Configuring RSVP-TE resource reservation confirmation
Reservation confirmation is initiated by the receiver, which sends the Resv message with an object
requesting reservation confirmation.
Receiving the ResvConf message does not mean resource reservation is established. It only indicates that
resources are reserved on the farthest upstream node where the Resv message arrived and the resources
can be preempted.
To configure RSVP-TE resource reservation confirmation:

3. Enable resource reservation
confirmation.
mpls rsvp-te resvconfirm Disabled by default.
Configuring RSVP authentication
RSVP adopts hop-by-hop authentication to prevent fake resource reservation requests from occupying
network resources.
It requires that the interfaces at the two ends of a link must share the same authentication key to exchange
RSVP messages.

Do not configure both FRR and
RSVP authentication on the same
interface.
Configuring DSCP for outgoing RSVP packets
The DSCP in the ToS field of the IP header marks and determines the sending priority of the packet.
