Catalyst 3750 Question EASY

Hello Everyone,

I wanted to know if the Cisco Catalyst Switch model 3750, if configured to work as a L2/L3 can handle close to 10,000 routes.

What is the maxium amount of routes that it can handle??

I would like to configure it for BGP and ISIS.

Please and thank you..

Hmmm, if it's so easy why don't you know the answer :-)

Depends on the model but most of the switches support up to 11000 unicast routes - see attached data sheet (Table 2) -

Re: Catalyst 3750 Question EASY

I found this:

Configurable up to 20,000 unicast routes (Cisco Catalyst 3750G-12S on the url that was published.

The Cisco Catalyst 3750G-12S is the model we have in mind to deply.

I guess my question was regarding if anyone has ever done it and how the Switch behaves..

If that model can handle 20,000 routes were good if it can handel only 11,000 it may cause some issues..

Just wanted to get some info or suggestions from other Cisco Professionals..

Let me know

The link I posted provides the information that you need. One thing though, don't use the 11k and 20k numbers, use the indirect routes numbers as the baseline (8k on desktop template and 14k on aggregator template)

You are looking at 11k routes but only 8k can be indirect routes:

Make sure to change the SDM to routing.
