systemd-networkd static IPv6 setup, cant do it.

Hello.

I need to setup a static IPv6 network.
I seem not to be able to do it.

I tried to do it like this:

First I configured the systemd-networkd like so:

[root@jenia]# cat /etc/systemd/network/eth0.network
[Match]
Name=eth0

[Network]
DNS=72.14.179.5
DNS=72.14.188.5
DNS=2600:3c00::2
DNS=2600:3c00::3

[Address]
Address=fe80::abcd:efgh:ijkl:mnop/64 <--------------- this address appears below, in the 'ip -6 addr' output

[Route]
Gateway=fe80::1

Then i did:

[root@jenia]# systemctl restart systemd-networkd
[root@jenia]# systemctl status systemd-networkd 
â systemd-networkd.service - Network Service
   Loaded: loaded (/usr/lib/systemd/system/systemd-networkd.service; enabled)
   Active: active (running) since Wed 2014-07-16 13:49:34 EDT; 5s ago
     Docs: man:systemd-networkd.service(8)
 Main PID: 4429 (systemd-network)
   Status: "Processing requests..."
   CGroup: /system.slice/systemd-networkd.service
           ââ4429 /usr/lib/systemd/systemd-networkd

Jul 16 13:49:34 li428-212.members.linode.com systemd-networkd[4429]: eth0            : gained carrier
Jul 16 13:49:34 li428-212.members.linode.com systemd-networkd[4429]: lo              : gained carrier
Jul 16 13:49:34 li428-212.members.linode.com systemd[1]: Started Network Service.
Jul 16 13:49:34 li428-212.members.linode.com systemd-networkd[4429]: eth0            : link configured

And finally, I saw that it didnt work:

[root@jenia]# ping6 ipv6.google.com -c 3            
PING ipv6.google.com(dfw06s40-in-x06.1e100.net) 56 data bytes

--- ipv6.google.com ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 1999ms

Here is some more infomation about the network:

[root@ jenia]# ip -6 addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2600:3c00::9169:4517:8d82:2ef2/64 scope global noprefixroute dynamic 
       valid_lft 2591981sec preferred_lft 604781sec
    inet6 fe80::abcd:efgh:ijkl:mnop/64 scope link <------------------------------------ this address appears above in the /etc/systemd/network/eth0.network file
       valid_lft forever preferred_lft forever
    inet6 fe80::cdcc:7192:2988:8aee/64 scope link 
       valid_lft forever preferred_lft forever


[root@ jenia]# ip -6 route
2600:3c00::/64 dev eth0  proto kernel  metric 203  mtu 1500
fe80::/64 dev eth0  proto kernel  metric 256 
default via fe80::1 dev eth0  metric 203  mtu 1500


[root@ jenia]# cat /etc/resolv.conf 
domain members.linode.com
nameserver 72.14.179.5
nameserver 72.14.188.5
nameserver 2600:3c00::2
nameserver 2600:3c00::3
options rotate

Maybe someone can help me to setup this IPv6 static network?

Thanks greatly for your time and kind concern.

Re: systemd-networkd static IPv6 setup, cant do it.

I changed the

[Address]
Address=fe80::abcd:efgh:ijkl:mnop/64

to this:

[Address]
Address=2600:3c00::abcd:efgh:ijkl:mnop/64

No effect.

Also see this:

[root@jenia ]# ping6 fe80::1%eth0                        
PING fe80::1%eth0(fe80::1) 56 data bytes
64 bytes from fe80::1: icmp_seq=1 ttl=255 time=0.807 ms
64 bytes from fe80::1: icmp_seq=2 ttl=255 time=0.736 ms
64 bytes from fe80::1: icmp_seq=3 ttl=255 time=0.750 ms
64 bytes from fe80::1: icmp_seq=4 ttl=255 time=0.751 ms
64 bytes from fe80::1: icmp_seq=5 ttl=255 time=0.748 ms
