Can't reach v6.testmyipv6.com with IPv6 tunnel

[kasimir]

I am having the same issue through all of my HE tunnels. From dual-homed hosts I can access v6.testmyipv6.com (2001:4830:2502:8002::ac10:a) just fine. Traceroutes are normal and it responds to pings.

However, from my two tunnels, I get the following:

This seems to impact much more than just testmyipv6.com. Any help would be appreciated.

TowardEX doesn't appear to be announcing the /32 or /48 the destination resides in to HE.NET (even though they appear to peer):

Code Select Expand

route-server> sh ipv6 bgp 2001:4830:2502:8002::ac10:a
% Network not in table
route-server> sh ipv6 bgp 2001:4830:2502::/48
% Network not in table
route-server> sh ipv6 bgp 2001:4830::/32
% Network not in table


This is something TowardEX fixes.
