Hello
we have CiscoISR4000 series router with gig ports. We are planning to have a 4G/5G line as a backup. I need to know do i need to install a new module NIM-4G-LTE-GA module, or we can have ethernet cable from another 4G gateway and connect to Gig port to Router. In Meraki the cellular gateway appliance is connected to MX FW appliance as an uplink and it works. Not sure if it can be done with ISR4000. any idea?
