R211x-HP Flexfabric 11900 MPLS Command Reference

107
After the device receives an RSVP message with an authentication object, it checks whether it has an
RSVP authentication neighbor that matches the IP address in PHOP of the message (Path or Path Tear
message) or matches the source IP address in the message (message other than Path and Path Tear). If
a matching neighbor exists and an authentication key has been configured for the neighbor, the device
verifies the validity of the message according to the key. Otherwise, the device uses the authentication
key configured in interface view or RSVP view to verify the message validity. If no authentication key is
configured in any view, the device ignores the authentication object carried in the message and accepts
the message.
When sending an RSVP message, the device checks whether it has a matching authentication neighbor
according to the next hop address for the destination address in the RSVP message. If a matching
neighbor exists and an authentication key has been configured for the neighbor, the device sets the
authentication object of the message according to the key. Otherwise, the device uses the authentication
key configured in interface view or RSVP view to set the authentication object. If no authentication key is
configured in any view, the device does not add an authentication object in the message.

# Create RSVP authentication neighbor 1.1.1.1, enter RSVP neighbor view, and configure a plaintext
authentication key abcdfegh for the neighbor.
