Conguring VXLAN RIOT
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 to act like edge
ports, so that they do not go into a blocked state if xSTP is enabled.
To provision these ports, 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.
Dell(conf-if-po-10)#vxlan-instance 1 loopback port-channel 20
VLT Scenario
VXLAN RIOT with physical loopback is supported in a VLT environment.
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:
In this topology, P2 and P3 in VTEP 1 are VLT port-channels with corresponding VLT peer LAGs being P2 and P3 in VTEP 2. Similarly, P6
and P7 in VTEP 3 are VLT port-channels with corresponding VLT peer LAGs being P6 and P7 in VTEP 4.
NOTE
: P2, P3, P6, and P7 can be a single port or multi-port port-channels that are VLT port-channels.
NOTE: The VLT VXLAN conguration for RIOT deviates from the standard VLT behavior when these physical loopbacks are
provisioned as VLT port-channels.
