Minimum MPLS RSVP example

Minimum configuration example for MPLS RSVP

MPLS RSVP must be enabled on interfaces before MPLS RSVP is supported.

This configuration example shows how to configure MPLS RSVP on the Head node with the vyatta@vm-mpls8-5# prompt, the Midpoint node with the vyatta@vm-mpls8-2# prompt, and the Tail node with the vyatta@vm-mpls8-7# prompt in the following topology:

Head --- Midpoint --- Tail

  1. Enter the following configuration commands for the Head node at the vyatta@vm-mpls8-5# prompt.
    
    set interfaces dataplane dp0p1s15 address 10.10.15.5/24
    set interfaces loopback lo address 5.5.5.5/32
    set protocols mpls-rsvp interfaces interface dp0p1s15
    set protocols mpls-rsvp tunnels tunnel t7 destination 7.7.7.7
    set protocols ospf area 0 network 5.5.5.5/32
    set protocols ospf area 0 network 10.10.15.0/24

  2. Enter the following command at the vyatta@vm-mpls8-5# prompt to verify the Head node configuration.
    
    vyatta@vm-mpls8-5# run show mpls rsvp session
