Parameters
tunnel-number: Specifies a tunnel number in the range of 0 to 1023. The tunnel must be a VXLAN tunnel.
flooding-proxy: Enable flood proxy on the tunnel for the VTEP to send flood traffic to the flood proxy
server. The flood proxy server replicates and forwards flood traffic to remote VTEPs.
Usage guidelines
This command assigns a VXLAN tunnel to a VXLAN to provide Layer 2 connectivity for the VXLAN
between two sites. Alternatively, you can use ENDP for automatic VXLAN tunnel assignment.
You can assign multiple VXLAN tunnels to a VXLAN. For a unicast-mode VXLAN, the system floods
unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.
On a VSI, you can enable flood proxy on multiple VXLAN tunnels. The first tunnel that is enabled with
flood proxy works as the primary proxy tunnel to forward broadcast, multicast, and unknown unicast
traffic. Other proxy tunnels are backups, and they do not forward traffic when the primary proxy tunnel
is operating correctly.
To change a flood proxy tunnel for a VXLAN, perform the following tasks:
• Use the undo tunnel command to remove the flood proxy tunnel.
Use the tunnel command to enable flood proxy on another tunnel and assign the tunnel to the
•
VXLAN.
Examples
# Assign VXLAN tunnels 0, 1, and 2 to VXLAN 10000. Enable flood proxy on tunnel 2 when you assign
it to the VXLAN.
