In a scenario where we have an SRX650 HA cluster, with one device on one floor and the backup on another floor in the same building, with the control & fabric cabling running to switches - instead of being directly connected via ge-0/0/1 & ge-0/0/2, is it required to create seperate VLAN for each port (ie.. one VLAN for the fabric heartbeat & another VLAN for the control link heartbeat) or can both links use the same VLAN?
So referencing the KB21145 instructions to create this HA cluster with only the 4 available ports, how does one setup the physical cablilng to both the WAN switch and the internal LAN switch? I would think if LAN/WAN/DMZ sub-ints are all off one physical interface, can this port be connected to the internal switch and the management links to external switch or both ports to a single internal switch? Any diagram would be helpful. Thanks for your support.
