IP Address Groups

X Family LSM User’s Guide V 2.5.1 153

The device supports two multicast protocols. You can configure an IP interface with either or both

protocols.

• IGMP — Internet Group Management Protocol, used by hosts to define multicast group

membership. Multicast groups are identified by special IP addresses.

IGMP must be enabled on all IP interfaces that are directly connected to clients using multicast

traffic.

• PIM-DM — Protocol Independent Multicast-Dense Mode routing protocol, used for multicast

routing between remote sites. PIM-DM is also used to support site-to-site NBX conference calls.

PIM-DM must be enabled on all IP interfaces that multicast data will travel through to/from the

multicast clients. This includes the GRE and IP interfaces.

Enable Multicasting on an IP Interface

STEP 1

From the LSM menu, select Network > Configuration > IP Interfaces.

STEP 2

On the IP Interfaces page, click the Create IP Interface button or select the Edit icon for the

interface that you want to edit.

STEP 3

On the IP Interfaces (Create/Edit) page, click the Enable IGMP and/or Enable PIM-DM

check box to enable multicast routing.

STEP 4

Click Save.

Click Cancel to return to the IP Interfaces page without saving the changes.

STEP 5

Enable Firewall Rules to allow PIM-DM and/or IGMP to/from this-device for the relevant

zones.

After configuring the multi-cast routing options, verify the IGMP and/or PIM-DM options have been

enabled globally. For details, see the following topics:

• “IGMP Setup” on page 163

• “PIM-DM Setup” on page 165

IP Address Groups

IP Address Groups allow you to associate a selection of IP addresses with a name that can be used in

place of the specific IP addresses. IP Address Groups save time when configuring features on the device

since you can apply the same parameters to all IP addresses in the group rather than configuring each

address separately.

Note Firewall rules must be established to allow PIM-DM and IGMP to be

passed through the firewall between each set of security zone pairs that the

multicast traffic must traverse. This includes between virtual zones such as a VPN

zone, and this-device.
