Configuring VXLANs
Feature compatibility requirements
When you use VXLAN in conjunction with other features, follow these restrictions and guidelines:
•
If multiple VXLAN tunnels share a transport-facing interface, make sure the VXLAN tunnels use
the same VLAN interface for forwarding.
•
EVB and VXLAN cannot work together. Do not configure both features on an interface. For
more information about EVB, see
EVB Configuration Guide .
•
Do not configure EVI or MPLS settings on VXLANs. For more information about EVI and MPLS,
see
EVI Configuration Guide and MPLS Configuration Guide .
•
A site-facing interface does not support Layer 3 multicast if Ethernet service instances are
configured on the interface.
•
You must disable the spanning tree protocol ( undo stp enable ) on a site-facing interface if
Ethernet service instances are configured on it.
•
For a multicast-mode VXLAN to forward traffic correctly, do not configure VXLANs or VXLAN
tunnels on transport network devices.
VXLAN configuration task list
Tasks at a glance Remarks
(Required.) Creating a VXLAN on a VSI N/A
(Required.) Configuring a VXLAN tunnel N/A
(Required.) Assigning VXLAN tunnels to a VXLAN
To extend a VXLAN to remote
sites, you must assign VXLAN
tunnels to the VXLAN.
(Required.) Mapping an Ethernet service instance to a VSI
Perform this task to assign
customer traffic to VXLANs.
(Optional.) Managing MAC address entries N/A
(Optional.) Configuring a multicast-mode VXLAN
By default, the VTEP floods
VXLAN traffic in unicast mode.
If the network is multicast
dense, configure the VTEP to
flood VXLAN traffic in multicast
mode.
(Optional.) Confining unknown-unicast floods to the local site N/A
(Optional.) Configuring the destination UDP port number of VXLAN
packets
N/A
(Optional.) Configuring VXLAN packet check
Perform this task to check the
802.1Q VLAN tags in the inner
Ethernet header of incoming
VXLAN packets.
(Optional.) Enabling ARP flood suppression N/A
