The routing problem which began to affect us at the end of November has returned. We are not receiving routes from milnet. Originally, the problem existed intermittently for about two weeks. After installing a new gated which provided a larger max packet size for egp the problem went away. The problem reappeared sometime last night after a three week period during which we believed the problem was resolved. Is anyone else who upgraded to the lastest gated still seeing this problem? Did something change on milnet yesterday? I have notified the NOC, but I would like to know if we are unique or if others are seeing these problems. ---Craig hunt@enh.nbs.gov (301)975-3827

The routing problem which began to affect us at the end of
November has returned. We are not receiving routes from milnet.
Please return a note with some specific information, including the list of
'core' or 'trusted' gateways with which you run EGP, and your own gateway
addresses. What operating system and release version are you running?
Are you running a version or port of unix to which the following message
refers? I think Bruce Cole is talking about a unix based on 4.2BSD.
The latest gated (I have one which is newer than version 1.3.1.36), when run
in 4.3BSD, makes use of the sendsockopt(2) option SO_SNDBUF and SO_RCVBUF to
enable receipt and sending of large packets.

Subject: EGP Broken?
In addition to insuring that your EGP routing daemon can handle packet sizes
larger than 2048, Unix sites need to adjust their kernel to handle the larger
size. In net/raw_cb.h, redefine RAWSNDQ & RAWRCVQ to be something like 4096.
With that change I am now able to receive routing updates from the butterflies
which are longer than 2048 bytes.

Apologies to those of you who have already seen this on egp-people or
gated-people. Also, thanks to Bruce for this other info, and I hope he is not
too miffed that I did not ask his permission before redistributing this.
Good hunting,
Mike
