I'm trying to plan out an HA MX deployment. We have 2 ISP connections. Our primary has 3+ static IPs for virtual IP mode. The secondary only has one static IP. Can I configure the primary with a virtual IP on both MXs, and then configure the secondary with the same IP on both? If that won't work, can I configure the primary in virtual IP mode and then configure the secondary ISP only on the primary MX? Thanks!
