I have a client who is interested in 2 x SDX Pro’s in High Availability w/ LTE modules. Has anybody done this before? I’m curious how the LTE connections and respective SIMS behave in HA when a failover occurs.
Would I need to have LTE expansion modules in each of the routers?
If yes - would I need active SIMs in both modules or would the backup router be able to use the SIMS in the primary’s module?
What would happen to LTE traffic during a transition between HA units?
