VXLAN Routing on 7280E, 7500R and 7280R Platforms

The 7500 and 7280 switch series platforms have previously supported VXLAN bridging, which enables stretching of Layer 2 domains across an Layer 3 IP Cloud. In EOS-4.18.0F, VXLAN routing is introduced on these platforms, which provides the capability to route between these stretched Layer 2 domains. In this release, only IPv4 unicast routing is supported in the overlay. In particular, VXLAN Routing is only supported in the Direct Routing mode, where every host is directly attached in the overlay to every VTEP in the network. This requires all VXLAN SVIs for the overlay subnets to be configured on all VTEPs....
