C9300 and C9500 how many VRFs supported?

[alberx]

Hi all,

I can not find in data sheets or FAQs how many VRFs are supported in C9500 or C9300.

Does someone know where can I find this info?

How many you need?

About 200.

There is no problem' I was think more than that.

Possibly it might be a platform resource limitation rather than a hard cap max number.  If so, there might not be an actual number limit.

Q.  What is the maximum number of VRF instances that I can configure on the Cisco Catalyst 9000 platform?

A.  The maximum number of VRFs that you can configure on the Cisco Catalyst 9300, 9400 and 9500 (C9500-16X/40X, C9500-12Q/24Q) Series switches is 256. For Catalyst 9200 Series switches the maximum is 4 VRFs on the modular models and 1 VRF on fixed models. For Cisco Catalyst 9400 (with C9400X-SUP-2/2X), 9500 (C9500-24Y4C/48Y4C, C9500-32QC/32C) and 9600 Series switches the maximum is 1K VRF’s at FCS.

OK. Many thanks.

".  . . and 9600 Series switches the maximum is 1K VRF’s at FCS."

That statement would imply the limit may increase in later releases.  Similar might happen for other c9k platforms.  Possibly some of these limits might be more due to provide an up sell feature for the larger platforms.

Although such limits should restrict the number of possible VRFs, for limits like 256 or 1k, you may exhaust platform resources first.

I.e. such limitations might be somewhat analogous to the number of OSPF areas and/or processes a router or L3 switch can actually reasonably support.  With OSPF or VRF, besides number of instances, much often depends on resource demand of each instance.

@Joseph W. Doherty  sure that is reference guide to start the OP, yes every day is new in the technology as day passed, new day start with new thing. so always we refer release notes and features.
