Problem adding multipe IPv6 on Oracle Linux Server release 8.3

Hello,

I`m trying to configure the NIC ( enp1s0 ) of a Oracle Linux Server to support multiple IPv6 addresses like in CentOS.

So for this I have added in the NIC configuration file ifcfg-enp1s0 the following settings:

Code:IPV6INIT=yes
IPV6ADDR=[IPv6]/64
IPV6ADDR_SECONDARIES="
[IPv6]:100:0:0:0/128
[IPv6]:200:0:0:0/128
[IPv6]:300:0:0:0/128
[IPv6]:0:0:0/128
[IPv6]:0:0:0/128
"
IPV6_DEFAULTGW=fe80::1%enp1s0
IPV6_DEFAULTDEV=enp1s0
Also added the following configuration lines into sysctl.conf file.

Code:net.ipv6.conf.all.accept_ra=2
net.ipv6.conf.enp1s0.accept_ra=2Restarted network and I can ping6 hostnames that have IPv6 enabled.
The problem after restarting the network is that only one IPv6 is added to the internface.
For example on a CentOS Server that is based on RHel is the same configuration and the Secondaries are added on the same interface.

I've also followed the Oracle Linux Docs for IPv6 Configuration but in this case I can't even get the virtual interface up even if I did the exact steps.

What I'm trying to achive is even if I add multiple virtual interfaces is that to assign the IPv6 secondaries to work.
Yes, will be better to add them stacked on the same interface.

Any ideas on how to get to better results?
