Two systems running identical hardware and software (one system actually rsync'd from the other). Running 10-CURRENT just after the new CARP implementation went in: FreeBSD nexus2.sd73.bc.ca 10.0-CURRENT FreeBSD 10.0-CURRENT #1 r245195: Thu Jan 10 10:29:16 PST 2013 root_at_nexus2.sd73.bc.ca:/usr/obj/usr/src/sys/NEXUS i386 Each box has 2 interfaces configured: em0 is part of an untagged vlan em1 is part of 8 tagged vlans The tagged vlan interfaces work correctly on both boxes, and CARP switches back and forth between MASTER and BACKUP correctly, whether it be via unplugging the network cable or via "ifconfig ... state" changes. The untagged vlan on both boxes will not relinquish MASTER status. If both boxes are up, both em0 interfaces are up, then both boxes configure the vhid as MASTER and nasty things happen to our traffic. The network configuration is: [remote site]------fibre link--------[fibre switch]----------[carp box1]--------[internet] [remote site]------fibre link----------/ \------------[carp box 2]-------/ [remote site]------fibre link---------/ The fibre links to the fibre switch are on untagged vlans; the link from the switch to each carp box is a tagged vlan trunk. And the link from each carp box to the Internet router is an untagged vlan. If only box1 is online, everything works correctly. If only box2 is online, everything works correctly. If both boxes are online, everything on em1 works correctly, and em0 shows MASTER on both boxes. If both boxes are online but em0 is down on 1 (either) box, everything works correctly. Running "tcpdump -n -i em0 -T carp | grep CARP" on both boxes shows the CARPv2 traffic from both boxes, with the correct vhid, advbase, advskew for each box. But the logs on box2 show "master down". I'm at a loss as to what to try next. Everything works for all the vlan interfaces on em1. But nothing I've tried works for em0. Within 2 seconds of the link showing UP, it becomes MASTER. On both boxes. -- Freddie Cash fjwcash_at_gmail.comReceived on Wed Mar 27 2013 - 20:02:46 UTC
