Before I go off and try to break stuff I figured i=E2=80=99de ask if a= nyone has tried this and has any pointers . Issue one : adding more user defined bits to the custom carp Mac . So this i= s not all that common but in some cases you can have two pairs of carp serve= rs with overlapping vhids that eventually cause trouble with each other. Ha= s anyone tried this ? I am ok with random-ish mac=E2=80=99s like how crossbo= w does this on illumos .=20 Issue two: one way carp fail over . For example node a and b are carp partne= rs . Node a crashes node b takes over but there is no automatic fail back wh= en node a recovers . I can=E2=80=99t find a way to do this in 11.x . I am st= umped anyone have any built into magic for this ?=20 --- Mark Saad | nonesuch@longcount.org=
