(Optional) Setting RSVP Authentication Lifetime

(Optional) Setting RSVP Authentication Lifetime

The RSVP authentication lifetime is set to prevent RSVP authentication from being prolonged when CR-LSP flapping causes frequent re-establishment of RSVP neighbor relationships and repeatedly performed handshake.

Context

RSVP neighbors retain an RSVP neighbor relationship within a specified RSVP authentication lifetime even if there are no CR-LSPs between the RSVP neighbors. Configuring the RSVP authentication lifetime does not affect existing CR-LSPs.

Procedure

  • Configuring RSVP authentication lifetime in the interface view
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The view of an RSVP-enabled interface is displayed.

    3. Run mpls rsvp-te authentication lifetime lifetime

      The RSVP authentication lifetime is set.

    4. Run commit

      The configuration is committed.

  • Configuring RSVP authentication lifetime in the MPLS RSVP-TE peer view
    1. Run system-view

      The system view is displayed.

    2. Run mpls

      The MPLS view is displayed.

    3. Run mpls rsvp-te peer ip-address

      The MPLS RSVP-TE peer view is displayed.

      If ip-address is an interface IP address of the neighbor, not the neighbor LSR ID, key authentication will only take effect on that neighbor interface. Key authentication then provides high security and has the highest priority.

      If ip-address is a neighbor LSR ID, key authentication will take effect on all interfaces on the neighbor. Authentication configured using this method has a lower priority than that configured based on the neighbor's interface IP address but has a higher priority than that configured in the interface view.

    4. Run mpls rsvp-te authentication lifetime lifetime

      The RSVP authentication lifetime is set.

    5. Run commit

      The configuration is committed.
