We currently have all layer 2 switches with a Cisco 2851 handling the routing.
We have a data VLAN 1 (192.168.1.0/24) and a voice VLAN 2 (192.168.100.0/24).
GE0/0 on the Cisco has IP 192.168.1.1 and GE0/1 on the Cisco has IP 192.168.100.1; both interfaces connect directly to our access switches.
While the Cisco 2851 will remain in place, all switches will be replaced with two Dell PowerConnect 8132F's (stacked) and a series of Dell PowerConnect 5548P's.
The 5548P's will connect back to the 8132F's via two aggregated 10Gb fiber linkes (riding OM3 fiber).
I would like to introduce a new "infrastructure" VLAN for the switches to reside on for management purposes with network 192.168.50.0/24.
I am more experienced with software development and am a bit confused on the best approach for routing now that I am introducing layer 3 switches into the mix.
Any advise is appreciated.
