H12-261_V3.0-ENU Exam Question 102

Which of the following descriptions are true about the establishment process of LDP LSP? (Multiple Choice)

A.The process of establishing an LSP is actually the process of binding the FEC to the label and advertising the binding to the upstream LSR of the LSP.

B.When the network topology changes cause the next hop neighbor to change, the LSR can directly reestablish the LSP by using the label sent by the original non-optimal next hop neighbor.

C.By default, the LSR is for the same FEC. The received label mapping can only come from the optimal next hop. It cannot be from the non-optimal next hop.

D.In the label publishing DoD mode, for a specific FEC, the LSR does not need to obtain the label request message from the upstream to perform label distribution and distribution.
