Usage Guidelines

Usage Scenario

By default, VPLS forwards packets over LDP LSPs on the public network, and load balancing is performed if there are more than one LDP LSP to the same destination address.

If you want to change the type of the public network tunnel used for packet forwarding or if you want to enable load balancing among multiple tunnels, you can run the tunnel-policy command in the system view to configure a tunnel policy and the tnl-policy command in the VSI view to reference this tunnel policy.

Prerequisites

The tunnel policy to be referenced has been created.

Configuration Impact

After a tunnel policy is referenced, the VPLS traffic is forwarded on the public network using the tunnel specified in the tunnel policy.
The undo tnl-policy command restores the default tunnel (LDP LSP) used for packet forwarding.

Precautions

In addition to running this command to reference a tunnel policy, you can run the peer command in the VSI view to specify the peer address and the tunnel policy to be referenced by the VSI. The tunnel policy specified in the peer command has a higher priority than that specified in the tnl-policy command in the VSI view. If tunnel policies are specified in both the tnl-policy and peer commands, the tunnel policy specified in the peer command is preferred.

# Configure a VSI to reference the tunnel policy named policy1.
