Which of the following VPRN topologies must a customer implement to allow a given VRF to include routes from different VPRNs? What are the two primary problems the service provider must consider when providing traditional Layer 3 VPN services using only a single common routing table in the provider core? (Choose two) VPN-IPv4 addressing is made unique by defining an address structure consisting of: Choose the best answer to describe the result of the configuration of an Alcatel-Lucent 7750 SR shown below? Which of the following protocols are supported by the Alcatel-Lucent 7750 SR for the creation of transport tunnels within an autonomous system?

You are configuring spoke SDP termination of a VPLS service on a VPRN interface on an AlcatelLucent 7750 SR. The spoke SDP is running over a NULL encapsulated network port. The best practice is to set the VPRN interface p-mtu equal to what value over a NULL encapsulated network port. What are the main functions of a Layer 3 VPN? (Choose three). Based on the VPRN BGP decision process, which of the following routes is selected first if the command "PE1>config>service>vprn> bgp best-path-selection as-path-ignore" is executed? A service provider core consists of 6 PE and 4 P routers. Assuming route reflection is not used, how many internal BGP sessions are required in the service provider network for a correct operation of VPRN services?
