Hello, My handle is SHU4-SIXXS. I'm using tunnel T68753 with grath01 and I just got subnet R31217 (2001:648:ff0d::/48). It seems that traffic for this subnet is not routed to the tunnel (yet?). While running tcpdump on the tunnel endpoint, i did some pings from two ipv6 looking glasses to address 2001:648:2f0d::1. Both of them constantly failed and not a single packet reaches my end of the tunnel. This is what the looking glasses reported: PING 2001:648:ff0d::1(2001:648:ff0d::1) 32 data bytes From 2001:648:2ffc:1106::2 icmp_seq=0 Destination unreachable: No route From 2001:648:2ffc:1106::2 icmp_seq=1 Destination unreachable: No route From 2001:648:2ffc:1106::2 icmp_seq=2 Destination unreachable: No route From 2001:648:2ffc:1106::2 icmp_seq=3 Destination unreachable: No route --- 2001:648:ff0d::1 ping statistics --- 4 packets transmitted, 0 received, +4 errors, 100% packet loss, time 3011ms PING 2001:648:ff0d::1: 56 data bytes ICMPv6 No Route to Destination from gateway sixxs.grnet.gr (2001:648:2ffc:1106::2) for icmp6 from sun.blazing.de (2a01:30:100a:0:203:baff:fe2d:6efa) to 2001:648:ff0d::1 ICMPv6 No Route to Destination from gateway sixxs.grnet.gr (2001:648:2ffc:1106::2) for icmp6 from sun.blazing.de (2a01:30:100a:0:203:baff:fe2d:6efa) to 2001:648:ff0d::1 ICMPv6 No Route to Destination from gateway sixxs.grnet.gr (2001:648:2ffc:1106::2) for icmp6 from sun.blazing.de (2a01:30:100a:0:203:baff:fe2d:6efa) to 2001:648:ff0d::1 ICMPv6 No Route to Destination from gateway sixxs.grnet.gr (2001:648:2ffc:1106::2) for icmp6 from sun.blazing.de (2a01:30:100a:0:203:baff:fe2d:6efa) to 2001:648:ff0d::1 ICMPv6 No Route to Destination from gateway sixxs.grnet.gr (2001:648:2ffc:1106::2) for icmp6 from sun.blazing.de (2a01:30:100a:0:203:baff:fe2d:6efa) to 2001:648:ff0d::1 ----2001:648:ff0d::1 PING Statistics---- 5 packets transmitted, 0 packets received, 100% packet loss
