I am new at this so Im sorry in advance. I have created Vlan 20 on Sw 1 and Vlan 10 on switch 4. Both with ip address in the same subnet. I cannot however seem to ping. What should I be taking into consideration? Both switches are Catalyst 3750. I'm quite lost, I would appreciate any help.
You have two different vlans. You should put both switches in the same vlan and keep the addressing the same. Then under the interfaces that connect the switches, change them to either access ports for vlan 20 (for example), or trunk the port (more common).
Yes you can...both are 3750? You'll need to enable routing on at least one of them because you have to have something route for the vlan. On the routing one, you would configure both vlans. On the other you'd have just the one:
int vlan 10
ip address 10.10.10.1 255.255.255.0
int vlan 20
ip address 188.8.131.52 255.255.255.0
int f0/1 <--- Connects to switch 2
switchport mode trunk (trunks all vlans by default)
On other switch:
int vlan 20
ip address 184.108.40.206 255.255.255.0
int fa0/1 <--- Connects to switch 1
switchport mode trunk
That should do it. Technically, your 3750 that's routing will not be in a separate vlan. The only way to have them totally separated would be to have a router. You have to have a L3 device to route between vlans. Oh, and make sure you created both of those vlans on the routing switch and then create the single vlan on the second one.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
