Example 1: Configuring Optimized Layer 2 Overlay Multicast for IPv4 with Ingress Replication This example shows how to configure Optimized Layer 2 Multicast across Layer 2 overlays in an EVPN VXLAN fabric that has ingress replication enabled in the underlay. Figure 4: Topology for Optimized Layer 2 Overlay Multicast for IPv4 Traffic with Ingress Replication The topology shows an EVPN VXLAN network with the source connected to Layer 2 VTEP 1 and a receiver connected to Layer 2 VTEP 3. Centralized Gateway is configured on VTEP 2. VLAN 101 has IGMPv2 and VLAN 102 has IGMPv3 enabled. The following tables provide sample configurations for the devices in this topology:
