Above section explains about configuring the Load-Balance Per-Packet Action.
It talks about installing ECMP routes in the forwarding table.  It is all
perfectly fine. It also indicates that "You can configure per-packet load
balancing to optimize VPLS traffic flows across multiple paths.".
How do we get multipaths in a VPLS cloud? We establish pseudo wire to
different edge routers and L2 flood/forward the traffic based on the FDB
table.
Even for redundancy if we multi-home, only one PE is chosen based on the BGP
selection algorithm. If we allow the traffic to flow in both the nodes,
won't that be against split horizon rule?
