1.5 Configuring Tunnel Policies Applied to L2VPN

By default, the system selects LSPs for a VPN and no load balancing is carried out. If load
balancing or other types of tunnels are required, you need to configure a tunnel policy and bind
the tunnel policy to the tunnels.

1.5.1 Establishing the Configuration Task

Before configuring a select-sequence tunnel policy for an L2VPN, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you complete the configuration task quickly and accurately.
Applicable Environment
By default, LSPs are selected for a VPN, and no load balancing is carried out. To perform load
balancing or select tunnels of other types, configure and apply the corresponding tunnel policies.
For an L2VPN tunnel, the tunnel policy is applied to VC.
At present, a tunnel policy in select-sequence mode consists of the following parts:

Pre-configuration Tasks
Before configuring a tunnel policy, complete the following tasks:
