mpls te path

Use mpls te path to specify a path for the tunnel and set the preference of the path.

Use undo mpls te path to delete the specified path.

Syntax

mpls te path preference value { dynamic | explicit-path path-name }

undo mpls te path preference value

Default

MPLS TE uses the dynamically calculated path to establish a CRLSP.

Views

Tunnel interface view

Predefined user roles

network-admin

Parameters

preference value: Set a preference value for the specified path, in the range of 1 to 10. The smaller the

value, the higher the preference.

dynamic: Uses the dynamically calculated path to establish the CRLSP.

explicit-path path-name: Uses the specified explicit path to establish the CRLSP. The path-name argument

specifies the name of an explicit path, a case-sensitive string of 1 to 31 characters.

Usage guidelines

You can specify up to 10 paths for a tunnel interface. The paths must have different preferences.

When establishing a CRLSP, MPLS TE performs CSPF calculations according to the specified paths in the

preference order from high to low until the CRLSP is established successfully. If the CSPF calculations for

all paths are failed, the CRLSP cannot be established.

Examples

# Configure that interface Tunnel0 can use explicit path path1 and the dynamically calculated path to

establish a CRLSP, and set a higher preference for the explicit path.
