Hi all,
I'm working on a solution that will require multiple vrf's on a 3560, but I can't find how many are supported on the platform.
I appreciate that the SDM template may have an effect but I ultimately need to know how many vrf's I can go up to.
During testing with 3550's it would appear 4 is the maximum with routing extended match sdm template.
Many thanks in advance

Hi,
I believe 3560 share the same architecture as 3750. Check the 3750 Q&A

Hi,
In addition to what Lei noted, I actually tried this on a 3560. The maximum is 25 and cannot create 26, see below:
xx-cx(config)#ip vrf 26
% Can't create VRF 26
xx-cx(config)#

Thanks for replying.
On the 3550 I was testing with the message "%L3TCAM-3-TOO_MANY_VRF: The maximum number of VRFs allowed has been exceeded"
Only came up when I created a new VLAN added it to the vrf and then added the IP address.
I read on one forum that the 3550 only supports 4 vrfs but 8 are configured the message only came up as I created interfaces in the 4th vrf.
So I guess my question is if the 3560 supports 25 or there about vrfs has anyone tried to add actual interfaces into those vrfs ?
Really helpful posts so far, really appreciate it

Clive,
Are you talking about 3560? if yes, the maximum is 25
xx-cc(config-if)#do sh run int vlan 145
Building configuration...
Current configuration : 62 bytes
!
interface Vlan145
ip vrf forwarding 25
no ip address
end
xx-cc(config-if)#
Here is the IOS ver:

Take a look at this document:
It lists all of the limitations for using VRF's on the 3560's. (it's 26 by the way).
