The network has fixed IPv4 address, and automatic acquired IPv6 address. Does anyone have an idea how to setup? Thanks a lot!
I didn't use NetworkManager. The following is my setting, but it does not work 🙁
/etc/sysconfig/network:
NETWORKING=yes
HOSTNAME=desk.myname.ca
NETWORKING_IPV6=yes
IPV6FORWARDING=yes
IPV6_AUTOCONF=yes
/etc/sysconfig/network-scripts/ifcfg-eth0 :
DEVICE=eth0
TYPE="Ethernet"
UUID=29b0480a-83aa-4124-ab27-01dda940afv3
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPADDR=214.52.131.212
GATEWAY=214.52.137.1
NETMASK=255.255.255.0
DNS1=214.52.101.101
DNS2=214.52.101.100
NAME="System eth0"
HWADDR=49:73:E6:CC:6A:26
IPV6INIT=yes
IPV6_AUTOCONFIG=yes
I could not get the a global IPV6 address, as shown by the output of ifconfig:

In order to do SLAAC, you have to have a router that's sending Router Advertisements (RA), to provide the network prefix and prefix length. That will also have the default gateway.
Something, somewhere on the local subnet needs to send the RAs. Usually its the router, but there are some tools to have a Linux (or BSD) box send the RAs on behalf of the local router, if it' not able (like some home routers).
Also, make sure that you are accepting the RAs. See
net.ipv6.conf.default.accept_ra
net.ipv6.conf.all.accept_ra
and make sure they are set to 1
