routing outages miredo (teredo) -> HE tunnel
« on: February 07, 2011, 04:54:47 AM »

Hello,

I'm using miredo (on OS X, using MS teredo servers) in order to connect to an he tunnel endpoint. Furthermore, a routed /48 is assigned at the endpoint, while routed::1/64 is assigned to a tap0 interfaces.

ping6'ing / traceroute6'ing the tunnel endpoints works:
Code: [Select]
traceroute6 to 2001:470:1f14:1460::2 (2001:470:1f14:1460::2) from 2001::5ef5:79fd:144f:2b4a:abc0:f757, 64 hops max, 12 byte packets
 1  6to4.ams1.he.net  148.701 ms  17.655 ms  17.517 ms
 2  gige-g2-9.core1.ams1.he.net  75.146 ms  18.464 ms  25.435 ms
 3  gige-gbge0.tserv11.ams1.ipv6.he.net  67.565 ms  22.549 ms  21.516 ms
 4  yanosz-1-pt.tunnel.tserv11.ams1.ipv6.he.net  30.856 ms  29.649 ms  28.884 ms

while route::1 has temporary, non-deterministic outages:
(non-working example)
Code: [Select]
localhost:~ jan$ traceroute6 2001:470:d600::1
traceroute6 to 2001:470:d600::1 (2001:470:d600::1) from 2001::5ef5:79fd:144f:2b4a:abc0:f757, 64 hops max, 12 byte packets
 1  2001::5ef5:79fd:144f:2b4a:abc0:f757  0.486 ms !A  0.647 ms !A  0.307 ms !A
localhost:~ jan$

working example:
Code: [Select]
traceroute6 2001:470:1f14:1460::2
traceroute6 to 2001:470:1f14:1460::2 (2001:470:1f14:1460::2) from 2001::5ef5:79fd:144f:2b4a:abc0:f757, 64 hops max, 12 byte packets
 1  6to4.ams1.he.net  148.701 ms  17.655 ms  17.517 ms
 2  gige-g2-9.core1.ams1.he.net  75.146 ms  18.464 ms  25.435 ms
 3  gige-gbge0.tserv11.ams1.ipv6.he.net  67.565 ms  22.549 ms  21.516 ms
 4  yanosz-1-pt.tunnel.tserv11.ams1.ipv6.he.net  30.856 ms  29.649 ms  28.884 ms
localhost:~ jan$

For some reason (in the non-working example), packets didn't go beyond localhost. While pinging the tunnel endpoints works at the same time...

Do you know what's wrong here? Is it a miredo issue?

Thanks,
Keep smiling
