Re: [FW-1] VRRP broadcast pollution

Hi list

Sorry if this is a trivial question, but I noticed recently that the VRRP
broadcasts being sent out by our Nokia cluster are travelling the length
and breadth of our network. I know that every interface on which VRRP is
set up has to advertise itself, but since the VRRP-interfaces of both
Nokias are directly connected with a dedicated cable anyway, I don't see
why I should see the packets travel everywhere.

hi,


you need this VRRP-traffic on every interface where you have a
cluster-IP-address configured (on the external, on the internal, in the DMZ
and so on).

the dedicated link (I guess) is for fw1-state-synchronisation, this is
important too but has nothing to do with vrrp. only vrrp and fw1-state-sync
together are a good HA-solution.

cheers
