You are connecting your OSPF router to your customer's RIP router and redistributing the customer's routes into your OSPF domain. Your OSPF route is part of an NSSA and the ABR is injecting an OSPF default route, which you have advertised to your customer. After committing the configuration, you notice a routing loop between your OSPF router and the customer's RIP router.
Which action must you perform on your OSPF router to solve this problem?

• A.Convert the area to a stub area.
• B.Set the customer-facing interface to passive.
• C.Change the OSPF external route preference.
• D.Enable Type 7-to-Type 5 LSA conversion.

ISP 1 wants to configure an IPv6 L3VPN over its IPv4-only MPLS network for Customer-A.
PE1 has been configured as shown in the exhibit; however, IPv6 routes are not being passed between PE1 and PE2 in the Customer-A VPN.
In this scenario, which two commands are necessary on PE1 to enable IPv6 connectivity between CE1 and CE2? (Choose two.)

• A.set interfaces ge-1/1/1.0 family mpls
• B.set protocols bgp group PE2 family inet6 unicast
• C.set protocols mpls ipv6-tunneling
• D.set protocols bgp group PE2 family inet6-vpn

You are asked to implement an LDP-signaled VPLS network for a new customer. Which two statements are correct regarding this implementation? (Choose two.)

• A.The PE router advertises a label for each remote PE configured.
• B.A full mesh of LDP sessions between PEs must be configured.
• C.The same NLRI as Layer 2 VPNs is used.
• D.The PE routers distribute VPLS to label mapping using MP-IBGP.

What are two characteristics of L3VPNs? (Choose two.)

• A.Multiprotocol BGP is required for L3VPNs to function correctly.
• B.The IPv4 NLRI is required for L3 VPNs to function correctly.
• C.Matching route targets are required for L3VPNs to function correctly.
• D.Matching route distinguishers are required for L3VPNs to function correctly.

You are working with a new MPLS network that is using the default EXP classifier and default schedules. A small amount of traffic is being placed in the assured forwarding class.
No other traffic is passing through the network at this time.
In this scenario, what happens to the traffic that is being placed in the assured forwarding class?

• A.The traffic remains in the assured forwarding class and is dropped.
• B.The traffic is reclassified to the best effort forwarding class and is forwarded.
• C.The traffic is reclassified to the network control forwarding class and is forwarded.
• D.The traffic remains in the assured forwarding class and is forwarded.
