The ip address virtual command is generally used to conserve IP addresses in VXLAN deployments and can be used to provide an Anycast gateway. On a VLAN, the same IP address can be configured using this command on multiple VTEPS or on both MLAG devices. Release 4.22.1F introduced [ip address virtual support for PIM and IGMP]. Using that solution, users are required to configure pim ipv4 local-interface on the VLAN interface. PIM and IGMP then borrow the IP address from the local interface specified. Using this configuration, IGMP skips subnet checks for received control messages.

In networks where source and destination of multicast traffic all reside in the same VLAN, IPv6 multicast traffic is flooded to all ports in the VLAN by default. MLD snooping can be enabled to optimize the inefficient transmission, pruning out ports with no receivers.
