Release Information

Statement introduced before JUNOS Release 7.4.

Description

Specify the neighbor (peer) AS number.

The autonomous system (AS) numeric range in plain-number format has been extended in JUNOS Release 9.1 to provide BGP support for 4-byte AS numbers, as defined in RFC 4893, BGP Support for Four-octet AS Number Space.

Beginning with JUNOS Release 9.2, you can also configure a 4-byte AS number using the AS-dot notation format of two integer values joined by a period: <16-bit high-order value in decimal>.<16-bit low-order value in decimal>. For example, the 4-byte AS number of 65,546 in plain-number format is represented as 1.10 in the AS-dot notation format.

Options

autonomous-system—AS number.

Usage Guidelines

See Defining BGP Groups and Peers and Specifying the Peer’s AS Number.
