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.

Hello everyone
I was looking around and noticed a pretty bad route from DTAG to Tata AS6453 (basically destination was Tata Comm's Indian network on AS4755). I am not able to understand cause for inefficient routing but I am sure I am failing to understand something which is crazy in their IGP. The result is that route from Europe to India is via Europe > US > Singapore > India rather then direct India.

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.
