Hello,
I think I have ARP problem with IPv6.
IPv6 is working on HN.
VE can ping HN.
VE can not ping gateway of HN.
Container:
VE:~# route -6
Kernel IPv6 routing table
Destination Next Hop Flag Met Ref Use If
2000::/3 :: U 1024 0 0 venet0
fe80::/64 :: U 256 0 0 venet0
::/0 :: !n -1 1 14214 lo
::1/128 :: Un 0 1 4 lo
::1/128 :: Un 0 1 0 lo
2001:XXX:1::c8/128 :: Un 0 1 209 lo
ff00::/8 :: U 256 0 0 venet0
::/0 :: !n -1 1 14214 lo
I cant ping gateway of HN:
VE:~# ping6 2001:XXX:1::1
PING 2001:XXX:1::1(2001:XXX:1::1) 56 data bytes
--- 2001:XXX:1::1 ping statistics ---
166 packets transmitted, 0 received, 100% packet loss, time 165020ms
With tcpdump I can see that the router asking for ip of VE, 2001:XXX:1::c8
14:15:28.515495 IP6 2001:XXX:1::c8 > 2001:XXX:1::1: ICMP6, echo request, seq 1, length 64
14:15:28.516387 IP6 2001:XXX:1::1 > ff02::1:ff00:c8: ICMP6, neighbor solicitation, who has 2001:XXX:1::c8, length 32
14:15:29.515277 IP6 2001:XXX:1::c8 > 2001:XXX:1::1: ICMP6, echo request, seq 2, length 64
14:15:29.516413 IP6 2001:XXX:1::1 > ff02::1:ff00:c8: ICMP6, neighbor solicitation, who has 2001:XXX:1::c8, length 32
Im running CentOS with kernel 2.6.18-92.1.13.el5.028stab059.6.
