Multiple address on the sixxs interface

Hello,
I'm trying to give more than one address to my endpoint interface.
So, I start my router (Raspian).
The tunnel stars and everything seem to be ok.
I can ping6 sixxs.net from the router.
I can ping6 the router from an external IPv6 enabled server.
Then, I try add a new address to the sixxs interface wiith "ip addr add 2a01:240:fe00:XXXX::3/64 dev sixxs".
Ifconfig says now :
sixxs Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
adr inet6: fe80::40:fe00:XXXX:2/64 Scope:Lien
adr inet6: 2a01:240:fe00:XXXX::3/64 Scope:Global
adr inet6: 2a01:240:fe00:XXXX::2/64 Scope:Global
After that, I try to ping the new address from the external server but I get this message : "From 2a01:240:fe00:2ec::1 icmp_seq=15 Destination unreachable: No route".
I ran a "tcpdump -i sixxs" while the ping test is still running but I saw no traffic at all. No NDP request, nothing.
Well, I surely made something wrong... Does anybody can explain my mistake ?
Best regards,
Ludovic Martin

A tunnel can only have 1 address, the <tunnelprefix>::2/64. Nothing else.
See also the FAQ that details that only <tunnelprefix>::1 (the PoP) and <tunnelprefix>::2 (your side) of the tunnel prefix are used.
No NDP request, nothing.
It is a tunnel, thus there is no Neighbour Discovery.

Thank you for you answers.
I was trying to do something that tunnels are not designed for :-) I understand better now.
