Configure Optimized Layer 2 Overlay Multicast Interworking Optimized Layer 2 Overlay Multicast Interworking supports the following scenarios: • Optimized Layer 2 Multicast across Layer 2 Overlays within the same fabric domain • Optimized Layer 2 Overlay Multicast handoff with IP Multicast external network Before You Begin 1. Before you configure the interworking scenarios, ensure that you set up the centralized gateway by performing all the steps described in Configuring EVPN VXLAN Integrated Routing and Bridging using Centralized Default Gateway . 2.
Enable Optimized Layer 2 Multicast on the centralized gateway by performing all the configurations described earlier in this document, under Configure Optimized Layer 2 Multicast in EVPN VXLAN Layer 2 Overlay . Enable Layer 3 Multicast on Centralized Gateway Follow these steps to enable Layer 3 Multicast on the Centralized Gateway: Procedure Configuring Optimized Layer 2 Overlay Multicast Configure Optimized Layer 2 Overlay Multicast Interworking Command or Action Purpose Step 3 ipv6 mld snooping Example: Device(config)# ipv6 mld snooping Enables the MLD snooping. Step 4 ipv6 mld snooping querier Example: Device(config)# ipv6 mld snooping querier Enables the MLD snooping querier.
Step 5 end Example: Device(config)# end Returns to privileged EXEC mode. Command or Action Purpose Step 1 enable Example: Device> enable Enables privileged EXEC mode. Enter your password, if prompted. Step 2 configure terminal Example: Device# configure terminal Enters global configuration mode. Configuring Optimized Layer 2 Overlay Multicast 8
