Define "can not ping back".

I guess you did not try using the scope, eg on my box:

jeroen@purgatory:~$ ip addr sho eth1
3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 08:00:2b:e7:02:b3 brd ff:ff:ff:ff:ff:ff
    inet 213.136.24.43/24 brd 213.154.238.255 scope global eth1
    inet6 2001:7b8:20d:0:290:27ff:fe24:c19f/128 scope global 
       valid_lft forever preferred_lft forever
    inet6 2001:7b8:5:10:f71::2/80 scope global 
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:2bff:fee7:2b3/64 scope link 
       valid_lft forever preferred_lft forever

The neighbour of which is:

jeroen@purgatory:~$ ip -6 nei sho
2001:7b8:5:10:f71::1 dev eth1 lladdr 00:02:4a:8a:a0:1c router nud
reachable
fe80::202:4aff:fe8a:a000 dev eth1 lladdr 00:02:4a:8a:a0:1c router nud
reachable

thus:
jeroen@purgatory:~$ ping6 -I eth1 fe80::202:4aff:fe8a:a000     
PING fe80::202:4aff:fe8a:a000(fe80::202:4aff:fe8a:a000) from
fe80::a00:2bff:fee7:2b3 eth1: 56 data bytes
64 bytes from fe80::202:4aff:fe8a:a000: icmp_seq=1 ttl=64 time=12.3 ms
64 bytes from fe80::202:4aff:fe8a:a000: icmp_seq=2 ttl=64 time=11.0 ms

(Latency introduced by ADSL ;)

Greets,
