mpls rsvp-te resv-rro

Function

The mpls rsvp-te resv-rro command configures record route objects (RROs) carried in Resv messages.

The undo mpls rsvp-te resv-rro command restores the default setting.

By default, the labels carried in the transit LSP RRO in turn are inbound interface address with upstream label, LSR ID with upstream label, and outbound interface address. The labels carried in the egress LSP RRO in turn are inbound interface address with upstream label, LSR ID with upstream label.

Format

mpls rsvp-te resv-rro transit { { incoming | incoming-with-label } | { routerid | routerid-with-label } | { outgoing | outgoing-with-label } } ^*

mpls rsvp-te resv-rro egress { { incoming | incoming-with-label } | { routerid | routerid-with-label } } ^*

Usage Guidelines

Usage Scenario

Two devices of different types must have the same RRO configuration to ensure that they can communicate with each other. You can run the mpls rsvp-te resv-rro command to configures RROs carried in Resv messages.

Precautions

The modification takes effect only for new LSPs.
