Hi!
Since JunOS 9.1, Juniper supports 32-bit AS Numbers (RFC 4893), and release
notes states that:
<cite>
Support for 4-byte AS numbers is also extended to the AS extended-community
attribute and AS-path regular expressions
</cite>
but documentation on defining AS Path regular expressions does not provide
any examples using 32-byte asn's.
So, I'm just curious, how should they be formatted ?
For example, If I want to filter paths originated by Gert Doering's AS3.3,
should I set up filter as 'as-path as33 "3.3$", or it will be interpreted
by old rules as '<anything> 3 <any as> 3' and I need to use some other
syntax ?
PS: and, Gert, thanks for providing AS3.3, AS-SPACENET and route-object
with origin: AS3.3 for real-life testing :)
