Configuring Multicast Boundaries

An access list is used to define boundaries for PIM enabled interfaces.

This task requires a standard or extended access list to be created to filter multicast traffic. A standard access list is defined in the steps. Other access list example configurations follow this task.

This task assumes that PIM routing is enabled for the interface used in this task.

Enter global configuration mode.
```
device# configure terminal
```

To permit multicast traffic for group 225.1.0.2, enter the following command.
```
device(config)# ip access-list standard 10 
device(config-std-ipacl-10)# permit host 225.1.0.2
```

To deny all other traffic, enter the following command.
```
 
device(config-std-ipacl-10)# deny any
device(config-std-ipacl-10)# exit
```

Enter virtual Ethernet interface mode.
```
device(config)# interface ve 40
```

Configure multicast boundaries for VE 40 using access list 10.
```
device(config-vif-40)# ip multicast-boundary 10
```

The following example creates standard access list 10 to permit multicast traffic for group 225.1.0.2 and deny all other traffic. Access list 10 is used to define multicast boundaries for PIM-enabled interfaces.

device# configure terminal
device(config)# ip access-list standard 10 
device(config-std-ipacl-10)# permit host 225.1.0.2
device(config-std-ipacl-10)#  deny any
device(config-std-ipacl-10)# exit
device(config)# interface ve 40
device(config-vif-40)# ip multicast-boundary 10
