[ovs-discuss] Failed to change ipv6 dst address (ipv6_dst)

[陈维烨]

Hi,
   I am trying to forward ipv6 messages through openvswitch on RHEL6, and
meet some problems.
   The added flow is as following:

   ovs-ofctl mod-flows br0 "table=0, in_port=73, dl_type=0x86dd,
ipv6_dst=2001:1b70:200:1027::183:46, action=mod_dl_dst:00:0C:29:44:55:67,
set_field:2001:1b70:200:1027::183:200->ipv6_dst, normal"

   Nothing happens, but one warning message in the log:
   2014-02-20T15:52:37.741Z|00917|dpif(miss_handler)|WARN|system at ovs-system:

set(eth(src=f6:a9:3b:be:17:31,dst=00:0c:29:44:55:67)),set(ipv6(src=2001:1b70:200:1027::183:20,dst=2001:1b70:200:1027::183:200,label=0,proto=58,tclass=0,hlimit=64,frag=no)),18,11,21,1,pop_vlan,22,push_vlan(vid=107,pcp=0),12
failed (Invalid argument) on packet
icmp6,metadata=0,in_port=0,dl_vlan=107,dl_vlan_pcp=0,dl_src=f6:a9:3b:be:17:31,dl_dst=c2:1c:d1:bb:f3:04,ipv6_src=2001:1b70:200:1027::183:20,ipv6_dst=2001:1b70:200:1027::183:46,ipv6_label=0x00000,nw_tos=0,nw_ecn=0,nw_ttl=64,icmp_type=128,icmp_code=0,nd_sll=00:00:00:00:00:00,nd_tll=00:00:00:00:00:00

   I have tried similar fuction on IPv4, it seems ok.
   For IPv6, have I mis-configured the flow?
