I know CARp was rewritten, but I was wndering a few things before I started. Mainly is it possible to have one machine running 9 and one running 10 with the failover working between themproperly. The reason I am wondering s that on 10 it appears you set a VHID per IP address, whereas on 9 it is per interface. I have multiple IP addresses on the carp interfces on 9, so on 10 can I simply set them up all with the same VHID, or is that not supported ? Thanks for any avice which might make Monday morning back in the office go a bit easier :) -pete.
