A.PE1 sends the data packet with three labels: the bottom label is a service label, the middle label is a BGP label, and the top label is an LDP label.

B.ASBR1 sends the data packet with one label: the BGP label.

C.ASBR1 sends the data packet with one label: the service label.

D.ASBR2 sends the data packet with three labels: the bottom label is a service label, the middle label is a BGP label, and the top label is an LDP label.

A.PE1 and PE2 advertise the same VPN route to the route reflector.

B.The route reflector receives two routes for prefix 10.1.1.0/24; one from PE1 and one from PE2.

C.The route reflector reflects two routes for prefix 10.1.1.0/24.

D.PE3 receives two routes and is able to load balance traffic across PE1 and PE2.

A.Logical Partitioning of route reflectors is simple and scalable, but requires more hardware.

B.Filtering at route reflectors requires either inbound filtering at the route reflector or outbound filtering at the PE routers.

C.Filtering at route reflectors allows the route reflector to filter routes received from PEs and only accept routes with a certain route distinguisher.

D.Logical Partitioning of route reflectors works best when PEs are partitioned to support different VPRNs.

A.Sap 1/1/1 create

B.Neighbor 192.168.1.2

C.Sap 1/1/1 customer 10 create

D.No shutdown

A.The ORF configuration must be done under the BGP neighbor context only.

B.When sending is enabled, the ORF function takes the route target list configured in all outbound policies and pushes this list to the peer by default.

C.When configuring ORF, the session with the peer must be cleared/reset for the new capability negotiation to take place.

D.When Outbound Route Filtering is configured, both the sending and acceptance of ORF are enabled by default.
