Fwd: RE: [Serusers] Multiple Registration Servers

[Corey S. McFadden]

I'm hoping to clarify a couple questions on clustering SER in high-volume 
environments as well.  Assuming authentication is RADIUS, wouldn't 
clustering something like what Darren is talking about be as simple as 
installing multiple SER boxes and just doing some DNS round-robin?  Would 
that introduce any registration issues?
