try EGP and you should be fine w/ 4byte ASNs.

Autonomous systems will be assigned 16-bit identification
numbers (in much the same ways as network and protocol numbers
are now assigned), and every EGP message header contains one word
for this number.
Was that a 36-bit word?

I think 3B2 code deserves its own place in hell. Poring over the
ESS#5 code, someone found that there were lots of strcmp(p, "f(")
== 0 checks (I may have gotten the exact string wrong but it's
close). It took us a while to figure out why. Apparently, location
0 on the 3b had the 3 bytes 'f' '(' '\0', someone noticed that when
programs blew up they were pointing to "f(", and the worlds most
amazing kludge for detecting nil pointers was born.

16-bit "word" in the sense of a PDP-11 or DG Nova, not 36-bit "word"
in the sense of a Univac-1100 or DECSYSTEM-20. Be glad that it wasn't
a 12-bit "word" in the sense of a PDP-8.
