Hello,
As the router at our hosting center only updates it's arp
tables every 4-hours and don't respond to gratious arp,
our failover loadbalancer don't work quite as expected ;)
let us know how you solve it.
Is there a preffered method, are you using CARP or VRRP or ???.
There isn't a preference for LVS. The differences are
political not technical. There are patents associated with
VRRP. Alexandre, the author of VRRP, has done due diligence
on the matter (as far as I can tell) and says that the
patents don't affect how it's being used by the GPL people
and anyhow VRRP is an IETF protocol, free to be implemented
by anyone.
CARP was written by GPL oriented people who decided it would
be best not to have anything remotely related to a patent.
I don't know whether one or both are right. They matter will
not be settled in the time scale that you need to implement
an LVS. CARP and VRRP do slightly different things, although
I forget what they are.
