mpls rsvp-te authentication
Description
Use the
mpls rsvp-te
authentication
command to enable RSVP message authentication on the interface.
Use the
undo
mpls rsvp-te authentication
command to disable RSVP message authentication on the
interface.
The RSVP messages sent out of the interface convey a message authentication digest created using the
hash algorithm and the configured authentication key. This authentication key is also used by the interface
to authenticate received RSVP messages. For the two interfaces at the two ends of a link to exchange
RSVP messages, they must share the same authentication key.
This hop-by-hop authentication of RSVP is to prevent fake resource reservation requests from occupying
network resources.
The RSVP message authentication and Fast Reroute are mutually exclusive.
