virtual-network	MAC addresses associated with a Virtual Overlay Network learning domain.
`vn_name`	Name of virtual network whose associated FDB entries need to be cleared.

All dynamic FDB entries are cleared by default.

To clear FDB entries on a given remote endpoint (added to any virtual network):

clear fdb vxlan ipaddress remote_ipaddress {vr vr_name}

To clear FDB entries on a given remote endpoint added to given virtual network:

clear fdb vxlan ipaddress remote_ipaddress {vr vr_name} virtual-network vn_name

To clear all VXLAN FDB entries (clear all entries learned on the access ports and VXLAN tunnels):

clear fdb vxlan

The following example clears any FDB entries associated with VLAN corporate:

clear fdb vlan corporate
