I'm seldom able to get specific, substantive criticisms from people who make comments like these, other than to say that the configuration language is not obvious and not well-documented (I agree, for now). Like any piece of software, gated does of course have some bugs in it, but I haven't seen evidence that it has more or more egregious bugs than other routing protocol implementations. And it gets a lot of things right that some people don't -- for example, it sends withdraws only for routes it has announced. I could go on, but I won't. The bugs are, of course, being worked on as they are found, just as with any other software. IMO gated's stability is pretty decent at this point. Likewise, it's missing some features, which are also being worked on. The proof of the pudding is of course in real-world use. As I assume most people on this list know, more than one large, respected backbone operator uses (or has used until recently) gated as their routing software, for quite some time. I've seen no evidence to suggest that gated is problematic for them; quite the contrary.

Two ASN 99s
by Bill Woodcock 17 Oct '96

17 Oct '96

This is probably a really stupid question, but why are there two ASN 99s? Was ASN 99 recycled or reassigned or something? I did a really quick uniq through the ASN list, and the only other duplicate registrations I see are more-specifics for ASNs which were assigned in blocks, 1381 and 3933, for example, but this doesn't seem to be such a case. Intel Corporation (ASN-INTEL) 99 University of Maryland (ASN-00) 99 Advanced Networks & Services Inc. (ASN-ANSBB-ASNNET-2-ASNBLOCK) 1381 Merit Computer Network Incorporated (ASN-NSFNETTEST46) 1381 NorthWestNet (ASN-NWNET-ASBLK1-ASNBLOCK) 3933 Oregon Department of Education (ASN-OPEN-NORTH) 3933 -Bill ________________________________________________________________________________ bill woodcock woody(a)zocalo.net woody(a)applelink.apple.com user(a)host.domain.com
