Configuring VXLAN Tunneling

vxlan flood

This command configures remote VXLAN tunnel endpoint (VTEP) when the
received packet fails bridge table lookup. Use the no form to restore the default
setting.
Syntax
vxlan [vni vni-id] flood { r-vtep ip-address | multicast ipv4-address vlan vid
interface }
no vxlan [vni vni-id] flood { r-vtep ip-address | multicast }
vni-id - A 24-bit segment ID used to identify each VXLAN segment, termed
the VXLAN Network Identifier. The VNI is used in an outer header that
encapsulates the inner MAC frame originated by a virtual machine (VM).
ip-address - The IPv4/v6 address assigned to a remote VTEP. If the egress
port is not found, the packet is encapsulated as a unicast packet and
flooded to all VTEPs on this VNI.
multicast - Multicast is used for carrying unknown destination, broadcast,
and multicast frames.
ipv4-address - Each VTEP VNI joins this multicast group as an IP host
through the IGMP. IGMP joins are used to trigger PIM joins for this group.
vid - The VLAN assigned to this VNI.
interface - The port assigned to this VNI.
ethernet unit/port
unit - Unit identifier. (Range: 1)
port - Port number. (Range: 1-32/54)
Default Setting
None

Command Usage
◆
VTEPs communicate with one another through flooding or multicast within the
specified multicast group.
◆
When a VNI is configured to flood by multicasting, all unknown unicast,
multicast and broadcast packets are transmitted by encapsulating them in
multicast packets.
◆
Each VNI can be assigned to only one VLAN (using the
command); and each VLAN can be assigned a maximum of one VNI. Multiple
remote VTEPs can be configured to flood packets on the same VNI.
