B. MP-iBGP is needed to support 6PE.
C. LDP is needed to support 6PE.
D. P routers need to be dual stack.

QUESTION 356
Which three statements about 6VPE are true? (Choose three.)
A. An additional address family was added to MP-BGP to support 6VPE.
B. 6VPE routes are installed in the global routing table.
C. MP-BGP can be used to propagate routes between the PE and the CE.

Correct Answer: ACD
QUESTION 357
Which three options are restrictions for MPLS VPN BGP Local Convergence? (Choose three.)
A. The MPLS VPN BGP Local Convergence feature affects only traffic that is exiting the VPN. Therefore, it cannot fully protect traffic end-to-end by itself.
B. This link protection can be initiated during a HA SSO. But links that were configured with this protection before the switchover begins remain protected after the
switchover.
C. The MPLS VPN BGP Local Convergence feature for IPv4/IPV6 supports the eBGP, RIP, EIGRP,OSPF, and dynamic routing protocols.
D. Any next-hop core tunneling technology that is supported by BGP is also supported for protection, including MPLS, L2TPv3, and IP/GRE. CSC protocol
between the PE and CE is also supported. Interautonomous system option A (back-to-back VRF) is supported because it is essentially the same as performing
the PE-CE link protection in both autonomous systems. However, interautonomous system options B and C protection are not supported.
E. If you perform an in-service software downgrade from an image that does include this link protection to an image that does not support this feature, active
protection is halted when BGP routes are refreshed.
Correct Answer: ADE
