Configure Proxy Reporting in Flow-Based Configurations

Language:

When proxy reporting is enabled, the switch generates reports and forwards them to the router based on the available host information. If you have questions about the topology used in this section, see Flow-Based Configuration Example. For the default settings, see Default Settings.

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

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

Disable GMRP.
```
SEFOS(config)# set gmrp disable
```

Enable IGS.
```
SEFOS(config)# ip igmp snooping
```

Enable proxy reporting.

SEFOS(config)# ip igmp snooping proxy-reporting

Configure VLAN 2 in the switch.
```
SEFOS(config)# vlan 2
```

Configure the static VLAN entry (VLAN 2) with the required ports.
```
SEFOS(config-vlan)# ports extreme-ethernet 0/1-4
```

Configure the static router port as P2 for the VLAN.

SEFOS(config-vlan)# ip igmp snooping mrouter extreme-ethernet 0/2
SEFOS(config-vlan)# exit

Enter the Interface Configuration mode for Gigabit Ethernet interface 0/1.
```
SEFOS(config)# interface extreme-ethernet 0/1
```

Set the PVID as VLAN 2.
```
SEFOS(config-if)# switchport pvid 2
```

Bring up the interface.

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

Enter Interface Configuration mode for Gigabit Ethernet interface 0/2.
```
SEFOS(config)# interface extreme-ethernet 0/2
```

Set the PVID as VLAN 2.
```
SEFOS(config-if)# switchport pvid 2
```

Bring up the interface.

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

Enter Interface Configuration mode for Gigabit Ethernet interface 0/3.
```
SEFOS(config)# interface extreme-ethernet 0/3
```

Set the PVID as VLAN 2.
```
SEFOS(config-if)# switchport pvid 2
```

Bring up the interface.

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

Enter Interface Configuration mode for Gigabit Ethernet interface 0/4.
```
SEFOS(config)# interface extreme-ethernet 0/4
```

Set the PVID as VLAN 2.
```
SEFOS(config-if)# switchport pvid 2
```

Bring up the interface.

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

Review the IGS-related configurations.

SEFOS# show ip igmp snooping globals

Review the database information for VLAN 2.

Review the multicast router information.

SEFOS# show ip igmp snooping mrouter

Send an IGMP V2 report from host B and host C.
Only one of the reports should be forwarded to the router port on host A.
