Hi,
I have one trouble about dnsmasq server to assign one IPv6 address for
deployed vm instance. I hope the dnsmasq server can assign one specific
IPv6 address(in dhcp-range) to my deployed VM instance, but always failed,
so who can give me one example about it, or give me some help about it,
thanks very much!
My env as below:
In my host(dnsmasq server 2.66), I have one nic card info called "
tap02f9640d-a7", and this info as below:
tap02f9640d-a7 Link encap:Ethernet HWaddr f2:db:7e:b3:e8:06
inet addr:10.0.3.2 Bcast:10.0.3.255 Mask:255.255.255.0
inet6 addr: fe80::f0db:7eff:feb3:e806/64 Scope:Link
inet6 addr: 2001:db8:dead:beef::2/64 Scope:Global
UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1
RX packets:1599 errors:0 dropped:0 overruns:0 frame:0
TX packets:880 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:216705 (216.7 KB) TX bytes:137894 (137.8 KB)
In /etc/dnsmasq.conf, I have added these options:
dhcp-range=2001:db8:dead:beef::1, 2001:db8:dead:beef::1000, ra-names or
dhcp-range=2001:db8:dead:beef::1,2001:db8:dead:beef::1000, slaac
dhcp-host=openstack,[2001:db8:dead:beef::1]
dhcp-sequential-ip
enable-ra
After this, I run dnsmasq server by "sudo /usr/sbin/dnsmasq -d
--interface=tap02f9640d-a7 --conf-file=/etc/dnsmasq.conf", the instance
will be allocated one IPv6 address (2001:db8:dead:beef:f816:3eff:fe19:963a
), but this IPv6 address is not in dhcp-range, the ipv6 address should be
as like 2001:db8:dead:beef:[1-100], it also my hope.
Simon, can you give me some help about it? thanks in advance.
Thanks & Best Regards
