[j-nsp] BGP VPLS support

[Bourgeois, Jacob (Jake)** CTR **]

Monika,

For VEID, my thoughts are this is a outcome derived by the RD and the 2
bytes populated accordingly, it serves the same function, i.e.
determining the outgoing label for push operation.  Maybe a developer
will weigh in on this though, as there is no way to manually configure
this that I know of.

"u-PE" is somewhat of a grey area as it is defined as a device that is
service aware, accommodates control plane set up, etc, but may not do
all of these functions:

5.  Deployment Options

   In deploying a network that supports VPLS, the SP must decide what
   functions the VPLS-aware device closest to the customer (the VE)
   supports.  The default case described in this document is that the VE
   is a PE.  However, there are a number of reasons that the VE might be
   a device that does all the Layer 2 functions (such as MAC address
   learning and flooding), and a limited set of Layer 3 functions (such
   as communicating to its PE), but, for example, doesn't do full-
   fledged discovery and PE-to-PE signaling.  Such a device is called a
   "u-PE".

Maybe this is more of a reference to a spoke in H-VPLS? Anyone who has
more of a clue please weigh in, this is a particularly interesting topic
as the service is finding its way into many core's.

As per BGP VPLS RFC 4761 section 3.2.2, "if the PE is connected to
several
u-PEs, it has a distinct VEID for each u-PE. It may additionally have a
VE
ID for itself, if it itself acts as a VE for that VPLS."

Does Juniper support connecting PE to many u-PEs?. I have this doubt as
Juniper allows only one site id configuration in the PE router.
If  connecting to multiple u-PE is supported, can any one point to the
document (configuration) to achieve this?

TIA,
Monika.
