VLAN Routing Configuration
The VLAN chapter in this guide (VLANs on page 207) contains a detailed explanation of enabling an IP
VLAN (routed VLAN) on one S-Series switch. See Creating a Routed VLAN on page 217. The example
in Figure 17-238 is a quick refresher on the sequence of commands that you execute on each switch
participating in an IP VLAN:
Figure 17-238. Creating an IP VLAN
Remember that assigning an IP address and subnet mask to the VLAN automatically enables routing on the
VLAN, in contrast to specifically enabling routing on a port.
Example of creating a routed VLAN between switches
Note that, if routing is configured on a port that is a member of a VLAN, that action removes the
interface from the VLAN. Disabling routing on the interface restores the interface to the VLAN.

1. Enable the routing globally on switch R1:
Figure 17-240. Enabling Routing Globally on a Switch
2. Create an IP VLAN (a routed VLAN) on switch R1and add port 22 to it:
Figure 17-241. Creating an IP VLAN
3. As above, enable routing on R2:
Force10 #configure
Force10 (Config)#ip routing
Force10 (Config)#interface vlan 5
Force10 (Conf-if-vl-5)#ip address 10.10.3.1 255.255.255.0
Force10 (Conf-if-vl-5)#tagged 1/0/22

R1 (Config)#ip routing
R1 (Config)#interface vlan 200
R1 (Conf-if-vl-200)#ip address 10.11.12.144 255.255.255.0

R2#configure
R2 (Config)#ip routing
