Bug 1910165: [baremetal] Correctly handle multiple ipv6 addresses on interface #2312
Bug 1910165: [baremetal] Correctly handle multiple ipv6 addresses on interface #2312
Conversation
Generally speaking there should only be one address configured per interface. However, in some ipv6 environments a node may get an address from both DHCP and SLAAC. In this case, we need to make sure that the ipv6 DHCP to static dispatcher script can handle the inputs it gets. Previously, the lease time check would get back a single string with multiple values. This caused the if to always fail, which meant we would do static configuration even if the DHCP lease was not infinite. This change further filters the lease time query to ensure it only returns the value for the specific DHCP address in question. It also improves the address assignment logic to ensure that we get the correct address no matter how many are present on the interface.
