Re: The Cidr Report - 4byte ASN handling [ In reply to ]

as-plain is not the "standard" per se. Think of it more as
the "preferred" option within the industry.

o All major vendors support it, so there's no need
to convert to as-dot when you upgrade your router
software to support 4-byte ASN's.

o as-plain doesn't break your AS_PATH regular
expressions, which is very useful.

o as-plain is a known representation format among
operators, and 4-byte ASN's continuing this
tradition keeps the network stable.


as-dot notation looks really Cool & Sexy (tm), but is
cumbersome for your AS_PATH regular expressions. It doesn't
make things impossible, just, well, cumbersome :-).

Hope this helps.

Cheers,

Mark.
