* sorry for the 2 previous schemas, they came out a mess. I hope this one is
understandable.

hi:

I have this 2 boxes set up like this:


2020::2/128		2020::254/128                3030::254/128
192.168.0.2/24		192.168.0.254/24		192.168.30.254/24

+-------+   eth0        eth3  +-------+
|       |========== |       |   eth1
|   A   |                     |   B   | ----
|       |                     |       |
+-------+                     +-------+



   A

# ip r l
192.168.30.254 dev eth0  scope link
192.168.0.0/24 dev eth0  scope link
169.254.0.0/16 dev lo  scope link
127.0.0.0/8 dev lo  scope link

# ip -6 r l
2020::254 dev eth0  metric 1024  mtu 1500 advmss 1440
3030::254 dev eth0  metric 1024  mtu 1500 advmss 1440
(...plus link local and multicast routes)


   B

# ip r l
127.0.0.1 dev lo  scope link
192.168.0.0/24 dev eth3  proto kernel  scope link  src 192.168.0.254
192.168.30.0/24 dev eth1  proto kernel  scope link  src 192.168.30.254

# ip -6 r l
2020::2 dev eth3  metric 1024  mtu 1500 advmss 1440 metric10 64
(...plus link local and multicast routes)

# cat /proc/sys/net/ipv4/ip_forward
1
#cat /proc/sys/net/ipv6/conf/all/forwarding
1


The problem is that i can ping 192.168.30.254 from A, but i can't ping
3030::254 from A, anyone has a clue why this happens? Is there any
feature i need to turn on or anything misconfigured? Why does it work
for IPv4 but not for IPv6?


A -> B

# ping 192.168.30.254
PING 192.168.30.254 (192.168.30.254) 56(84) bytes of data.
64 bytes from 192.168.30.254: icmp_seq=0 ttld time=0.175 ms
64 bytes from 192.168.30.254: icmp_seq=1 ttld time=0.122 ms

#ping6 3030::254
PING 3030::254(3030::254) 56 data bytes
 From ::1 icmp_seq=0 Destination unreachable: Address unreachable
 From ::1 icmp_seq=1 Destination unreachable: Address unreachable
