Routing problem with the PoP operator when reaching my /48 subnet from outside

Shadow Hawkins on Wednesday, 01 October 2014 19:23:44

Please help with this routing problem. Here I am testing networks allocated to me by SixXS from a third-party VPS. 1. Tracing my tunnel's (T102970) endpoint.

% sudo traceroute6 -I 2a02:578:5002:62::2
traceroute to 2a02:578:5002:62::2 (2a02:578:5002:62::2), 30 hops max, 80 byte packets

2. Tracing a host in /48 subnet (R254313).

% sudo traceroute6 -I 2a02:578:5418:d1:5054:a2ff:fe00:1
traceroute to 2a02:578:5418:d1:5054:a2ff:fe00:1 (2a02:578:5418:d1:5054:a2ff:fe00:1), 30 hops max, 80 byte packets

As you see, it does not reach PoP in the last case. From the host 2a02:578:5418:d1:5054:a2ff:fe00:1 (traceroute destination in second example) I can ping some hosts (e.g. www.sixxs.net) but not others (e.g. google.com). The /64 subnet is routed fine. My NIC handle is PVS2-SIXXS.

Please use the forums for debugging your issue. You will need to provide a lot more details, eg routing tables and firewall rules there though if you want anybody to look at it. Just in case:

Ok, I'll continue in Forums. The drops on hop #11 here is because of my firewall, you have to run traceroute with -I switch like I did. This is intentional and not a problem.
