Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Label Request message
Why this is correct
The Label Request message is sent by an LSR to ask a neighbour for a label binding for a specific FEC. Label Mapping returns the binding, Label Withdraw removes it, and Label Release acknowledges it, so Label Request is the correct request type.
- ✗
Label Mapping message
Why it's wrong here
Label Mapping advertises a binding the sender has already allocated; it is the response, not the request. It is tempting because it carries the label information being sought, and it would be correct when a downstream LSR distributes a newly assigned label to its upstream neighbours.
- ✗
Label Withdraw message
Why it's wrong here
Label Withdraw tears down an existing binding, so it cannot solicit new ones; the neighbour already holds the label being removed. It is tempting because it is a request-type message, and it would be correct when a router needs to stop a neighbour advertising a specific FEC.
- ✗
Label Release message
Why it's wrong here
Label Release returns a previously received binding to the peer, freeing it; it never asks for bindings. It is tempting because it is sent toward the neighbour holding labels, and it would be correct when a router no longer needs a label previously advertised by that peer.
