On DLS1, create the SVIs for VLANs 100 and 200.
Note that the corresponding Layer 2 VLANs must be configured for the Layer 3 SVIs to
activate 

DLS1(config)#interface vlan 100
DLS1(config-if)#ip address 172.16.100.1 255.255.255.0
DLS1(config-if)#no shutdown
DLS1(config-if)#exit
DLS1(config)#interface vlan 200
DLS1(config-if)#ip address 172.16.200.1 255.255.255.0
DLS1(config-if)#no shutdown
DLS1(config-if)#exit

The ip routing command is also needed to allow the
DLS1 switch to act as a Layer 3 device to route between these VLANs. Because the VLANs
are all considered directly connected, a routing protocol is not needed at this time. The
default configuration on 3560 switches is no ip routing.
