Hello!

I want to ask that what is the minimum requirement(In terms of the number of P and PE routers required) if I want to connect my 5 data centers in different cities together by bulding my own MPLS backbone(my own cloud). This is just a private setup and we are not serving any clients. Currently the connectivity is via p2p E1 links.

Thanks

Hi,


There is no such requirement. P are used to aggregate traffic between PE's.


Because in your case, you have only 5 sites, I don't think you need P routers as you can fully-mesh or build a ring between your sites. The number of links depends on the level of redundancy you want.


Don't forget a PE acts also as a P.
