Requesting some clarity (2 different questions)
1) Backbone Management
Suppose we have an L3VPN customer with 4 sites- A(2M), B(3M), C(4M) and D(6M).
And sites A, B and C, D are on opposite sides of a particular backbone link.
a) How is the bandwidth guaranteed
b) How is bandwidth reservation done in the core?
2) Bandwidth Policing:-
Let's say we have a customer who has bought 5M, out of this 2M is real-time and 3M is data-class. Is there a way where I can give entire 5M to customer when he is not forwarding any real-time bandwidth.
Please help me understand this. As evident I have just started with QoS.
I tried searching the forum and the site... couldn't find anything specific.
