## Configure Restricted Group Registration

To configure restricted group registration, you must ensure that the following prerequisites are met:

- Interface P3 in switch 1 and switch 2 must be enabled.

- Static multicast entry must be configured.

- Restricted VLAN registration must be configured.

See Default Settings for the topology for this procedure.

1. Configure the VLAN in switch 1.

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/3
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# interface extreme-ethernet 0/4
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# vlan 2
       SEFOS(config-vlan)# ports extreme-ethernet 0/3-4
       SEFOS(config-vlan)# exit
       SEFOS(config)# mac-address-table static multicast 01:02:03:04:05:06 vlan 2 interface extreme-ethernet 0/3
       SEFOS(config)# end

2. Configure the VLAN in switch 2.

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/3
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit

3. Enable restricted group registration in switch 2.

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/3
       SEFOS(config-if)# group restricted enable
       SEFOS(config-if)# end

4. Review the VLAN status.

       SEFOS# show vlan port config port extreme-ethernet 0/3

5. Review the VLAN group entries.

       SEFOS# show mac-address-table
       Vlan    Mac Address         Type     Ports
       -------   ---------------   -------  -------
       1       00:1b:21:53:71:f9   Learnt   Ex0/16
       1       00:21:28:56:d7:ab   Learnt   Ex0/3
       1       00:21:28:56:d7:ac   Learnt   Ex0/4

       Total Mac Addresses displayed: 3

   Note - The group entry (`01:02:03:04:05:06`) is not present in switch 2.
