Router Performance

[strueson]

Hi,
I have a network, based on cisco products, where I would like to introduce VLANs, I don't want to change my switches with an High-End switch (with integrated Route processor).
How can I find out if a cisco router would have enough performance to route packets in between VLANs?
What is the formula to calculate the kpps needed?

Thanks for help!

What kind of switches do you have?

I have some catalyst 2950 and a 5500 without the route module.

Its kind of hard to calculate your speed needed..

You need to ask yourself, how much traffic will be inter/intra-vlan traffic? How much traffic is there? What applications are running? etc... those types of things..


the 5500 can support MLS, so you could pair it up with a 36/3700 or older 4000 router if you can find one..

Put the switch and router together in a MLS team and it will work much faster than just doing a standard router.. Its almost like having the integrated route processor..

MLS gives you "route once, switch many" process. Whereas the traditional way would be "route all, switch never"

I have both of them (3620 and 4000), the 3620 is not supporting mls but the 4000 is. Maybe I have to try to upgrade the IOS to make it supported by the 3620 as well...

Thanks for the Tip!
