While 4000 VLANS or VNIDs are supported in a Layer 2 context; for VXLAN RIOT, the number of VLANS or VNIDs supported is limited to
1000.
Conguring VXLAN RIOT
Physical Loopback
In order for this conguration to work, the physical loopback ports are required to be in port-channels. There are two types of physical
loopback interfaces: VXLAN Loopback Port and Non-VXLAN Loopback Port. These two port-channels are implicitly made no spanning tree,
so that they do not go into a blocked state if xSTP is enabled.
Internal Loopback
To congure internal loopback port-channels, add free ports in the device as members of a port-channel, say 10, then congure vxlan-
instance 1 loopback. Free ports should be in no shutdown mode.
1 To provision these ports for physical loopback, enter the following command:
Dell(conf-if-po-10)#vxlan-instance 1 [loopback port-channel id]
Where Po-10 is the VXLAN loopback port and Po-20 is the non-VXLAN loopback port.
2 To provision these ports for internal loopback, enter the following command:
Dell(conf-if-po-10)# vxlan-instance 1 loopback
Example for Physical Loopback:
Dell(conf-if-po-10)#vxlan-instance 1 loopback port-channel 20
Example for Internal Loopback:
Dell(conf-if-po-10)#vxlan-instance 1 loopback
VLT Scenario
VXLAN RIOT with physical loopback and internal loopback are supported in a VLT environment.
VXLAN RIOT with Physical Loopback
To enable VXLAN RIOT in a VLT environment, the physical loopbacks are provisioned as VLT port channels with a peering relationship. The
following illustration shows a VLT VXLAN RIOT set up:
