Subject: EPICs repeater, beacon,address list, and server port

I have a simple Ethernet network.
Let's say that I have 2 computers on the same network link (no gateway).
I run several IOCs on both computers.

For IOC#1 on cpu#1, I set
EPICS_CA_SERVER_PORT=5066
EPICS_CA_REPEATER_PORT=5067

For IOC#2 on cpu#1, I set 
EPICS_CA_SERVER_PORT=5068
EPICS_CA_REPEATER_PORT=5067 ? <- same for all IOC running on this cpu

For IOC#1 on CPU#2, I set
EPICS_CA_SERVER_PORT=5070
EPICS_CA_REPEATER_PORT=5069

For IOC#2 on CPU#2, I set
EPICS_CA_SERVER_PORT=5071
EPICS_CA_REPEATER_PORT=5069

and on my OPI
EPICS_CA_AUTO_ADDR_LIST=NO
EPICS_CA_ADDR_LIST="cpu#1:5067 cpu#2:5069" 
<- i.e. ADD_LIST link to repeater instead of individual server ports?

How are IOCs aware of the presence of PVS in other IOCs?
Can I use records to link IOCs between each other (ex
sequencer/fanout/dfanout/etc. records that interact with PVS from
separated IOCs)?


Thanks for your input,
