IP ADRRESS ISSUE AND ROUTING

princesegunloves · ‎06-22-2009

I have two switch and a router.I will name them switch A and B. SwitchA is connected to f0/0 of the router and switchB is connected to f0/1 of the same router.

SwitchA is connened to a lan network which is 172.1.30.0/24 network.which the interface f0/0 is 172.1.30.50.

SwitchB: The first five port on B is connected to AP which has these netwotk bellow.

Portf0/1-----172.16.10.0

portf0/2-----172.16.11.0

portf0/3-----172.16.12.0

portf0/4-----172.16.13.0

portf0/5-----172.16.14.0

and the f0/24 is conneced to the f0/1 on the router.

What ip would i give the gateway to the switchB and i would i route the network to the other lan

Hi, you need to do some changes,

you can do it in two ways

1. the easier way - Use a supernet for all the AP subnets

192.168.8.0/21 and assign the router int f0/1 IP = 192.168.8.1/21

And on all the hosts in the Switch B, set default gateway as 192.168.8.1

But this way it won't be secure and not a good solution.

2. Use different vlan for each of the ports on swtch B,

port 1- vlan 10, port 2- vlan20,port3-vlan30,port4-vlan40,port5-vlan50

and the port24 as trunk port.

On the router interface f0/1, create subinterfaces for each vlan.

f0/1.10 - vlan10 - ip 192.168.10.1/24

f0/1.20 - vlan10 - ip 192.168.20.1/24

and so on.

So, the host on 1st port using subnet 192.168.10.0/24 will use GW as 192.168.10.1 and so on.

Hope this helps.
