Configure AS4 Number Representations
Enable one type of AS Number Representation: ASPLAIN, ASDOT+, or ASDOT.
• ASPLAIN is the method Dell Networking OS has used for all previous Dell networking OS versions.
It remains the default method with Dell Networking OS 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 in conjunction with the 4-Byte AS
Numbers feature. If 4-Byte AS Numbers are not implemented, only ASPLAIN representation is supported.
