cisco 3500 switch routing?

[patrickpoissant]

I was just wondering if the 3500 does layer 3 routing like the 3550, I would like to set up vlans on the switch and have it be able to route between the vlans, is it possible?

Thanks

Hi ,

there is no routing support on the 3500XL and there is no layer 3 routing module for the 3500 XL that exists.

Hope it helps you.

Thanks,

thanks for the response, would you be able to give me an option in order to be able to route inbetween 11 different vlans on the same switch?

3550 would do the job .... You need either a router capable of trunking (not ideal for 11 vlans) or a l2/3 switch like the 3550 .

If I put a router and use one interface to create 11 different subinterfaces for my vlans and keep one interface for routing between another network, am I overloading the router? if there is such a thing

What router are you going to use, and what memory do you have configured along with IOS?

Each router has a different architecture and routing performance.

The question is not only the amount of vlans you are routing across, but how much and what kind of traffic you are routing.

Also note that a multilayer switch, like a 3550, 3750, 4500, 6500 etc will perform the routing in hardware and be much more scaleable and quicker than a router for inter-vlan routing.

Hope this helps,

Michael.

I have a 2600 and 3600 router available, the network I need to set up is for multicasting with ghost in a classroom environment. I haven't had a chance to look at the ios or ram

yeah it is possible to create vlans on the routers which you hav specified. i have configured nearly 30 vlans on a 1700 series router in my organzation & it workz fine. it is possible by creating sub-interfaces.

eg. interface fastethernet 0/0

no ip address

interface fastethernet 0/0.1

encapsulation dot1q

ip address 10.1.1.1 255.0.0.0

in this way you can configure vlans on the router. make sure that ur not setting up any additional parameters on the fasthether 0/0, configurations has to be done only on the sub-interfaces. physcial port connected to the switch from the router should b the trunking port on the switch side also.

hope tihs helps
