NEW QUESTION 15
An engineer is troubleshooting L3VPN traffic loss over the MPLS-enabled core network when new core links were enable. Assuming that the IGP is properly configured, which issue causes a temporary data flow blackholing when the IGP and LDP reconverges?

• A. MPLS-TE tunnels without LDP adjacencies are used over the new links black-holing the traffic before the LDP label exchange is completed
• B. MP-BGP sessions between PE and RR routers require extra time to reconverge than the underlying IGP
• C. IP packets are forwarded as soon as routes are learned over a new IGP adjancey before the label exchange happens over the new links
• D. LDP is a Layer 2 protocol forwarding Label packets before the IGP reconverged

NEW QUESTION 16
Which statement about multicast VPN is true?

• A. The MDT group address should be the same for both address families in the same VRF.
• B. The MDT group address should be the same for both address families in the different VRFs.
• C. Configuration of the MDT source on a pre-VRF basis is supported only on IPv6.
• D. The MDT group address should be different for both address families in the same VRF.

Answer: A

Explanation: Restrictions for Multicast VPN for Multicast Routing
· Configuration of the MDT source on a per-VRF basis is only supported on IPv4. · The MDT group address should be the same for both the address families in the same VRF. Default-MDTs must have the same group address for all VRFs that comprise a MVPN.
Data-MDTs may have the same group address if PIM-SSM is used. If PIM-SM is used, they must have a different group address, as providing the same one could result in the PE router receiving unwanted traffic. This is a PIM-SM protocol issue, not an implementation issue.
