The following description of the LDPLSP establishment process is correct?
- A. The process of establishing a LSP is actually to bind the FEC to the tag and advertise this binding to the LSP upstream LSR process.
- B. When a network topology change causes the next hop neighbor to change, the free label keep method is used. LSR can quickly rebuild the LSP by directly using the labels sent by the original non-optimal next-hop neighbor. Liberal needs more memory and tag space.
