'No route to host' again

I know this error is discussed in other threads, but I couldn't find a solution that works for me. I'm using kernel 2.4.20-20.7 (Redhat Linux 7.3) compiled with IPv6, when i try to set up the tunnel it shows an error 'No route to host' when setting up the route:

[root@sonic src]# ip tunnel add sixxs mode sit local 62.221.212.120 remote 213.197.27.252 [root@sonic src]# ip link set sixxs up [root@sonic src]# ip link set mtu 1280 dev sixxs [root@sonic src]# ip tunnel change sixxs ttl 64 [root@sonic src]# ip -6 addr add 2001:838:300:a8::1/64 dev sixxs [root@sonic src]# ip -6 ro add default via 2001:838:300:a8::1 dev sixxs RTNETLINK answers: No route to host [root@sonic src]#

The route to the IPv4 endpoint is fine:

[root@sonic src]# traceroute 213.197.27.252 traceroute to 213.197.27.252 (213.197.27.252), 30 hops max, 38 byte packets 1 62.221.212.1 (62.221.212.1) 0.443 ms 0.411 ms 0.368 ms 2 62.221.199.1 (62.221.199.1) 0.528 ms 3.953 ms 0.728 ms 3 81.17.32.178 (81.17.32.178) 0.686 ms 0.727 ms 0.675 ms 4 ams-ix.concepts.nl (195.69.144.64) 0.989 ms 0.908 ms 1.158 ms 5 tunnelserver.concepts-ict.net (213.197.27.252) 1.035 ms 1.324 ms 1.165 ms [root@sonic src]#

When pinging to the IPv6 endpoint however, replies come from localhost (::1):

[root@sonic src]# ping6 2001:838:300:a8::1 PING 2001:838:300:a8::1(2001:838:300:a8::1) from ::1 : 56 data bytes 64 bytes from 2001:838:300:a8::1: icmp_seq=1 ttl=64 time=0.029 ms

I was hoping someone could help me with this.

ip -6 addr add your_ipv6_endpoint dev sixxs ip -6 ro add default via sixxs_ipv6_endpoint dev sixxs

You are forgetting to add "Your IPv6 Endpoint", see Linux Setup FAQ Thus 8<-------- [root@sonic src]# ip -6 addr add 2001:838:300:a8::1/64 dev sixxs -------->8 Should be: [root@sonic src]# ip -6 addr add 2001:838:300:a8::2/64 dev sixxs You are now adding the POP's IPv6 address (and thus your gateway) on your local box...
