Hey there!
In our environment we generally have ASR-1000X-2s everywhere peering via
iBGP/eBGP. These routers have no redundant RPs, hence cannot keep
forwarding traffic while the router reboots or crashes. As such, this is a
clear example of a router that's only NSF-aware (or graceful-restart-awar

Marcus,
From route-views output, it looks like AS9498/airtel is probably
leaking your route between two of its upstreams (AS6453/Tata and
AS4637/Telstra) overseas, funneling some of your traffic through their
router.

FYI 29791 isn't the only origin I'm seeing this on from one point of view:
AS path: 3257 6453 9498 4637
AS path: 3257 6453 9498 4637 10310 26085 14210

AS path: 3257 6453

I have tried to reach out to Airtel, no response yet, but yah I could see my
issue being due to them leaking routes.

I don't know what's less surprising, Tata making sure you see the entire
internet (wink wink), or Airtel leaking routes... :)
