• Question 451:

  Which of the following statements are TRUE regarding a fully meshed VPLS service with a default setting? (Choose 3)

  A. The vc-id on the mesh-sdp must be explicitly configured.

  B. The vc-id on the mesh-sdp is automatically assigned by a PE using the service id.

  C. The VPLS service id, on all PE routers, does not have to match.

  D. The VPLS service id, on all PE routers, must match.

  E. If dynamic signaling is required, the signaling on all PE routers must be set to TLDP in the configuration of the SDPs.

  F. The signaling on all PE routers will default to TLDP in the configuration of the SDPs; therefore, no configuration change is required for dynamic signaling.

  Correct Answer: ADF

  The link between routers R4 and R6 are configured with an admin group "red". What happens when the LSP is first signaled?

  A. The LSP will go through the path R1-R2-R4-R6.

  B. The LSP will go through the path R1-R3-R5-R6.

  C. The LSP is down because router R1 detects that no path can meet its constraints.

  D. The LSP is down because router R4 detects that no path can meet its constraints.

  Correct Answer: C

  All links are operationally up initially. When the link between routers R4 and R6 goes down, what will router R1 do?

  A. Router R1 will switch traffic to the secondary path immediately.

  B. Router R1 will discard traffic until a new IGP route to router R6 is re-calculated.

  C. Router R1 will discard traffic because the secondary path is not a fully strict path.
