Heu Michael But this time AS4755 wasn't their customer. It's their own network in India! I think probably it will be hard for us and in general for technical community to comment on business side of it but I am just curious on technical side on what it is like that? Is it missing iBGP sessions or just intentional filtering of a group of prefixes via a peer group or based on some community tag? Thanks.

The resultisthat route from Europe to India is via Europe > US > Singapore > India rather then direct India.<snip> I think you'll find that these decisions are intentional and driven by the cost of routes headed direct over land from EU to India. Ask Tata for a price quote for transit internet services in the EU and, separately, for transit internet in the EU that go direct from EU to India. They are not the same price. Regards, Mike
