Option: Configuring GMPLS Support for Unnumbered Links

The JUNOS Software supports RSVP traffic engineering over unnumbered interfaces. With this feature, you do not have to configure IP addresses for each interface participating in the RSVP-signaled network. Traffic engineering information about unnumbered links is carried in the IGP traffic engineering extensions for OSPF and IS-IS, as described in RFC 4203, OSPF Extensions in Support of Generalized Multi-Protocol Label Switching (GMPLS). Unnumbered links can also be specified in the MPLS traffic engineering signaling, as described in RFC 3477, Signaling Unnumbered Links in Resource ReSerVation Protocol - Traffic Engineering (RSVP-TE).

To configure RSVP for unnumbered interfaces, you must configure a router ID using the router-id statement specified at the [edit routing-options] hierarchy level. The router ID must be routable (you can typically use the loopback address). The RSVP control messages for the unnumbered links are sent using the router ID address (rather than a randomly selected address). To configure link protection and fast reroute on a router with unnumbered interfaces enabled, you must configure at least two addresses. In addition to the router ID, we recommend that you configure a secondary interface on the loopback:

[edit]routing-options {router-id address;}
