We have a simple config of a full v6 bgp table, from time to time the v6 route table will not route just shows "no route to host" restarting BGP fix's it. MT support said bgp v6 is unstable
Becarra, I just started having this issue after a full year of successful transit using IPv6. I am taking a full Cogent and HE.net feed. Just in the past week Cogents feed starting including something that I believe is crashing / breaking / something when its running for a few moments now. Do you have any more details, did yours work fine until a week or so ago? Which carrier?
If I disable the he.net feed then its stable again.
I can't even ping the other end of the /126 they assigned me, which is a connected route. I get "no route to host". If i kill either bgp peer then its stable again.
