I don't think running OSPF on the CARP interface will work, cause the CARP interface receives nothing while at BACKUP mode. 2) Specify the router-id yourself to avoid OpenOSPFD's autoselection, remember that the CARP interface has the same IP address on both hosts and that's not very nice to OSPF:) > the links failover+loadbalance comes naturally after ospf > running. No, OSPF cannot provide load balancing, as FreeBSD does not support equal cost multipath routing, that is you can use one and only one next hop for a destination. So, in short, OSPF will not do load balancing, as it does with other vendors you may be familiar with. If you run CARP on the LAN links as well(which you probably do), you should test and see how CARP's ARP level load balancing fits your network... Hope this helps a bit, Nikos
