Hi<br>
I am using Openstack Juno release to test some basic ipv6. I created a<br>
ipv6 tenant network and subnet with ip6_ra_mode and ipv6_address_mode set<br>
to<br>
DHCPv6 stateful. The instance cannot get the DHCP ip address.<br>
<br>
Reason seems to be that the DHCP advertise message in response to the DHCP<br>
solicit message from the client says no address available<br>
14:14:07.861197 IP6 (hlim 1, next-header UDP (17) payload length: 64)<br>
fe80::f816:3eff:fee2:25ef.dhcpv6-client > ff02::1:2.dhcpv6-server: [udp<br>
sum ok] dhcp6 solicit (xid=172906 (client-ID hwaddr/time type 1 time<br>
454713283 5254005cbf62) (option-request DNS-server DNS-search-list<br>
Client-FQDN SNTP-servers) (elapsed-time 295) (IA_NA IAID:1055008239<br>
T1:3600 T2:5400))<br>
14:14:07.862505 IP6 (class 0xc0, hlim 64, next-header UDP (17) payload<br>
length: 92) fe80::f816:3eff:fe58:88c7.dhcpv6-server ><br>
fe80::f816:3eff:fee2:25ef.dhcpv6-client: [udp sum ok] dhcp6 advertise<br>
(xid=172906 (client-ID hwaddr/time type 1 time 454713283 5254005cbf62)<br>
(server-ID hwaddr/time type 1 time 475357091 fa163e5888c7) (IA_NA<br>
IAID:1055008239 T1:4294967295 T2:4294967295) (status-code no addresses))<br>
<br>
<br>
<br>
<br>
Dnsmasq is launched fine and the hosts file on dhcp seems to be fine<br>
fa:16:3e:e2:25:ef,host-2001-50--6.openstacklocal,[2001:50::6]<br>
<br>
But somehow the DHCP advertise message shows no addresses<br>
