I got two firewalls running Keepalived and working ok. I would like to pass the vrrp multicast traffic bethween a direct back to back link between those firewalls (that direct link is already used by conntrackd).
In order to do that I did add a route like that : 220.127.116.11 * 240.0.0.0 U 0 0 0 eth3
Using the command : route add -net 18.104.22.168 netmask 240.0.0.0 dev eth3
But if I type iftop -i eth0 -f vrrp, I still can see multicast traffic on that link and no vrrp traffic at all on eth3...
Any idea why my route is ignored ?
