Hello,

Is there anybody from Cisco can explain how the implementation of
load-balancing is done on the P router in MPLS core?  Let's say
we have MPLS L3 VPN and MPLS L2 VPN in place, my question is how 
the P router provides load-balancing between two customer sites 
if two or more equal paths between the two sites exist on a given 
P router?

My understanding is that the load-balancing is provided solely
based on the LSP(s) built in between the ingress PE and egress PE,
and it has nothing to do what is encapsoluated inside the label
packet because the P router has no idea of the VPN routes.
I will appreciate if somebody on the list can correct me if I am
wrong.

Thanks in advance,
Franklin
