Example 2: Configuring Optimized Layer 2 Overlay Multicast with Ingress Replication for IPv4 and IPv6 This example shows how to configure Optimized Layer 2 Overlay Multicast across the Layer 2 overlays in an EVPN VXLAN fabric that has ingress replication enabled in the underlay. The example configuration is for both IPv4 and IPv6 multicast traffic. For IPv4 multicast traffic, refer Topology for Optimized Layer 2 Overlay Multicast with Ingress Replication for IPv4 . Figure 5: Topology for Optimized Layer 2 Overlay Multicast with Ingress Replication for IPv6 Traffic The topology shows an EVPN VXLAN network with the source connected to Layer 2 VTEP 1 and receivers connected to Layer 2 VTEP 3.
A Centralized Gateway is configured on VTEP 2. VLAN 101 has MLD exclude mode and VLAN 102 has MLD include mode. The following tables provide sample configurations for IPv4 and IPv6 multicast traffic for the devices in this topology: Configuring Optimized Layer 2 Overlay Multicast Example 2: Configuring Optimized Layer 2 Overlay Multicast with Ingress Replication for IPv4 and IPv6 Configuring Optimized Layer 2 Overlay Multicast 26
