So I need to connect our PC6248 to the ISP's Router. We are going to use Link networks between the devices to access MPLS networks.
The ISP router will have our internal network (172.16.112.0 /20) in it's routing table and the GW will be the link network address (192.168.0.2)
I want to subnet our 172.16.112.0 /20 into several smaller networks (/24). My question is can I go ahead and add my vlans with subnetted addresses right away on the PC6248 or do I first need a vlan with the 172.16.112.0 /20 address and the creating my subnetted adresses?
Network
172.16.112.0 /20 -----ISP-Router--192.168.0.1 /24--------------------192.168.0.2 /24--PC6248-----172.16.112.0 /20 or 172.16.112.0 /24
