Hello folks.
I'm trying to allow end devices to communicate between vlans.
I I'm using a Multilayer Switch 3560 24 port. And 4 computers. 2 per vlan.
NAME | VLAN | IP |
PC10_1 | 10 | 10.100.10.50 /24 |
PC10_2 | 10 | 10.100.10.51 /24 |
PC20_1 | 20 | 10.100.20.50 /24 |
PC20_2 | 20 | 10.100.20.51 /24 |
GW: 10.100.X.1
I have created a Virtual Switch INTERFACE, one for each VLAN.
interface Vlan10 - ip address 10.100.10.1 /24
interface Vlan20 ip address 10.100.20.1 /24
Devices can ping eachother and the virtual gateways, but not between vlan.
I assume there is a encapsulation dot1Q needed.
Which interfaces should have this?
Solved! Go to Solution.

Hello.
Could you please post the 3560
show run?
Communication with the GW is possible, so maybe the
ip routing
command is just missing.

I linked it at the bottom.
But I figured out what was missing.
I needed to type in the follwing in global config mode
ip routing

BTW, some Cisco L3 switches have IP routing disabled by default, others Cisco L3 switches have it enabled by default.

Hello @mblackshore,
No need of dot1Q here.
Active routing between VLAN with
ip routing
command in switch configuration mode.

Check for
ip routing
command....in Global configuration mode....
MLS(config)# ip routing
You no need to give
encapsulation dot1q vlanX
command.....This command is required when we are doing
inter-vlan routing
by using Router....on router each sub-interface you will be needed give that command... not for multilayer switch with SVI.
I hope the above information is useful...
Thanks
