No route to and from delegated subnet, rDNS delegation is not working
[pl] Shadow Hawkins on Wednesday, 07 September 2011 21:08:01
Dear SixXS, I have a problem with recently assigned subnet from one of the PoPs. Delegated subnet is not reachable from Internet and I can not reach any host outside PoP address space from the hosts within delegated subnet (with ICMPv6 Destination unreachable, port unreachable). Ping from delegated subnet: ping6 -c 3 ipv6.google.com PING ipv6.google.com(fra07s07-in-x93.1e100.net) 56 data bytes From gw-672.waw-01.pl.sixxs.net icmp_seq=1 Destination unreachable: Port unreachable From gw-672.waw-01.pl.sixxs.net icmp_seq=2 Destination unreachable: Port unreachable From gw-672.waw-01.pl.sixxs.net icmp_seq=3 Destination unreachable: Port unreachable Traceroute from native IPv6 host over Internet to the host in delegated subnet: Tracing route to 2001:6a0:309::1 over a maximum of 30 hops 1 6 ms <1 ms <1 ms 2a02:c10:2c10:4::1 2 <1 ms <1 ms <1 ms 2a02:c10:2c10:1::11 3 <1 ms <1 ms 1 ms dab-br1.z.dab-cr1.net.onet.pl [2a02:c10:3f00:18::2] 4 <1 ms <1 ms <1 ms ruc-br1.z.dab-br1.net.onet.pl [2a02:c10:3f00::1] 5 7 ms 7 ms 7 ms icm.ipv6.plix.pl [2001:7f8:42::a500:8664:1] 6 7 ms 7 ms 7 ms 2001:6a0:1:1::2 7 * * * Request timed out. 8 * * * Request timed out.

From gw-672.waw-01.pl.sixxs.net icmp_seq=1 Destination unreachable: Port unreachable
What is the source address that you are using, what is the route that the packet are going over? (and why is everybody always pinging google?)

When I'm using IP of a tunnel endpoint it works fine (this time ipv6.onet.pl): ping 2a02:c10:2190:4::aaaa src-address=2001:6a0:200:29f::2 HOST SIZE TTL TIME STATUS 2a02:c10:2190:4::aaaa 56 58 28ms echo reply 2a02:c10:2190:4::aaaa 56 58 26ms echo reply 2a02:c10:2190:4::aaaa 56 58 26ms echo reply 2a02:c10:2190:4::aaaa 56 58 29ms echo reply sent=4 received=4 packet-loss=0% min-rtt=26ms avg-rtt=27ms max-rtt=29ms But when pinging using source address from delegated subnet, I receive port unreachable: ping 2a02:c10:2190:4::aaaa src-address=2001:6a0:309::1 HOST SIZE TTL TIME STATUS 2001:6a0:200:29f::1 104 64 17ms port unreachable 2001:6a0:200:29f::1 104 64 21ms port unreachable 2001:6a0:200:29f::1 104 64 17ms port unreachable 2001:6a0:200:29f::1 104 64 17ms port unreachable sent=4 received=0 packet-loss=100% Strange is that if I ping the the subnet addresses from SixXS website selecting particular PoP IPv6 everything is ok: - this is the host behind the router's LAN interface

If I use tunnel endpoint address as a source address everyting works fine (ipv6.onet.pl this time, just not to ping google :) ): ping 2a02:c10:2190:4::aaaa src-address=2001:6a0:200:29f::2 HOST SIZE TTL TIME STATUS 2a02:c10:2190:4::aaaa 56 58 28ms echo reply 2a02:c10:2190:4::aaaa 56 58 26ms echo reply 2a02:c10:2190:4::aaaa 56 58 26ms echo reply 2a02:c10:2190:4::aaaa 56 58 29ms echo reply sent=4 received=4 packet-loss=0% min-rtt=26ms avg-rtt=27ms max-rtt=29ms But when source address is from a delegated subnet - destination unreachable: ping 2a02:c10:2190:4::aaaa src-address=2001:6a0:309::1 HOST SIZE TTL TIME STATUS 2001:6a0:200:29f::1 104 64 17ms port unreachable 2001:6a0:200:29f::1 104 64 21ms port unreachable 2001:6a0:200:29f::1 104 64 17ms port unreachable 2001:6a0:200:29f::1 104 64 17ms port unreachable sent=4 received=0 packet-loss=100% Traceroute using SixXS webpage to hosts within delegated subnet works fine: No route to and from delegated subnet, rDNS delegation is not working

Sorry for previous problems. I'll try not using links: When the source address is the addres of the tunnel endpoint everything is ok (ipv6.onet.pl this time :) ): ping 2a02:c10:2190:4::aaaa src-address=2001:6a0:200:29f::2 HOST SIZE TTL TIME STATUS 2a02:c10:2190:4::aaaa 56 58 28ms echo reply 2a02:c10:2190:4::aaaa 56 58 26ms echo reply 2a02:c10:2190:4::aaaa 56 58 26ms echo reply 2a02:c10:2190:4::aaaa 56 58 29ms echo reply sent=4 received=4 packet-loss=0% min-rtt=26ms avg-rtt=27ms max-rtt=29ms But when using source address from delegated subnet: ping 2a02:c10:2190:4::aaaa src-address=2001:6a0:309::1 HOST SIZE TTL TIME STATUS 2001:6a0:200:29f::1 104 64 17ms port unreachable 2001:6a0:200:29f::1 104 64 21ms port unreachable 2001:6a0:200:29f::1 104 64 17ms port unreachable 2001:6a0:200:29f::1 104 64 17ms port unreachable sent=4 received=0 packet-loss=100% Reversly traceroute to hosts within delegated subnet using SixXS website and PoP IPv6 works fine: IPv6 traceroute from plwaw01.sixxs.net @ ICM, AS8664 to 2001:6a0:309::135 : Hop Node Loss% Sent Last Avg Best Worst StDev ASN Organisation 1. 2001:6a0:200:29f::2 0.0% 5 18.8 19.5 18.4 22.8 1.8 2. 2001:6a0:309::135 0.0% 5 19.2 21.1 18.6 26.1 3.1 IPv6 traceroute from plwaw01.sixxs.net @ ICM, AS8664 to 2001:6a0:309::2 : Hop Node Loss% Sent Last Avg Best Worst StDev ASN Organisation 1. 2001:6a0:200:29f::2 0.0% 5 19.9 20.4 17.2 27.3 4.0 2. 2001:6a0:309::2 0.0% 5 16.7 20.5 16.7 28.9 4.8 Pv6 traceroute from plwaw01.sixxs.net @ ICM, AS8664 to 2001:6a0:309::1 : Hop Node Loss% Sent Last Avg Best Worst StDev ASN Organisation 1. 2001:6a0:309::1 0.0% 5 25.0 21.2 17.0 28.0 5.0 Subnet is connected to the LAN interface of the router, and default route on the router is PoP IPv6 tunnel endpoint - 2001:6a0:200:29f::1/64.

This ticket can be closed. Routing works fine without any problems. rDNS delegation problems for this PoP (plwaw01) is already reported by another user under ticket number 5652134 and marked as remote problem. Regards Wojciech Widawski
