[release-ocm-2.10] MGMT-17641: Deploy dual stack with IPv6 on top of bond/vlan fails #6235
[release-ocm-2.10] MGMT-17641: Deploy dual stack with IPv6 on top of bond/vlan fails #6235
Conversation
IPv6 L2 connectivity check uses nmap. nmap uses NDP (Network Discovery Protocol) to check L2 connectivty to IPv6 hosts. There are cases that NDP response does not arrive or it is not captured by nmap which means that the system assumes there is no connectivity to the host. However, there might be L3 connectivity (ping) to the same host. So change adds fallback for IPv6 L2 connectivity. In case there is failure in L2 connectivity to IPv6 host and success in L3 connecivity to the same host, the host is assumed connected on L2, providing that the remote address is part of the L2 subnet being checked.
