Looking for some opinions, advice or best practices on our remote office LAN configurations. We have 16 basically identical sites. Within the last year we have started deploying VoIP at these locations by adding them to our Call Manager, and soon we will probably deploy wireless at these sites by adding them to our central wireless controller with the H-REAP model.
My concern is that over time our simple access router and switch configs have been modified by various network engineers just to get things working, but not necessarily the best practice; or maybe they are.
Attached are the abbreviated configs and diagram of our typical 1 router, 2 switch VoIP site without any wireless H-REAP stuff yet. I'm primarily concerned with the routing, and switching vlans and connectivity from switch 2 back to the router should switch 1 fail.
ideally if you revert to 3 point to point Layer links between the router and the two switches you keep away STP from the picture but you should use different client vlans on the two switches, if you need a L2 trunk between them one vlan more or less makes no great difference
use the unused FE on the C2811
Hope to help
