Public bug reported: How to reproduce: ================= On AWS EC2: - launch a CentOS 7.6 instance with IPv4 only - once running: assign an IPv6 from AWS EC2, and reboot the instance - while the instance data is properly populated: the network configuration does not assign the IPv6 to the instance (no connection).
Unsuccessful turnaround attempts: ================================= A) /etc/cloud/cloud.cfg.d/99-ipv6-networking.cfg network: version: 1 config: - type: physical name: eth0 subnets: - type: dhcp6 B) There has been a debate in the CentOS github as to whether AWS was IPv6 RFC compliant, read the entire thread here: https://github.com/coreos/bugs/issues/1828 A solution provided there for Ubuntu cannot be applied on CentOS. ** Affects: cloud-init Importance: Undecided Status: New ** Tags: aws ec2 ipv6 -- You received this bug notification because you are a member of Yahoo!
