I recall doing this back in 2014 when we first launched the CSR1000v as 
an RR.

It had about 20 clients, each needing a full feed.

We reset all sessions on the RR. Between the RR's, we are talking 
seconds to exchange the full feed. Toward the other clients, the rate of 
push was at what they could accommodate. Either way, CSR1000v didn't flinch.

In real life, we've had RR's that have lost sessions to hundreds of 
routers due IS-IS issues in recent years. Again, no hit on CSR1000v. 
That thing just keeps chugging along.

I know, more anecdotal than empirical, but my feeling is it will take A 
LOT to break a well-designed CSR1000v running on a decent server.
