method (asdot+). For example, the AS number 65526 appears as 65526 and the AS number 65546
appears as 1.10.
NOTE: The ASDOT and ASDOT+ representations are supported only with the 4-Byte AS numbers feature. If you do not
implement 4-Byte AS numbers, only ASPLAIN representation is supported.
Only one form of AS number representation is supported at a time. You cannot combine the types of representations within an
AS.
To configure AS4 number representations, use the following commands.
Enable ASPLAIN AS Number representation.
CONFIG-ROUTER-BGP mode
bgp asnotation asplain
NOTE: ASPLAIN is the default method used to represent AS numbers and does not appear in the configuration display.
Enable ASDOT AS Number representation.
CONFIG-ROUTER-BGP mode
bgp asnotation asdot
Enable ASDOT+ AS Number representation.
CONFIG-ROUTER-BGP mode
bgp asnotation asdot+
