The 7206 is a router. To be a vtp server you need a switch. The IOS on 7206 can not configure any vlan database. To configure vlan database you need some kind of Catalyst switch.

Hi,

I think what you are trying to set up is MLS using an external router.As already pointed out by Rick, you need a Catalyst switch. 7206 is a router and it cannot act as VTP server.You need a cat switch which can act as a VTP server which has a packet re-write engine and caches the flow of the routed traffic so that it can switch the subsequent packets locally.

You need either Cat5500 with a Sup engine which has NFFC (netflow feature card ) on it or something like Cat6k or Cat6500 with PFC.

Thanks for the reply Amit & Rick. Both of you are right I am trying to set up 7206 as router on stick as I don’t have L3 catalyst switch (5500 or 6500). I am trying to setup small lab to practice routing and switch with the limited devices (1 2950 , 3 3500XL & few routers). Can you guys tell me if it’s possible to do so and if yes then can you help me to setup this ?

Thanks.

Hi Ritesh,

You are trying to setup router on stick which is totally different from MLS. For router on stick you have to just make a trunk on your switch and create sub-interfaces on the routers ethernet port with the respective subnets and it will work.

for example on switch

conf t

int fa 0/1

switchport trunk encapsulation dot1q (this command doesnot work on 2950 as it supports only dot1q.

swtchport mode trunk

On router

int fa 0/0

ip address 1.1.1.1 255.0.0.0

int fa 0/0.1

encapsulation dot1q 2 <-- This is the Vlan id

ip address 2.2.2.2 255.0.0.0

int fa 0/0.2

encapsulation dot1q 3 <-- This is the Vlan id

ip address 3.3.3.3 255.0.0.0

This should do it for you. Now you can trunk rest of your switches to the switch whihc is connceted to router.

Thanks for the prompt reply again. I got confused with router on stick and mls terminology. I have implemented Router on stick and it was working fine btu I wanted to play with MLS as I thought using MLS I can configure 7206 VTP server but I couldn’t get it working. I am still bit confused with MLS setup on 7206 ? Do u guys know any Cisco document which can help me or anyone of u can explain me ?

You should be able to use this equipment and set up a reasonable lab to learn and practice routing and switching. My suggestion would be to first develop a plan and create a drawing (does not need to be fancy or elaborate, but I find putting it down on paper to be very helpful) focused on physical connectivity. What is goig to connect to what. Is the 7206 going to use just one Ethernet/FastEthernet or more than one. Which device will connect to the 7206, and so forth. After you have planned the physical connections, then use that plan and drawing to plan the logical connections. In this part you will figure how many vlans will you use. are some of the vlans on a single device and are some of the vlans spread over several devices. Which of the ports will function as trunk ports, and so forth. Once you have worked through that then add to the plan the layer 3 information. The plan already has the layer 1 and layer 2 information and you are adding the next layer. Will you use more than one major network, what subnet will you use on which vlan and so forth.

After you have worked through the plan from layer 1 to layer 2 to layer 3 you are ready to connect the devices and to begin to configure them.

Best of luck with doing this.
