Usage Guidelines

Usage Scenario

A tunnel interface name is used as a tunnel name by default, for example, Tunnel1. Alternatively, if you want to customize a name for a TE tunnel, the mpls te signalled tunnel-name command can be used to configure a TE tunnel name. For example, a TE tunnel from LSR A to LSR C is named LSRAtoLSRC.

Prerequisites

MPLS TE has been enabled using the mpls te command.

Precautions

A TE tunnel name must be unique on an entire device.

If a TE tunnel name is specified, RSVP signaling messages will carry the specified name. If a configured TE tunnel name is deleted or no TE tunnel name is specified, RSVP signaling messages will carry the TE tunnel interface name as the TE tunnel name.

The mpls te signalled tunnel-name command or its undo form takes effect on a TE tunnel established using only RSVP signaling, not a static route.

Example

# Name a TE tunnel LSRAtoLSRC.
