2: System level 

group-name: Name of a peer group, a string of 1 to 47 characters. 

ip-address: IP address of a peer. 

as-number: AS number of the peer or peer group, in the range 1 to 65535. 

Use the peer as-number command to specify a peer/peer group with an AS number.  

Use the undo peer as-number command to delete a peer group. 

Use the undo peer command to delete a peer. 

By default, no peer or peer group is specified. 

You can specify the AS number of a peer in either of the following two ways:  

z 

Use the peer  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.
