Usage Guidelines

Usage Scenario

When configuring the VPLS to use tunnels for packet exchange, run the tnl-policy command.

Prerequisites

One of the following operations has been performed before this command is used:

The pwsignal bgp command and the route-distinguisher route-distinguisher command have been executed for Kompella VPLS.
The pwsignal ldp command and the vsi-id vsi-id command have been executed for Martini VPLS.
The bgp-ad command and the vpls-id vpls-id command have been executed for BGP AD VPLS.

Precautions

After the tnl-policy command is executed, the configured tunnel policy determines which tunnel between PE devices is preferred to forward traffic and whether load balancing is used. When creating a tunnel policy, specify the sequence of selecting tunnels. If no tunnel policy is configured, the default tunnel policy is used. That is, only LSP tunnels are selected and no load balancing is performed.

Example

# Configure the tunnel policy name for the VSI.
