Do you know of any "vpn exchange point" implementations please? -I mean something like IXP but for mpls vpns
Let's say I'm an ISP that bought or merged with many small ISPs each with it's own AS# and would like to start offering mpls vpn services end to end
In the MPLS world, this type of interconnect is called NNI (Network to Network Interconnect) and it needs to take into account things like COS mappings. I don't know of anyone doing this as an exchange, But I imagine that if you had a router with a private ASN, you could always do NNI with a different ASN on each port and therefore, achieve something analogous to an IXP. But you could only do this if you control all the ASNs involved, because vPn is a form of private network, so you need a higher level of trust with the other ASns. Most MPLS providers only use this to extend their reach into a territory where they will likely never build PoPs. For instance, to get good coverage of Russia, population 150 million, or the 4 Nordic countries, you could either build loss-leader PoPs, spend lots of money on longlining or do NNI with an MPLS provider that has good coverage because they focus on smaller regional customers. --Michael Dillon P.S. If you do this, it would be interesting to report back to NANOG on how you configured it, and what are the strengths and weaknesses.
