RSVP – Basic Config

1) Configure family mpls and enable the mpls protocol on the interfaces.

You have to enable the interface to accept labeled packets:

set interfaces ge‐0/0/0 unit 0 family mpls
set interfaces ae0 unit 0 family mpls

Next the interfaces should be specified under protocols mpls hierarchy. This way MPLS will know which interfaces it can use to forward traffic. You can use the option all to add all interfaces with family mpls. If the device has a dedicated management interface fxp0 it is good practice to disable it under protocols mpls.

set protocols mpls interface all
set protocols mpls interface fxp0.0 disable

Verify if the interfaces are enabled for MPLS.

2) Configure RSVP

Next you must enable RSVP on interfaces:

set protocols rsvp interface ge‐0/0/0.0
set protocols rsvp interface ae0.0

You can configure RSVP session authentication as well:

set protocols rsvp interface ge‐0/0/0.0 authentication‐key shnetkey
set protocols rsvp interface ae0.0 authentication‐key shnetkey

By default, the physical speed of the interface is used as RSVP interface bandwidth. To configure a different RSVP bandwidth value:

set protocols rsvp interface ge‐0/0/0.0 bandwidth 400m
set protocols rsvp interface ae0.0 bandwidth 400m

RSVP will install the routes in the inet.3 table. All LSP routes are installed in this table on the ingress node.
