To achieve a nondisruptive migration, the EVPN VXLAN network should migrate incrementally from IPv4 to IPv6 underlay. During migration, the part of the network that is migrated to IPv6 underlay remains connected with the part of the network that still works with IPv4 underlay.
The incremental migration is achieved by individually making each VTEP dual stack-capable. A dual stack VTEP node has two VTEP addresses (IPv4 and IPv6) associated with the same VXLAN Network Identifier (VNI). During the underlay migration, both these VTEP IP addresses are advertised to peers in a single BGP EVPN dual next-hop update. The receiving nodes in the underlay can choose either IPv4 or IPv6 for traffic forwarding. This ensures connectivity between the IPv4 VTEPs, the dual stack VTEPs and IPv6 VTEPs. After all the VTEPs in the fabric are made dual stack-capable, each VTEP is migrated to IPv6.
