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 the Dell Networking OS version 8.2.1.0 and later. 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.
