VXLAN on VLT
VLT peers are two nodes in the network that are loosely coupled. It provides high availability to the other ends. VXLAN on VLT provides
resiliency to the servers connected to southbound port-channels and VTEPS connected through L3 cloud to northbound interfaces. As
gateway IP address configuration on both peers is the same, remote VTEP’s view it as a single node. Packets from remote VTEP’s can
land on any node, either VLT primary or secondary. Southbound interfaces are connected via port channels. Even if a port-channel
member connected to one peer is down, the server can send/receive traffic through the other VLT peer.
The figure below shows the topology for a data-center interconnect, in which static VXLAN is used for linking geographically dispersed
data centers. VXLAN tunnels are used to communicate across the data centers. VXLAN on VLT provides high availability to the L3
network and to the servers connected via LAG.
