Cisco 2821/Dell 6248 Vlan question
Posted on 2010-11-29
alright, i have 2 new 6248 connected by fiber in the same building into an existing network which uses a 2821 to handle routing for the multiple campus vlans, so there are currently several sub interfaces on the router already. I want to create a new vlan to be used with some of the ports on the new 6248's. To do that, i would create the new vlans on the switches , assign whatever ports i want to that vlan, create a sub interface on the lan facing interface of the router, set dot1q encapsulation and the vlan number and set the ip to be the .1 of the subnet i want to use? Just thinking outloud and getting confirmation. also I would need to specify on the sub interface the ip helper for the campus dhcp server, correct?
