Conguring AS4 Number Representations
Enable one type of AS number representation: ASPLAIN, ASDOT+, or ASDOT.
Term
Description
ASPLAIN
Default method for AS number representation. With the ASPLAIN notation, a 32–bit binary AS number is
translated into a decimal value.
ASDOT+ A 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 A 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.
