BGP Four-Byte AS Numbers

The XCM8800 software supports 4-byte AS numbers, which can be entered and displayed in 
the ASPLAIN and ASDOT formats, which are described in RFC 5396, Textual Representation 
of Autonomous System (AS) Numbers.

When entering an AS number in a policy file, you must enter a 

unique 2-byte or 4-byte AS number. The transition AS number, AS 
23456, is not supported in policy files.

BGP Attributes

The following BGP attributes are supported by the switch:

Origin—Defines the origin of the route. Possible values are Interior Gateway Protocol 

(IGP), Exterior Gateway Protocol (EGP), and incomplete.

AS_Path—The list of ASs that are traversed for this route. The local AS-path is added to 

the BGP update packet after the policy is applied.

AS4_Path—This attribute is used by 4-byte peers when sending updates to 2-byte peers. 

This attribute carries AS-number information that can be represented only in 4-bytes.
