how many vrrp groups on EX and QFX ?

Hi,

I understand that VRRP should be able to handle 255 groups per physical or logical interface.

But I have a doubt about what are the limits in Junos.

We have some EX4500 VC in production, with 200 VLANs and one VRRP group configured per VLAN.

I am wondering wether the 255 group limit is global to the switch or specific to each VLAN interface... shoud we expect a problem when we reach 255 configured vrrp group on a EX4500 cluster (global limitation : 255 VRRP groups ??) or not (if that limitation is not global, but local to each interface/subinterface).

Same question for the QFX5xxx boxes....

thanks,

Pascal
