Configuring AS4 Number Representations
Enable one type of AS number representation: ASPLAIN, ASDOT+, or ASDOT.
Term Description
ASPLAIN the method Dell Networking OS used for all previous Dell Networking OS versions.
It remains the default method with Dell Networking OS. With the ASPLAIN notation,
a 32–bit binary AS number is translated into a decimal value.
ASDOT+ representation splits the full binary 4-byte AS number into two words of 16 bits
separated by a decimal point (.): <high-order 16 bit value>.<low-order 16 bit value>.
ASDOT representation combines the ASPLAIN and ASDOT+ representations. AS numbers
less than 65536 appear in integer format (asplain); AS numbers equal to or greater
than 65536 appear using the decimal 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.
