Q. How does Frame Relay over MPLS work?
A. Traffic is encapsulated in MPLS packets and forwarded across the MPLS network. When encapsulating Frame Relay over MPLS, the Frame Relay header and the frame check sequence {FCS} are stripped from the packet. The bits for Backward Explicit Congestion Notification {BECN}, Forward Explicit Congestion Notification {FECN}, Discard Eligibility {DE} and Command/Response {C/R} are carried across the MPLS network in the "Control Word" header.

NEW QUESTION 20
Refer to the partial Cisco IOS XR PE router configuration exhibit for supporting a Layer 3 MPLS VPN customer using BGP as the CE-to-PE routing protocol.

• C. The 10.1.1.1 BGP neighbor has not been activated for IPv4 unicast routing.
• D. The 10.1.1.1 BGP neighbor has not been activated for the VPNv4 address family.

Answer: A

Explanation:
http://www.cisco.com/en/US/docs/ios/12_2sr/12_2sra/feature/guide/srbgprid.html Route Distinguisher
A router distinguisher {RD} creates routing and forwarding tables and specifies the default route distinguisher for a VPN. The RD is added to the beginning of an IPv4 prefix to change it into a globally unique VPN-IPv4 prefix. An RD can be composed in one of two ways: with an autonomous system number and an arbitrary number or with an IP address and an arbitrary number. You can enter an RD in either of these formats:
•Enter a 16-bit autonomous system number, a colon, and a 32-bit number. For example: 45000:3
•Enter a 32-bit IP address, a colon, and a 16-bit number. For example: 192.168.10.15:1
