I'm whacked and obviously missing something BUT I did ask a guy who wrote a seriously good TCP/IP course years ago.
Scenario: Datacentre. 2 Soekris 5501s with a 4 port card = 4 * vr + 4 * sis One is active bgpd, other is warm standby. vr0 on #1 is 192.168.1.1 vr0 on #2 is 192.168.1.2 There is a cable directly connrcted #1 to #2 I have been syncing config files over that port<--cable->--port for ages. Suddenly it doesn't work. I can't ping either way. ifconfig vr0 on either shows same media, active, correct IP and netmask., Tech went to DC and reports: Verified no pings work on that network. Neither can he ping either unit from a PC with an IP in the 192.168.1.0/24 range. Changing cable changed nothing else. tcpdump on each end showed expected aro who-has requests without answer.when pinging on the tcpdump box. No sign of activity at t'other end's tcpdump. pf is not running. This is OT because, although we are running OpenBSD and OpenBGPd it really isn't a problem I could ascribe to the OS. OTOH I don't know where there are cluier network people.... Help? A 4*whatever is welcome. :-) *** NOTE *** Please DO NOT CC me. I <am> subscribed to the list.
