EVPN VXLANv6 Overlay with Distributed Anycast Gateway In a BGP EVPN VXLANv6 fabric with Distributed Anycast Gateway, the underlay supports IPv6 transport. The VXLAN tunnels and BGP peering, both support IPv6 addressing. The overlay has both Layer 2 and Layer 3 routes and supports MAC, IPv4 and IPv6 addressing. Distributed Anycast Gateway with VXLANv6 supports Layer 2 bridging, Layer 3 routing within the EVPN fabric, and Layer 3 stitching through Layer 3 border gateway with IPv6 underlay. For Layer 3 routing, both IPv4 and IPv6 overlay prefixes are supported over IPv6 underlay. Figure 2:
BGP EVPN VXLANv6 Fabric with Distributed Anycast Gateway Topology in the figure shows a BGP EVPN VXLANv6 fabric with integrated routing and bridging (IRB) using distributed anycast gateway (DAG). The fabric supports both IPv4 and IPv6 hosts, and IPv6 BGP peering. How to Configure BGP EVPN VXLANv6 This section describes only the changes in the underlay configuration. For the overlay and complete configuration of the fabric, refer How to Configure EVPN VXLAN Layer 2 Overlay Network and Information About EVPN VXLAN Integrated Routing and Bridging .
Configure VXLANv6 for BGP EVPN Fabric with Layer 2 Overlay Implement the following tasks to configure IPv6 underlay for a BGP EVPN VXLAN fabric with Layer 2 overlay.
