IPv6 / Prefix Delegation / Radvd
For some time now I've been trying again to get IPV6 up and running with RA advertising under CentOS8 + Networkmanger-master (1.29 copr repository). Sometimes the local interfaces get an IPv6 address, but mosttime they don't. Unfortunately I cannot identify the problem.
What I did:
/etc/NetworkManager/NetworkManager
[main]
dhcp=dhclient
Result in journalctl:
Okt 22 11:51:01 gix dhclient[1121]: PRC: Prefix a:b:c:d::/56 depreferred
(in the log with correct ipv6-prefix)
- The lokal devices modified to ipv6.method = shared
- set the kernel-parameter "accept_ra" = 2 (to all and default)
What additional steps are todo?
I hope to found here any hint. thx.
