[f-nsp] VPLS/VLL Redundancy

[Lazuardi Nasution]

Hi Tomasz,

The configuration is like attached picture. Each aggregation switch is
connected to two VPLS Routers as a ring. I use two  VPLS Router for
redundancy. Each subscriber device will be connected to one or two
aggregation switches side. So, I think the port based rate limitting
must be done on aggregation switches. I have no idea if I could use
VLAN based rate limitting on the VPLS router side since there are some
subsribers which have more than one node connected to the same
aggregation switch.

Best regards.
