Spanning tree is not enabled in the switch. Here's my freevrrpd config from the primary machine. secondary is the same but with 200 for priority. serverid = 1 interface = em0 priority = 255 addr = 192.168.13.209/32 password = dlvip useVMAC = yes carriertimeout = 3 spanningtreelatency = 0 sendgratuitousarp = yes monitoredcircuits = yes AHencryption = no #masterscript = "/usr/local/bin/master_script.sh" #backupscript = "/usr/local/bin/backup_script.sh" Now I can start freevrrpd and within a few seconds the machine is reachable again. if I shut down freevrrpd the machine becomes unreachable for some period of time greater then my ssh timeout. If I start up freevrrpd on the secondary server I get : freevrrpd[64090]: authentification incorrect in a received vrrp packet. Packet is discarded ! And of course at this stage network to both machines becomes flakey as they fight over the vip. Is there a simple patch for .8.7 that makes em0 work? Unfortunatly I was expecting this to be as plug and play as it is on fxp cards, so I'm short on time before my decision point of wasting a few hours on a colo trip to swap the cards out.
