Step Command Remarks
4. Assign a VXLAN tunnel to
the VXLAN.
tunnel tunnel-number
[ flooding-proxy ]
By default, a VXLAN does not contain any
VXLAN tunnels.
For full Layer 2 connectivity in the VXLAN,
make sure the VXLAN contains the VXLAN
tunnel between each pair of sites in the
VXLAN.
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.
Mapping an Ethernet service instance to a VSI
An Ethernet service instance matches a list of VLANs on a site-facing interface. The VTEP assigns
customer traffic from the VLANs to a VXLAN by mapping the Ethernet service instance to a VSI.
When you configure Ethernet service instances on an interface, follow these guidelines:
• The match criterion in each Ethernet service instance on an interface must be unique. For example,
you cannot configure the encapsulation tagged command in one Ethernet service instance if
another Ethernet service instance already contains this command. You cannot use the
encapsulation s-vid vlan-id command to specify the same 802.1Q VLAN ID for any two Ethernet
service instances on the interface.
• An Ethernet service instance can contain only one match criterion. To change the match criterion,
you must remove the original criterion first. When you remove the match criterion in an Ethernet
service instance, the mapping between the service instance and the VSI is removed automatically.
• To forward the multicast traffic from a VLAN on the interface, make sure an Ethernet service instance
contains the VLAN ID. The interface cannot forward a multicast packet that does not match any
Ethernet service instance.
If an Ethernet service instance contains the encapsulation default match criterion, traffic is matched as
follows:
• The service instance matches any frames if it is the only instance on the interface.
• The service instance matches frames that do not match any other service instance if multiple
instances exist on the interface.
To map an Ethernet service instance to a VSI:
