Configuring and Applying a Tunnel Selector

Configuring and Applying a Tunnel Selector

Usage Scenario

In BGP/MPLS IP VPN networking, tunnel policies apply to VPN instances. All the routes of a VPN instance are iterated to the same tunnel. In inter-AS VPN Option B networking, the ASBR receives all VPNv4 routes from PE peers. The ASBR has these VPNv4 routes iterated to LSPs or, if bandwidth guarantee is required, MPLS TE tunnels. Without configuring VPN instances on ASBRs, tunnel policies cannot be configured on the ASBRs.

In inter-AS VPN Option C networking, a device cannot implement load balancing among BGP LSPs by default.

The tunnel selector is then introduced to address the problems.

The tunnel selector can apply tunnel policies to VPNv4 routes. The tunnel policies will select proper tunnels for the routes.

Pre-configuration Tasks

Before configuring a tunnel selector, complete the following tasks:

  • Configure a tunnel policy.
