group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer
group must have been created.

Usage guidelines
Private AS numbers are typically used in test networks, and need not be transmitted in public networks.
The range of private AS numbers is from 64512 to 65535.
After you execute the command, you can get the following results:
If the AS_PATH attribute of a BGP update carries only private AS numbers, the device removes the
•
AS numbers before sending the update to the EBGP peer or peer group.
If the AS_PATH attribute carries both public and private AS numbers, the command does not take
•
effect. The device sends the BGP update to the EBGP peer or peer group without removing the
private AS numbers.
• If the AS_PATH attribute carries AS numbers of the peer or peer group, the command does not take
effect. The device sends the BGP update to the peer or peer group without removing the private AS
numbers.
This command is only applicable to an EBGP peer or peer group.
