Re: ATT (AS7018) cannot reach AS31334

>From what I can see, 31334 is sending prefixes covering this IP to
upstreams 1273 and 6939 (possibly others, but that's what I saw).  Neither
of these networks propagate those prefixes into 7018 directly or indirectly
so we have no path to get there.  I would encourage 31334 to check with
their upstreams to understand why the routes don't get sent to 7018.

ATT (AS7018) cannot reach AS31334

[David Hill]

Hi -

I am a ATT customer unable to reach AS31334.  Is anyone on this list
able to check into this?  It works from non-ATT route-servers I have
tested on.

ATT route-server

rvi...@route-server.ip.att.net> ping 2a02:8100:4:2::156e count 3 
PING6(56=40+8+8 bytes) 2001:1890:111d:1::28 --> 2a02:8100:4:2::156e

--- 2a02:8100:4:2::156e ping6 statistics ---
3 packets transmitted, 0 packets received, 100% packet loss

Thank you,
