I'm a little confused on having the ping node setup and what happens with the ping node goes down.

My setup is 2 DSS machines identical setup, 2 dedicated iSCSI only switches. 2 dedicated internet traffic switches.
SAN1 primary node
SAN2 secondary node

Switch01
Switch02
Switch03
Switch04

Switch01 and Switch02 carry all "live/internet traffic"
My router has a bond connection to Switch01 and Switch02, my router is also the ping node. 202.xxx.xxx.1

6 nic's in both dss machines.

eth0 through eth3 is VIP for iSCSI failover and MPIO.
eth0 and eth1 are connected to Switch03
eth2 and eth3 are connected to Switch04
eth5 is directly connected to the other SAN for dedicated volume replication
eth4 on SAN1 is connected to swtich01/eth4 on SAN2 is connected to switch02
eth4 and eth5 are ticked as my auxiliary connections for failover.

Switch03 and Switch04 have a 4 port Trunk with LACP between both of them, they have no "external" connectivity, they can't see the ping node.
Switch01 and Switch02 have a 2 port Trunk with LACP between both of them.

eth0 10.1.5.100
eth1 10.1.6.100
eth2 10.1.7.100
eth3 10.1.8.100
eth4 202.xxx.xxx.70 (.71 on SAN2)
eth5 172.16.1.1 (.2 on SAN2)

I have my ping node as 202.xxx.xxx.1 which is the IP on my core router.

My failover is setup as broadcast.

Soooooo now my questions.
Router is rebooted.
What happens to both nodes? They both will lose contact with the ping node, but my system is still 100% stable.
Switch01 fails, SAN1 will lose contact to the ping node. What happens then? my san network is 100% fine as I have multiple switches and dedicated iSCSI switches, will it failover? likewise if Switch02 fails, what will happen to SAN2?

How do I change my config so that the ping node isn't factored into failover, if I have duel aux connections I don't want the ping node to cause issues.
