NEW QUESTION 4
Which statement about implementing the Cisco IPv6 provider Edge Router over MPLS is true?

• A. 6PE feature is supported over tunnels other than RSVP-TE tunnels.
• B. Core MPLS routers are supporting IPv6 only.
• C. 6PE feature is not supported over tunnels other than RSVP-TE tunnels.
• D. Core MPLS routers are supporting IPv4 only.

Answer: C

Explanation: ReferencE. http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6- over_mpls.pdf
The following restrictions apply when implementing the IPv6 Provider Edge Router over MPLS (6PE) feature:
Core MPLS routers are supporting MPLS and IPv4 only, so they cannot forward or create any IPv6 Internet Control Message Protocol (ICMP) messages.
Load balancing ability is not provided by Cisco 6PE between an MPLS path and an IPv6 path. If both are available, the MPLS path is always preferred. Load balancing between two MPLS paths is possible. BGP multipath is not supported for Cisco 6PE routes. If two BGP peers advertise the same prefix with an equal cost, Cisco 6PE will use the last route to cross the MPLS core.
6PE feature is not supported over tunnels other than RSVP-TE tunnels.
