Problems with HE /48 IPv6

[bmifmaily]

Hello guys,


First off, I apologize if this has already been discussed. I saw some similar threads, but I'm not sure if it's the same issue that I'm having, so therefore I'm opening a new one.

Anyways, I'm having issues with accessing certain IPv6 hosts from my computers that have the HE /48 IPv6 assigned to them. My router has HE /64 assigned to it, and it has no issues as far as I can tell, the problem is only with hosts with the /48 assigned.

Here's an example:

Ping from my router and traceroute(/64 IPv6 assigned to it):

-------
$ ping6 -c3 www.he.net

64 bytes from he.net: icmp_seq=1 ttl=57 time=79.9 ms
64 bytes from he.net: icmp_seq=2 ttl=57 time=80.1 ms
64 bytes from he.net: icmp_seq=3 ttl=57 time=79.9 ms

--- www.he.net ping statistics ---

Here's what the same looks like from my hosts running the /48 subnet:

Keep in mind that my /48 hosts can access other IPv6 address without any issues:

So the issue is only happening when I try to access certain IPv6 hosts such as www.yahoo.com or www.he.net.

Anyone have any ideas as what what's going on?

Thank you in advance.

Anyone have any ideas as what what's going on?

Maybe the routing entry for your /48 has not propagated everywhere in the HE network. You should file a ticket with ipv6@he.net and ask them to look into it.

You can use http://lg.he.net/ to see what the traceroute looks like from the other end. I don't know if it will provide any additional clues.

Thanks a lot for the response kasperd!

I've gone ahead and opened a ticket with HE. I'll see what their response is.
