Router On a Stick 1

[mookee1]

Anyone know if it is possible to have a Cisco 1605R Router be used in a Router on a Stick configuration. I heard somewhere 10baseT ports would not work...

thanks,

Could be an IOS problem. What exactly are you trying to accomplish????

If by router on a stick you mean assigning multiple secondary IP addresses, yes it will do this.

What it won't support is running an 802.1q trunk to its directly-connected switch port allowing you to create multiple vlan subinterfaces for routing purposes.

The latter method is the more widely-adopted approach however the first approach will work also. The knock on the first approach is it's not very scalable and could lead to problems with network broadcasts.

Basically I am trying to accomplish the same thing that I would have if I had a Catalyst 4000/6500 with the Internal router processor.

This is strictly for home lab purposes so, if it was something where performance is a issue, I do not mind.

My plan is to connect a cat 2950 to a 1605R "trunked" the cat is going to have many VLANS, (Same as on a 4000/6500)I am going to then route the VLANS through my trunked interface, by what I hoped was router on a stick, but not sure if the 1605 gives me what I need.....

Any suggestion to accomplish the same thing are welcomed.

Thanks!

you should beable to create virtual interfaces
ie int eth 0/0.1
just add the subnetted vlans ip to the virtual port ,should work.

I'm pretty certain you won't be able to setup a trunk and then create subinterfaces on the 1600. This is because the 1600 doesn't support the 2 trunking encapsulation methods available - 802.1q and ISL.

As this is a lab, I'd just follow the approach I mentioned earlier, i.e. just create multiple secondary IP addresses on the 1600's e0 interface for each subnet you want to route.

e.g

int e0
ip address 1.1.1.1 255.255.255.0
ip address 2.2.2.1 255.255.255.0 secondary
ip address 3.3.3.1 255.255.255.0 secondary
etc
etc

This should work for you.
