No route to and from delegated subnet, rDNS delegation is not working

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
