Customizing Multicast Routing
Configuring a Multicast Group
Multicast groups are lists of access rules that define which multicast addresses are part of the group. A
multicast group can contain a single multicast address or a range of multicast addresses. Use the Add
Multicast Group dialog box to create a new multicast group rule. Use the Edit Multicast Group dialog
box to modify an existing multicast group rule.
To configure a multicast group, perform the following steps:
In the main ASDM window, choose Configuration > Device Setup > Routing > Multicast > PIM >
Step 1
Rendezvous Points.
The Rendezvous Point pane appears. Click the group that you want to configure.
Step 2
The Edit Rendezvous Point dialog box appears.
Step 3
Click the Use this RP for the Multicast Groups as specified below radio button to designate the
Step 4
multicast groups to use with specified RP.
Click Add or Edit.
Step 5
The Add or Edit Multicast Group dialog box appears.
From the Action drop-down list, choose Permit to create a group rule that allows the specified multicast
Step 6
addresses, or choose Deny to create a group rule that filters the specified multicast addresses.
In the Multicast Group Address field, type the multicast address associated with the group.
Step 7
From the Netmask drop-down list, choose the network mask for the multicast group address.
Step 8
Click OK.

The Add/Edit/Insert Neighbor Filter Entry dialog box appears. The Add/Edit/Insert Neighbor Filter
Entry dialog box lets you create the ACL entries for the multicast boundary ACL. You can also delete a
selected PIM neighbor from this table.
Choose the interface name from the Interface Name drop-down list.
Step 3
From the Action drop-down list, choose Permit or Deny for the neighbor filter ACL entry.
