communicate between two vlan

[lynbuehler]

How do I make the vlan 100 on the interface 0/0 on the router forward to the 200 vlan on the interface 0/1 of the router and vice versa?

Hello @lynbuehler 

Since you have configured Fa 0/0 and 0/1 as sub interfaces with the vlan tag, routing between vlan should be ok !

int fa 0/0

no shut

int fa 0/0.100

encapsulation dot1q 100

ip address x.x.x.x. mask

no shut

int fa 0/1

no shut

int fa 0/1.200

encapsulation dot1q 200

ip address x.x.x.x mask

no shut

how is your configuration looks like on the router - show run help here.

if they are configured already VLAN 100 and VLAN 200 on Router - IP routing help you to route the traffic.

If i understand correctly you looking VLAN 100 and VLAN 200 network should able to communicate each other. (post show run)

Hello lynbuehler,

Make sure on Fa0/0 and Fa0/1 you have given no shutdown.....according to diagram...it seems you have given.

You will be needed to configure sub-interface on each physical interface...

Int fa0/0.1

encapsulation dot1q 100

ip address x.x.x.x sunetmask

int fa0/1.1

encapsulation dot1q 200

ip address x.x.x.x sumnetmask

All PC's make sure you have given correct ip address, subnetmask and Default Gateway

I hope the above the information is useful....still if you have issues...Please share the configuration...
