--- Comment #3 from Kajetan Staszkiewicz <vegeta@tuxpowered.net> ---
Maybe I did not made myself clear. Carp is set up correctly and operates
flawlessly until multiple addresses are added and removed in a short period=
 of
time during some testes which are run on those routers. Rebooting routers a=
nd
having them configure the addresses once by just adding them after reboot m=
akes
things work fine again. The master/master behaviour is consistent with chec=
ksum
issues, that is when there are different carp addresses configured on each
router even when ifconfig shows identical addresses. A few times I was able=
 to
observe different addresses shown by ifconfig but I was unable to delete ex=
tra
addresses due to errors as show here before.

Long story short: only stress-testing by adding and removing carp addresses
breaks carp.

And no, it is not necessary to provide any other parameters when carp vhid =
is
already configured. Each extra IP address can be added to existing vhid by =
just
specifying vhid.
