259
Use undo peer group-name as-number to delete a peer group.

Syntax
peer { group-name | ip-address } as-number as-number
undo peer group-name as-number
undo peer ip-address
Default
No peer or peer group is specified.
Views
BGP view, BGP-VPN instance view
Default command level
2: System level
Parameters
group-name: Specifies the name of a peer group, a string of 1 to 47 characters.
ip-address: Specifies an IP address of a peer.
as-number: Specifies the AS number of the peer or peer group, in the range of 1 to 4294967295.
Usage guidelines
You can specify the AS number of a peer in either of the following ways:
• Use the peer ip-address as-number as-number command. After that, the system creates the
specified peer by default.
• 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. As an alternative, use the peer
as-number command to specify the AS number of a peer group so that a newly added peer
belongs 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.
Examples
# In BGP view, specify peer group test in AS 100.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test as-number 100
# In BGP-VPN instance view, specify peer group test2 in AS 200. (The VPN has been created.)
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family vpn-instance vpn1
[Sysname-bgp-ipv4-vpn1] peer test2 as-number 200
peer as-path-acl (BGP/BGP-VPN instance view)
Use peer as-path-acl to configure the filtering of routes incoming from or outgoing to a peer/peer group
based on a specified AS path ACL.
