Real Purpose of Route-Distinguishers

[yuchenglai]

Hi All,

I have a quick question regarding route-distinguishers.  In an ISP cloud using MP-iBGP VPNv4 to carry customer routes, do the route-distinguishers on different PE routers (each servicing the same customer at different locations) need to have the same route distinguishers on the VRFs of the different PE routers?

Secondly, are route-distinguishers carried in MP-BGP VPNv4 advertisments?  I guess this boils down to...what is the real purpose of route-distinguishers.

Any insight would be very helpful!
