Get 2 VLAN's to talk on Cisco 3560

Unanswered Question
Jan 30th, 2008

Hi, I have a Cisco 3560 24 port switch. 12 ports are in VLAN 2 which are home to a few PC's and a couple of servers and a Cisco 877 DSL router for the Internet and firewalling. I have created a VLAN 3 to home 4 Mac's, however how can I get these to speak to VLAN 2 for the servers and get to the Internet? I want to keep this design and not move the Mac's into VLAN 2 as this all my grow and I like to keep the Mac's separate due to broadcasts.

The 3560 should route between these vlans automatically. So in this example

vlan 2 =

vlan 3 =

1) make sure ip routing is enabled on the 3560 eg

3560(conf t)# ip routing

2) Ensure that the L3 vlan interfaces are created on the 3560

int vlan 2

ip address

int vlan 3

ip address

3) default-gateway of machines in vlan 2 =

4) default-gateway of Mac's =

5) The 877 router will need to know how to route back to vlan 3 so unless you are running a routing protocol, on the 877

ip route
