ISR: 2901 with ISM
iOS: 15.7
I have several vlans setup on my networks. Everything is inter-vlan routed through my 2901 routers because day to day maintenance for firewall and zones is easier with the cisco configuration professional express. For the most part, everything works great. All the vlans in my LAN zone are able to communicate just fine-- however when I when I enable Hyper-V replication on a specific machine between 2 specific vlans between I get really high CPU usage which brings down my CME. Both vlans are in my LAN zone. I've included the configuration for the specific vlans-- not sure if there's anything else I should look at.
