I am trying to design a new FGT-1500D deployment to replace a Juniper firewall. The firewall connects to a pair of switches in one computer room and another pair of switches in another computer room. The Juniper is using redundant links to ensure only one up-link is active to each switch pair.
____ [Switch A]
/ >--- {Server 1}
/ ___ [Switch B]
/__/
[Firewall] __
\ \___ [Switch C]
\ >--- {Server 2}
\____ [Switch D]
FIGURE1: ASCII Topology
Going forward I would like to span a VLAN between both computer rooms. other than using a software switch and using spanning-tree are there other options I should consider (EAPS, MLAG, LACP, etc...)?
There is no connectivity between the switch pairs (though it could be added). I would like to do this with the minimum cabling required, the firewalls will be HA(a-p) and the distance between computer rooms requires fiber runs.
Worth noting, the servers attached to the switch is what effectively would create a loop. Any thoughts would be appreciated.
