When the rdisc6 utility is available probe for router advertisement. configure eni and rhel-netscripts interfaces to do IPv6 address configuration according to the flags in the RA recived from the router. The systemd service file timeout is DIB_DHCP_TIMEOUT * 2, so that DHCPv4 can timout, and dhcpv6 run before the service times out. Retries are commented in dhclient.conf, without it we end up trying DIB_DHCP_TIMEOUT * 60 before the client move on to IPv6. WHEN: Stateful address conf. : No Stateful other conf. : No THEN: Do not run dhclient at all, autoconfiguration via SLAAC only. WHEN: Stateful address conf. : No Stateful other conf. : Yes THEN: Run "dhclient -6 -S", The ``-S`` option makes the dhcp client not request an address, only other options such as DNS servers and NTP servers from DHCPv6 server. WHEN: Stateful address conf. : Yes Stateful other conf. : Yes THEN: The dhcp client should request an address _and_ other options such as DNS servers and NTP servers from DHCPv6 server. NOTE: No IPv6 support added for suse-netscripts Closes-Bug: 1754219 Change-Id: Icdc79875c33f894ab7eaec8afdfb33a731efff99 |

=================== dhcp-all-interfaces =================== Autodetect network interfaces during boot and configure them for DHCP The rationale for this is that we are likely to require multiple network interfaces for use cases such as baremetal and there is no way to know ahead of time which one is which, so we will simply run a DHCP client on all interfaces with real MAC addresses (except lo) that are visible on the first boot. On non-Gentoo based distributions the script /usr/local/sbin/dhcp-all-interfaces.sh will be called early in each boot and will scan available network interfaces and ensure they are configured properly before networking services are started. On Gentoo based distributions we will install the dhcpcd package and ensure the service starts at boot. This service automatically sets up all interfaces found via dhcp and/or dhcpv6 (or SLAAC). Environment Variables --------------------- DIB_DHCP_TIMEOUT :Required: No :Default: 30 :Description: Amount of time in seconds that the systemd service(or dhclient) will wait to get an address. Should be increased in networks such as Infiniband. :Example: DIB_DHCP_TIMEOUT=300
