For IPv4 multicast traffic, refer Topology for Optimized Layer 2 Overlay Multicast Interworking with External Network . Figure 9: Topology for Optimized Layer 2 Overlay Multicast Interworking with External Network for IPv6 Traffic The topology shows an EVPN VXLAN fabric, with two spine switches and three VTEPs, connected to an external network. Multicast traffic source is located in Layer 2 VTEP 1 and receivers are located in Layer 2 VTEP 3, the Centralized Gateway, and also located in the external network. Centralized gateway (CGW) is configured on VTEP 2. VLAN 101 has IGMPv2 and MLD enabled and VLAN 102 has IGMPv3 and MLD Configuring Optimized Layer 2 Overlay Multicast Example 6:
