Hi All,

I was wondering if anyone can help me with my keepalived configuration.

What I actually want to know is how to configure keepalived to healthchek
over multiple interfaces.  For example, I have two interfaces on each node
(2 node config). Both nodes have eth1 and eth2 interfaces. eth1 is a
crossover link between the nodes, and eth2 its for the network. I want to
make keepalived healthcheck with both interfaces so that if eth1 fails... it
won't failover because eth2 link is still up, and the VIP won't have to be
failovered two the BACKUP server. The only case where it should failover is
if both interfaces, eth1 and eth2 go down. Is this possible to do?

My actual configuration is:

vrrp_sync_group VG1 {
        group {
                VI_1
        }

        # to MASTER transition
        notify_master "/usr/local/bin/change_status master"

        # to BACKUP transition
        notify_backup "/usr/local/bin/change_status backup"

        # FAULT transition
        notify_fault "/usr/local/bin/change_status fault"
}

vrrp_instance VI_1 {
        state MASTER # (BACKUP for the secondary node)
        interface eth1
        virtual_router_id 49
        priority 99
        advert_int 1
        authentication {
                auth_type PASS
                auth_pass 1234
        }
        virtual_ipaddress {
                192.168.10.100/24 brd 192.168.10.255 dev eth2
        }
}


If you can see, it will healthcheck only through eth1. How can I make it
healthcheck over eth2 aswell?

Thanks for the help, it will be very much appreciated.
