mpls rsvp-te resv-rro egress

Function

The mpls rsvp-te resv-rro egress command specifies the contents of a Record Route Object (RRO) carried in a Resv message on Egress.

The undo mpls rsvp-te resv-rro egress command restores the default RRO contents.

By default, the RRO carried in a Resv message sent by an egress LSP contains the address of the inbound interface and the label allocated to the upstream LSR, and LSR ID and the label allocated to the upstream LSR.

Format

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

Usage Guidelines

Usage Scenario

When RSVP-TE is used to establish an MPLS TE tunnel, devices of different vendors cannot communicate because the sequence numbers of subobjects in RRO fields of Resv messages sent by these devices are inconsistent. The mpls rsvp-te resv-rro command can be used to adjust the sequence numbers of sub-objects in the RRO fields of Resv messages so that devices of different vendors can communicate.

This command can be used to specify the following contents of the RRO field in a Resv message:

Subobjects in the RRO field
Whether each subobject carries a label

Prerequisites

Enable MPLS RSVP-TE

Configuration Impact

After the configuration, the content and sequence of the RRO in the Resv message are affected.

Precautions

The mpls rsvp-te resv-rro egress command takes effect only for new LSPs, not existing LSPs.

Example

# Configure the RRO carried in a Resv message sent by a Egress LSP to contain the LSR ID and the label allocated to the upstream LSR, the address of the inbound interface, and the address of the outbound interface and the label allocated to the downstream LSR.
