We use a Nexus 9k as one of our edge routers - we don't do NAT or anything crazy, BGP with 3 peers and not taking full tables.
As many of you know its tough finding a cost effective router that can do 100gbps. The jump from a layer 3 switch to an actual router is quite big at these port speeds. I've seen some decent deals on Juniper's but I'm a Cisco guy and not sure I'm ready to make the jump.
So my question is, has anyone with a similar setup seen any major performance issues enabling sflow pushing 20gbps to 40gbps traffic at peak on a Nexus 9k? I'd like to implement this so that I can setup some automatic DDoS mitigation.
