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 protocols bgp group PE2 family inet6 unicast
B.
set interfaces ge-1/1/1.0 family mpls
C.
set protocols bgp group PE2 family inet6-vpn
D.
set protocols mpls ipv6-tunneling
Explanation:
Tunneling IPv6 Traffic over MPLS IPv4 Networks
D: You enable IPv6 tunneling by including the ipv6-tunneling statement in the configuration for the PE routers.A: BGP automatically runs its import policy even when copying routes from a primary routing table group to a
secondary routing table group. If IPv4 labeled routes arrive from a BGP session (for example, when you have
configured the labeled-unicast statement at the [edit protocols bgp family inet] hierarchy level on the PE router),
the BGP neighbor’s import policy also accepts IPv6 routes, since the neighbor’s import policy is run while doing
the copy operation to the inet6.3 routing table.
