Usage Guidelines

Usage Scenario

On a network with multiple autonomous systems (ASs), run the auto-discovery inter-as command to enable the auto-discovery function for inter-AS.

Prerequisites

The multicast function has been enabled in the VPN.

Precautions

After the auto-discovery inter-as command is deployed, the intra-AD routes and SPMSI-AD routes sent to BGP do not contain the no-export attribute, so that the routes can be sent to .inter-AS network to perform auto discovery.

Example

# Enable the inter-AS auto discovery function on a PE.
