Configuring the IP-Prefix Tunnel Function

The IP-prefix tunnel function can be configured and used to establish P2P RSVP-TE tunnels in a batch, which simplifies the configuration.

Usage Scenario

When you want to create a large number of P2P RSVP-TE tunnels or create P2P RSVP-TE tunnels to form a full-mesh network, creating them one by one is laborious and complex. To simplify MPLS RSVP-TE tunnel configuration, configure the IP-prefix tunnel function so that P2P RSVP-TE tunnels can be established in a batch.

The full-mesh network indicates that a P2P RSVP-TE tunnel is established between any two nodes on a network.

Pre-configuration Tasks

Before configuring the ip-prefix tunnel function, complete the following tasks:

Configure an IGP to implement connectivity at the network layer.
Enable MPLS TE and RSVP-TE.
Configure IGP TE (OSPF or IS-IS).
(Optional) Configure TE attributes for links.

Configuring an IP Prefix List: An IP prefix list can be configured to define destination IP addresses used in the ip-prefix tunnel function.

(Optional) Configuring a P2P TE Tunnel Template: A P2P TE tunnel template can be configured, and MPLS TE tunnel attributes can be set in the template.

Using the Automatic Primary Tunnel Function to Establish P2P TE Tunnels in a Batch: The automatic primary tunnel function can be used to establish P2P TE tunnels in a batch.

Verifying the IP-Prefix Tunnel Function Configuration: After configuring the IP-prefix tunnel function, verify the tunnel information, including the tunnel status, a P2P TE tunnel template used to establish tunnels, and IP prefix list.
