active/passive BGP - Data plane VLANS

L2 Linker



I'm doing an active/passive set up with BGP. I will have a router to a the active FW. I will have different router to the passive FW. The second FW will only have BGP peers up when the active FW fails. 


I am going to have VLANS for the HA 1 and HA2 links. 

Do I need to have the data planes (data port dmz interfaces) spanned across the FWs are well? 

For example,

FW A interface 1 is in Vlan A

FW B interface 1 is in Vlan A


Does VLAN A need to be connected between the FWs?

assuming the same servers will be reached when firewallB becomes active, yes you will need a vlan to span the DMZ
