  B. The adjacency database contains all the links between all the routers.

• Question 394:

  Which of the following best describes downstream on demand label distribution?

  A. An LSR answers requests for label mappings immediately, without waiting for a label mapping from the next-hop.
  B. An LSR advertises label mappings to all peers for which it might be a next-hop for a given FEC.
  C. An LSR distributes a label mapping for a FEC when it has been requested to do so.
  D. An LSR propagates a label mapping downstream for a FEC. only if it has a label mapping for the FEC's next-hop.

• Question 395:

  What must be configured before a SAP can be created on an E-pipe?

• Question 396:

  Assume that, on the Alcatel-Lucent 7750 SR, an LSP is configured with one-to-one FRR and node protection. Which of the following statements are FALSE? (Choose two)

  A. Each PLR signals a detour LSP that avoids the downstream node. If the downstream node cannot be avoided, a detour LSP that avoids the downstream link is signaled.
  B. The detour LSP can take one or more hops before merging back on the protected LSP.
  C. The merge point of the protected LSP must be the next-next-hop node
  D. 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.
  E. 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.
  C. The merge point of the protected LSP must be the next-next-hop node
  E. 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.

• Question 397:

  A. A Type 4 LSA is not generated in a single area AS.
  B. A Type 4 LSA is generated by the ABRs of the area that contains the ASBR.
  C. A Type 4 LSA advertises the external networks connected to the ASBR.
  D. A Type 4 LSA is not flooded in the area that contains the ASBR.

• Question 398:

  Click the exhibit. This output is from router R4. Service 333 is a VPLS. Why might the peer 10.10.10.1 have the same value for IngLbl and EgrLbl?

  A. The labels are of local significance only, so other routers can use the same value.
  B. 10.10.10.1 has yet to send its own unique label.
  C. Router R4 is using the same tunnel to send and receive to 10.10.10.1.
  D. The service on 10.10.10.1 is down, so it is rejecting packets.
  A. The labels are of local significance only, so other routers can use the same value.

• Question 399:
