Help with Vlan creation and assignment
Posted on 2008-10-15
Let me start by saying I am a beginner with cisco routers, I am studying for my CCNA, and just got ahold of a Cisco 2811 router. It has a 4 port HWIC card in it. Like I said I am studying for the CCNA exam, so I am trying to try all possible configurations.
What I wanted to do was subnet a class A network ( 10.0.0.0 ) into 4 subnets using 255.192.0.0, easy enough. Then I wanted to assign the four subnets each to it's own port on the HWIC card, so 10.0.0.0 to fa 0/0/0 and 10.64.0.0 to fa 0/0/1 and so on. Then I wanted to cable each port to different floors in my house and use the fourth subnet to connect to a WAP so wireless had its own subnet. As I said there is no real need for this at my house, but I want to know how to do. So I began, and discovered that L2 Links can not have ip addresses assigned to them. Someone said that in order to use these ports you need to assign them to a vlan, but I can't figure out how to create multiple vlans in the router, assign each port to its own vlan, and then assign each vlan to pull from a specific dhcp pool so it stays in it own subnet. Lastly, I guess since I am using multiple vlans, i will need to trunk them all together so I can transfer info between them all??
Thanks for the help.
