Ticket ID: SIXXS #1243351 Ticket Status: User PoP: deham01 - Easynet (Hamburg)
subnet not routed to tunnel
![[de]](/s/countries/de.gif) Shadow Hawkins on Friday, 30 October 2009 12:08:57
(at least my) subnet R5417 is not routed correctly w/i the network of Easynet.
It stopped working approximately at Oct 29 18:30 CET
It should be routed via deham01 through T11221 - which is reachable via IPv6:

So it looks like the subnet is not routed to deham01 at all - not to mention to the tunnel itself.
Additionaly, the prefix is not routed w/i deham01 - according to the SixSX Traceroute when selecting deham01 as a start point.
Thanks
Christian

Hi all,
I have a similar routing problem at deham01. My subnet R5260 isn't routed, but the tunnel T12223 works as usual, that means the address of the tunnel-interface 2001:6f8:900:93f::2 is reachable.
traceroute to the interface address of T12223 (working):
