtering on RRs is more efficient and scalable, as it reduces the number of BGP sessions and updates between PE devices. To configure BGP route target filtering on RRs, the following steps are required:
Configure the family route-target statement under the BGP group or neighbor configuration on the RRs. This enables the exchange of the route-target address family between the RRs and their clients (PE devices). Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement under the routing-options configuration on the RRs. This enables the RRs to resolve next hops for VPN routes using the inet.0 routing table.
B,D route target filtering must be implemented on RRs and PEs. C is not relevant since this option is used when the PEs are not in the data path in order to resolve routes, and has nothing to do with route target filtering
C is not required, because "resolution rib bgp.l3vpn.0 resolution-ribs inet.0" is only required for RR's that are not on the LSP, in the diagram it shows it is on the LSP, hence can resolve next-hops as it has access to the inet.3 table.
The Route Target family needs to be on the PE's and the RR's
