NetworkManager support for secondary IPv6 addresses
Last modified: 2016-05-22 19:35:20 EDT
Description of problem: When configuring network devices in an environment where the DHCPv6 server also can provide secondary IPv6 addresses, NetworkManager will only configure the primary IPv6 address. Running dhclient -6 manually configures all the DHCP provided IPv6 addresses. Version-Release number of selected component: NetworkManager-1.0.2-1.fc22.ppc64le dhcp-client-4.3.2-2.fc22.ppc64le How reproducible: Always. *** *** WITH NETWORK MANAGER *** # cat /etc/sysconfig/network-scripts/ifcfg-enp0s1 DEVICE=enp0s1 ONBOOT=yes HWADDR=08:00:00:00:01:30 BOOTPROTO=none IPV4_FAILURE_FATAL=no DHCPV6C=yes # nmcli con up id 'System enp0s1' Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2) # ifconfig enp0s1 enp0s1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 2001:67c:1220:808:a00:ff:fe00:130 prefixlen 64 scopeid 0x0<global> inet6 fe80::a00:ff:fe00:130 prefixlen 64 scopeid 0x20<link> ether 08:00:00:00:01:30 txqueuelen 1000 (Ethernet) RX packets 19964 bytes 1072366 (1.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 92 bytes 9102 (8.8 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 *** *** MANUALLY WITH DHCLIENT (WITHOUT NETWORK MANAGER) *** # dhclient -6 enp0s1 # ifconfig enp0s1 enp0s1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 2001:67c:1220:808:0:30:93e5:83a prefixlen 128 scopeid 0x0<global> inet6 2001:67c:1220:808:a00:ff:fe00:130 prefixlen 64 scopeid 0x0<global> inet6 fe80::a00:ff:fe00:130 prefixlen 64 scopeid 0x20<link> ether 08:00:00:00:01:30 txqueuelen 1000 (Ethernet) RX packets 20779 bytes 1111647 (1.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 106 bytes 10416 (10.1 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

David or Beniamino do we have dhcpv6 networks somewhere in RH?
(In reply to Tomas Pelka from comment #3) > David or Beniamino do we have dhcpv6 networks somewhere in RH? Not inside RH, but the Open Power Hub in Brno have such a setup. I have a VM running there and can help out with any type of testing.
just a remark regarding not inside - I meant, I don't know of any dhcpv6 enabled networks inside RH, at least none with also provides secondary addresses too.
