Usage Guidelines

Usage Scenario

During network transfer or service identification, a device needs to be simulated as multiple BGP devices logically. In this case, you can run the as-number command to configure an AS number for each VPN instance.

After the as-number command is used:
  • BGP peer relationships in the VPN instance are established by using the configured AS number.
  • The configured AS number is used to generate the aggregator attribute during route aggregation.
  • When advertising routes to an EBGP peer, the local device carries the AS number configured in the VPN instance.


If a BGP peer or a BGP peer group is configured in the VPN instance, you need to delete the configuration of the BGP peer or BGP peer group before configuring or deleting an AS number.


A VPN instance configured with an AS number cannot be configured with BGP confederation. Conversely, a VPN instance configured with BGP confederation cannot be configured with an AS number.

The AS number configured in the BGP-VPN instance view cannot be the same as the AS number configured in the BGP view.


# Set the AS number of the VPN instance named vpna to 65001.
