Preserving 802.1 p value across VXLAN tunnels
The 802.1p QoS marking preservation is supported over the VXLAN tunnel. The 802.1p priority is carried over from the VXLAN tunnel to
the remote VTEP—VXLAN tunnel endpoint. The packets egress out to the correct queue based on the priority value. In such a scenario, if
there is any congestion in the queue, the system generates a pause. The network port should be a vlan for priority to be carried by the
vxlan outer header.
Routing in and out of VXLAN tunnels
VXLAN provides a way to extend a VLAN over a Layer3 tunnel (VXLAN tunnel) across data centers.
This functionality can also be extended one step further by enabling routing from a VLAN on one data center to a dierent VLAN on
another data center. This scheme to route in and out of tunnels (RIOT) requires setting up of hardware VTEPs that are capable of routing
over a VXLAN tunnel using a physical loopback conguration.
Physical Loopback for VXLAN RIOT
The following topology shows how VXLAN RIOT can be achieved using physical loopbacks. Two port-channels, vxlan and non-vxlan
loopback port-channel, are created in the device. Interface connected at one end of the physical loopback cable is/are added as member of
the non-vxlan loopback port-channel (P2/P6) and other end interfaces as a member of vxlan loopback port-channel (P3/P7).
