Use the

ip-address
as-number
as-number
command. After that, the system creates the
specified peer by default.
z
Specify the AS number of the peer when adding it to the specified peer group by using the
peer
ip-address
group
group-name
as-number
as-number
command; or use the
peer as-number
command to specify the AS number of a peer group, and then a newly added peer will belong to
the AS.
The AS number of a peer/peer group cannot be modified directly. To do so, you have to delete the
peer/peer group and configure it again.

# In BGP-VPN instance view, specify peer group
test2
in AS 200 (the VPN has been created).
