This feature adds the ability for an L3 default gateway TEP in a Centralized Gateway topology to advertise its SVI virtual IP addresses to VARP MAC bindings and primary addresses to System MAC bindings using EVPN type-2 routes for EVPN VXLAN overlays. Two new commands, redistribute router-mac virtual-ip[next-hop vtep primary] and redistribute router-mac system ip are introduced to enable the redistributions. This would help the L2 TEP on the network to learn the default gateway IP without flooding an ARP request for the gateway IP. This feature is only intended for Centralized Gateway Topologies.

In EVPN VXLAN context, binding a VRF to a VNI usually consumes a dynamic VLAN as shown in the following sample CLI configuration. The usable range of dynamic VLANs is from 1 to 4094, which is also shared by other features such as internal VLANs. The document describes the extended VLAN support for EVPN VXLAN, which increases the number of usable dynamic VLANs. The extended VLAN range is from 4101 to 8191.
