Our estate runs Firepower 1120s in ASA mode running firmware 9.14.2.15. We found an ASA with firmware 9.16. Strangely, the 9.16 firmware was nowhere on disk0:, but after each reboot, the boot would persist to 9.16. We...
We have a very basic Inter-Vlan routing setup on Cisco IE2000 switches. Devices in each Vlan can reach their respective gateways and route between each other.

If we configure them as separate hosts in our SNMP software using their interface IPs, everything is fine till ...
So we use a Cisco DMVPN setup with 2 Hubs and multiple Spokes. We use OSPF for routing over the tunnels.
Currently, everything is working well. However, I notice that each Spoke is load-sharing traffic to the Hubs via both Hub routers.
