If you have specified no AS number for a peer group, peers added to it can use their own AS
numbers.

test
as 100.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test as-number 100
# In BGP-VPN instance view, specify the AS number for peer group
test
as 100.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer test as-number 100
