I have been testing with a small setup and have found no issues so far.
I run a few ASN32 boxes of which one with a 32bit AS. There's one
non-ASN32 box. It seems NEW_AS_PATH and NEW_AGGREGATOR_AS work fine and
cause no issues for the older quagga. Tested this for both IPv4 and
I'll also test all this (again) for MRT dumps, but I think that
everything on the Quagga side is really fixed (until the specification
is changed, but the changes I proposed are trivial to change for Quagga).
Once all my other software for RIS is done I'll install a new Quagga
on one of our machines, where it will carry several full tables and
hopefully a couple of ASN32 routes.
Actually, I've already hooked up one asn32 capable quagga to "the real
thing" yesterday for a short time:
rrc99# sh ip bgp 220.127.116.11/24
BGP routing table entry for 18.104.22.168/24
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
12654 16215 3549 4637 1221 2.2
22.214.171.124 from 126.96.36.199 (188.8.131.52)
Origin IGP, localpref 100, valid, external, best
Last update: Tue Jan 16 16:37:30 2007
So NEW_AS_PATH works nicely across many different asn16 routers.
Is anyone else also planning to test this? My use of quagga is most
likely not what most others would. I assume testing an asn32 capable
quagga with a 16bit AS would already be helpful, no need to get a new AS

One interesting question: what are other network equipment vendors doing
now? (and which of them are working on asn32 at all)

I forsee a whois client wrapper that translates 3.3333 to
large_number in that case ;-)

Should supports for other formats be removed once a decision has been
