Specifies a virtual IPv4 or IPv6 address for the VR instance. For an owner, the virtual IP must be one of the IP addresses configured on the interface for that VR. For a standby, the virtual IP must match the virtual IP of the owner. The owner and the standbys using a given virtual IP must all belong to the same network or subnet. For IPv6, VR's first address should be link local address. After the primary link local IPv6 address is configured on the VR, user can add the global IPv6 addresses. This column, also specifies the interface's IP address to designate as the source for VRRP advertisements from the VR. By default primary IP address of real interface is used as source for VRRP advertisements. Source IP configuration parameter is for IPv4 only. IPv6 doesn't have a source IP address configuration parameter. For IPv6, the source IP address is the link-local address of the real interface over which the packet is transmitted.
