[HECnet] Adjacencies Keep Bouncing

[Johnny Billquist]

Just a few comments...

8.400 (GORVAX) is a SIMH VAX, according to the nodename database.

I see the same issues with GORVAX and KUHAVX (47.556) also on MIM.

Both machines (and areas) are run by Sampsa. Not sure how relevant that is...

I have not done any further looking at actual packets yet. I might if I find some time. But it do seem there is some kind of problem/issue here.

Here at 5.1023 I keep experiencing certain adjacencies going up and
down. At the bottom of this email is an extract of several hours of my
log (all times are UK local time, current GMT+1).

Last night I investigated one of these, when 8.400 went down at
2014-06-28 22:04:03. I used a packet sniffer and could see that my
Ethernet Router Hello message went out, with 8.400 in it, at the
following times:

22:03:18

22:03:23

22:03:33

22:03:38

22:03:48

22:03:53

I did not send any Ethernet Router Hello messages in that period that
excluded 8.400.

Conversely, from 8.400 I received Ethernet Router Hello messages, with
5.1023 included except where noted at the following times:

22:03:28

22:03:29

22:03:30

22:03:45

22:03:46

22:03:47

22:04:03 (5.1023 missing)

22:04:04

22:04:07

22:04:08

22:04:09

22:04:25

22:04:26

So here are some interesting things about the above information.

1. I am supposed to send out the Ethernet Router Hello every 15 seconds.
