RSVP Configuration Guidelines

To configure the Resource Reservation Protocol (RSVP), you include the rsvp statement:

protocols {

    rsvp {

        disable;

        graceful-deletion-timeout seconds;

        graceful-restart {

            disable;

            helper-disable;

            maximum-helper-recovery-time seconds;

            maximum-helper-restart-time seconds;

        }

        interface interface-name {

            disable; 

            (aggregate | no-aggregate); 

            authentication-key key; 

            bandwidth bps;

            hello-interval seconds;

            link-protection { 

                disable;

                bandwidth bps;

                bypass bypass-name {

                    bandwidth bps;

                    hop-limit number;

                    path address <strict | loose>;

                    priority setup-priority reservation-priority;

                    to address;

                }

                class-of-service cos-value;

                hop-limit number;

                max-bypasses number;

                no-node-protection;

                optimize-timer seconds;

                path address <strict | loose>;

                subscription percent;

            }

            (reliable | no-reliable);

            subscription percentage {

                ct0 percentage;

                ct1 percentage;

                ct2 percentage;

                ct3 percentage;

            }

            update-threshold percentage;

        }

        keep-multiplier number;

        load-balance {

            bandwidth;

        }

        peer-interface peer-interface-name {

            (aggregate | no-aggregate);

            authentication-key key;

            disable;

            hello-interval seconds;

            (reliable | no-reliable);

        }

        preemption {

            (aggressive | disabled | normal);

            soft-preemption {

                cleanup-timer seconds;

            }

        }

        refresh-time seconds; 

        traceoptions {

            file filename <replace> <size size> <files number> <no-stamp>

                <(world-readable | no-world-readable)>; 

            flag flag <flag-modifier> <disable>; 

        }

    }

}

You can include this statement at the following hierarchy levels:

• [edit protocols]
• [edit logical-routers logical-router-name protocols]

By default, RSVP is disabled.
