peer as-number (BGP multi-instance VPN instance IPv4 address family view) (group)

Function

The peer as-number command configures an AS number for a specified peer group.

The undo peer as-number command deletes the AS number of a specified peer group.

By default, no BGP peer is configured, and no AS number is specified for a peer group.

Format

peer group-name as-number as-number

undo peer group-name as-number

Parameters

Parameter	Description	Value
group-name	Specifies the name of a peer group.	The name is a string of 1 to 47 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
as-number	Specifies a destination AS number.	For an integral AS number, the value is an integer ranging from 1 to 4294967295. For an AS number in dotted notation, the value is in the format of x.y, where x and y are integers ranging from 1 to 65535 and from 0 to 65535, respectively.

Usage Guidelines

Usage Scenario

The peer as-number command is used to create a BGP peer.

Precautions

If a peer does not join any peer group or the peer group to which a peer belongs is not configured with an AS number, deleting the AS number of the peer will reset the peer relationship.

If a peer in a peer group is not configured with an AS number, deleting the AS number of the peer group will interrupt the connection on the peer.

The AS number for external session group cannot be the same as the local AS number.

Example

# Set the AS number to 200 for a peer group named test.
