D. The router uses MPLS Echo Request packets that are IP-routed,

A. The outer label TTL will be 251 and the inner label TTL will be 252.

B. The outer label TTL will be 251 and the inner label TTL will be 251.

C. The outer label TTL will be 249 and the inner label TTL will be 251.

A. The peer that generated the first Hello message.

B. The peer with the lower transport address.

C. The peer with the lower physical address.

D. The peer with the higher physical address.

E. The peer with the higher transport address.

A. The label recording desired flag must be set in the session attribute object in order for the PLR to know what label to swap when using the detour LSP.

B. The ingress router will set the local protection desired flag in the session attribute object of the path message to inform all routers along the protected LSP path to establish detour LSPs.

A. Link protection tunnels are established if a router is unable to establish node protection tunnels.

B. Link protection tunnels detour around a failed next downstream router.

C. Link protection tunnels can be created for both one-to-one or facility Fast Reroute.

A. Each PLR signals a bypass tunnel that avoids the next-hop downstream router.

B. The head-end router sets the local protection desired flag in the session attribute object.

C. No bypass tunnel is established if the PLR cannot provide node protection.

D. When a failure occurs, the PLR pushs an additional label onto the label stack.
