Imagine one has
HeadquarterCE---------(PE1 MPLS PE2)----------CEBranch1
From reading the documentation below, I see the associated configuration that service provider would do in order to make PE and P routers as PIM neigbhors.
From a customer perspective, what are the configurations left for the CE routers?
I mean, I am just trying to understand how using multicast implemented on the MPLS network will save work and configuration time for customers.
