Wrong ipv6 prefixlenght with stateful DHCPv6
Hello, I have a VM with the following NetworkManager on CentOS 7.5:
[root@szombi ~]# rpm -qa | grep NetworkManager NetworkManager-1.12.0-10.el7_6.x86_64
Maybe I configure something wrong but I see next:
5: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether fa:16:3e:a1:25:50 brd ff:ff:ff:ff:ff:ff inet6 fd00:16::10a/128 scope global noprefixroute dynamic valid_lft 5131sec preferred_lft 4831sec inet6 fe80::f816:3eff:fea1:2550/64 scope link noprefixroute valid_lft forever preferred_lft forever
The strange thing is for me noprefixroute and /128. It must be /64. If i use only the default network scripts the address ended with /64 and the other VMs on the network are reachable (and there isn't noprefixroute flag) so maybe I missconfigured something for NetworkManager. (from the OpenStack site we are using stateful routers). I attach the entire nmcli c show command output and the ifcfg file what I use. I really appreciate if someone can say something what should I check or anything useful because I'm little lost in this topic and.
