Thankyou. I remember VRRP being a bit of a mess from inception due to the Cisco patent claims against the original IETF draft (too similar to their patented HSRP). Are there still a lot of compatibility problems across vendors? At home I used to use CARP (Common Address Redundancy Protocol) on OpenBSD, but I haven't done it for awhile, and I know it's improved a lot since then (i.e. pfsync(4), ifstated(8), ...).
