    5406ZL resiliency

    Hopefully an easy one!

    We've a pair of 5406ZL's manning our core for both of our sites, linked via fibre.
    All works well but just realised something a little obvious; should one go down, the gateways that unit holds for it's vlans go also. That's not a major issue when the vlan is specific to one site, but the main question and problem is for the vlans that span sites; in our case, servers and printers. It seemed possibly only to have a single gateway (vlan IP) at the time of commissioning however that causes the above problem. Everything still works without a vlan IP but because the gateway is then gone....

    Any useful tips on strengthening this simple setup so it's not absolutely reliant on one switch?

    VRRP with MSTP should do what you need.
