PfR

Hi there,

 

There is one thing that I can't quite understand about the requirements of PfR's implementation:

Why do I need 2 Routers at the Hub site, why I can't have just one Router like at the Branch or Regional Hub sites? What is the actual technical limitation for this?

The answer that I got for this question:

- it's not recommended by Cisco - it doesn't follow the Cisco design guide;

- it is not possible today:
•? CEF behavior can prevent Spoke-toSpoke tunnel setup
•? Must have one BR per transport network (per tunnel)

Can someone please help me understand that.

 

Thanks!
