I want some advice on the best configuration for my LAN in preparation for an upcoming Mitel 5000 VOIP system installation. I currently manage a 10.0.0.0/16 network with one secure subnet on 10.10.10.0/24 using an ACL on one of my HP 2910al layer 3 switches. Ideally I want to create another subnet soley for VOIP. VLAN 1 default is for users and they are assigned an IP via DHCP scope 10.0.1.1 - 10.0.2.254, the second scope is 10.10.10.10 - 10.10.10.200, this is VLAN 10. My aim is to provide all ip phones an ip range of 10.10.20.10 - 10.10.20.200, creating a third scope. I have two Cisco routers which are managed by my hosting provider, these are setup using HSRP. I have 3 HP 2910al layer 3 switches as the core, with 6 HP 2520-24 port POE switches to provide power to these ip phones. Happy to provide configs of any switches and I do have the configs of the Cisco routers from my provider. Help appreciated.
