When it was not working, packets would not get from my AS (11647) to the target
in IP in AS701. But packets from 701 would get back to my AS. The AS path in
both directions are 701-6453-11647 and 11647 6453 701... I saw a similar
outage to VPNs I have in AS15290 which I see as 11647 6453 701 15290. However,
I did not have time to check if it was the same behaviour with loss being in
one direction. In both cases, IPs that follow 11647 174 701 and 701 174 11647
and 11647 174 7018 15290 and 15290 7018 174 11647 were not impacted.
