IP multicast boundaries

Configuring multicast boundaries
Multicast boundaries can be configured for IPv4 or IPv6.
To define boundaries for PIM enabled interfaces, enter a commands such as the following.
Brocade(config)# interface ve 40
Brocade(config-vif-40)#ip multicast-boundary MyBrocadeAccessList
Multicast boundaries can be configured for IPv6 as shown in the following.
Brocade(config)# interface ethernet 1/2
Brocade(config-if-e1000-1/2)#ipv6 multicast-boundary MyBrocadeAccessList
Syntax: [no] ip multicast-boundary acl-spec
Syntax: [no] ipv6 multicast-boundary acl-spec
Use the acl-spec parameter to define the number or name identifying an access list that controls
the range of group addresses affected by the boundary.
Use the no ip multicast boundary command to remove the boundary on a PIM enabled interface.
The ACL, MyBrocadeAccessList can be configured using standard ACL syntax. ACLs are described in
Multi-Service IronWare Security Configuration Guide however, some examples of how ACLs can be
used to filter multicast traffic are provided below:
Standard ACL to permit multicast traffic
To permit multicast traffic for group 225.1.0.2 and deny all other traffic, enter the following
command.
Brocade(config)# access-list 10 permit host 225.1.0.2
Brocade(config)# access-list 10 deny any
Extended ACL to deny multicast traffic
To deny multicast data traffic from group 225.1.0.1 and permit all other traffic,
Brocade(config)# access-list 101 deny ip any host 225.1.0.1
Brocade(config)# access-list 101 permit ip any any
Extended ACL to permit multicast traffic
To permit multicast data traffic from source 97.1.1.50 for group 225.1.0.1 and deny all other traffic,
Brocade(config)# access-list 102 permit ip host 97.1.1.50 host 225.1.0.1
Brocade(config)# access-list 102 deny ip any any
Displaying multicast boundaries
To display multicast boundary information, use the show ip pim interface command.
Brocade# show ip pim interface
