As I talked about in my posting C1721 on a stick, I have acquired a Cisco 1721 router with only 1 fast Ethernet port currently, and I have configured it to be a router on a stick. Here is how to attach the router to a Dell 2716 gigabit switch.

In this example:
port 1 router(192.168.1.101, 192.168.90.101) tags its traffic and also sends other traffic to vlans

Ports 4 and 12 are in vlan 9, but they are not configured to tag or accept vlan tagging.

Step 1:
Login to the Dell 2716, create the vlan



Set the router port to ?T? so that it tags packets that flow to the router from this vlan

Then set all other members of the vlan to be U, so that the vlan tags are removed as they are sent to the device, unless your devices in the vlan are configured for vlan tagging.



Now in the vlan port settings, change the non router ports to be pvid of the new lan this makes the switch tag the traffic on the ports, and keeps non vlan traffic off those ports. And disable ingress filtertering so that the ports accept packets that are not tagged with the right pvid/vlan.

This is all you need to go, now you can test your vlan
To test vlan testing you need to add a rule on the hosts outside of the vlan, to point at the router unless you have changed your default gateway.
In my case the routers vlan 1 ip is 192.168.1.101, and the vlan 9 ip?s are 192.168.90.0/24, to make a Solaris host use the new router to route traffic to the vlan you can do


route add 192.168.90.0 netmask 255.255.255.0 192.168.1.101
