## Configure the IP-Based Multicast Forwarding Mode

If you have questions about the topology used in this section, see Flow-Based Configuration Example. For the default settings, see Default Settings.

1. On DUT1, configure the multicast forwarding mode for IGS as IP-based.

       SEFOS# configure terminal
       SEFOS(config)# snooping multicast-forwarding-mode ip

2. Disable GMRP.

       SEFOS(config)# set gmrp disable

3. Enable IGS.

       SEFOS(config)# ip igmp snooping

4. Configure `VLAN 2` in the switch.

       SEFOS(config)# vlan 2

5. Configure the static VLAN entry (`VLAN 2`) with the required ports.

       SEFOS(config-vlan)# ports extreme-ethernet 0/1-5
       SEFOS(config-vlan)# exit

6. Enter the Interface Configuration mode for Gigabit Ethernet interface `0/1`.

       SEFOS(config)# interface extreme-ethernet 0/1

7. Set the PVID as `VLAN 2`.

       SEFOS(config-if)# switchport pvid 2

8. Bring up the interface.

       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit

9. Enter Interface Configuration mode for Gigabit Ethernet interface `0/2`.

       SEFOS(config)# interface extreme-ethernet 0/2

10. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

11. Bring up the interface.

        SEFOS(config-if)# no shutdown
        SEFOS(config-if)# exit

12. Enter Interface Configuration mode for Gigabit Ethernet interface `0/3`.

        SEFOS(config)# interface extreme-ethernet 0/3

13. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

14. Bring up the interface.

        SEFOS(config-if)# no shutdown
        SEFOS(config-if)# exit

15. Enter Interface Configuration mode for Gigabit Ethernet interface `0/4`.

        SEFOS(config)# interface extreme-ethernet 0/4

16. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

17. Bring up the interface.

        SEFOS(config-if)# no shutdown
        SEFOS(config-if)# end

18. Enter Interface Configuration mode for Gigabit Ethernet interface `0/5`.

        SEFOS(config)# interface extreme-ethernet 0/5

19. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

20. Bring up the interface.

        SEFOS(config-if)# no shutdown
        SEFOS(config-if)# end

21. Review the IGS-related configurations.

        SEFOS# show ip igmp snooping globals

        Snooping Configuration
        -----------------------------
        IGMP Snooping globally enabled
        IIGMP Snooping is operationally enabled
        IGMP Snooping Enhanced mode is disabled
        Transmit Query on Topology Change globally disabled
        Multicast forwarding mode is IP based
        Proxy globally disabled
        Proxy reporting globally enabled
        Filter is disabled
        Router port purge interval is 125 seconds
        Port purge interval is 260 seconds
        Report forward interval is 5 seconds
        Group specific query interval is 2 seconds
        Reports are forwarded on router ports
        Group specific query retry count is 2
        Multicast VLAN disabled
        Leave config level is Vlan based

22. Review the VLAN information.

        SEFOS# show vlan id 2

        Vlan database-------------------Vlan ID                 : 2Member Ports            : Ex0/1, Ex0/2, Ex0/3, Ex0/4, Ex0/5Untagged Ports          : NoneForbidden Ports         : NoneName                    :Status                  : Permanent----------------------------------------------------

23. Send V2 join messages for group MG1 (`227.1.1.1`) from host A.
24. Send V3 join messages for group MG1 (`227.1.1.1`) and SRC B (`12.0.0.50`) from host C.
25. Send multicast data packets for MG1 (`01:00:5e:01:01:01`) from SRC A (`12.0.0.40`) and SRC B (`12.0.0.50`).
26. Review the forwarding database.

        SEFOS# show ip igmp snooping forwarding-database

        Vlan     Source Address    Group Address        Ports ------ ---------------------- --------------------  -------    2      12.0.0.40         227.1.1.1           Ex0/2    2      12.0.0.50         227.1.1.1           Ex0/2, Ex0/4

    Host A receives multicast data from both of the sources. However, host C receives multicast data only from SRC B.
