Usage Guidelines

Usage Scenario

A tunnel interface name is used as a tunnel name by default, for example, Tunnel 10. Alternatively, 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.

Configuration Impact

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.

Precautions

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

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

Example

# Name a TE tunnel LSRAtoLSRC.
