Configure Optimized Layer 2 Overlay Multicast for IPv6 In addition to the Prerequisites , perform the following steps to configure Optimized Layer 2 Overlay Multicast on the access devices that support IPv6 endpoints. Procedure Configuring Optimized Layer 2 Overlay Multicast Configure Optimized Layer 2 Overlay Multicast for IPv6 Command or Action Purpose Step 3 ip igmp snooping querier Example: Device(config)# ip igmp snooping querier Enables the IGMP snooping querier. Step 4 ip igmp snooping querier version version-num Example: Device(config)# ip igmp snooping querier version 3 Configures the IGMP version which the querier feature uses. By default, IGMP version 2 is configured.
IGMP version 2 extends IGMP functionality with features such as the IGMP leave process, group-specific queries, and an explicit maximum query response time. IGMP version 3 provides functionality for Basic IGMPv3 Snooping Support (BISS), which includes support for the snooping features and for IGMPv3 membership report messages. Step 5 ip igmp snooping querier [max-response-time seconds] [timer expiry seconds] Example: Device(config)# ip igmp snooping querier max-response-time 25 Device(config)# ip igmp snooping querier timer expiry 200 (Optional) Configures the IGMP Snooping Querier parameters. max-response-time configures a maximum response time for snooping query messages.
The range is 1 to 25 seconds. timer expiry sets the length of time until the IGMP querier expires. The range is 60 to 300 seconds. Step 6 end Example: Device(config-evpn)# 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 7
