Nokia supports IGMP in an IP cluster as part of the new support for PIM, both dense-mode and
sparse-mode, in an IP cluster. The support for IGMP in an IP cluster ensures synchronization of
IGMP state from master to members when a new node running PIM joins the cluster. For more
information about PIM and IP Clustering, see “PIM” on page 370 and “IP Clustering
Description” on page 207.
Configuring IGMP
1. Complete “Ethernet Interfaces” for the interface.
2. Configure a multicast routing protocol, such as PIM or DVMRP.
The IGMP feature supports IP multicast groups on a network and functions only in
conjunction with a multicast routing protocol to calculate a multicast distribution tree. For
more information on multicast routing protocols supported by IPSO, see “PIM” on page 370
or “DVMRP” on page 390
3. Click IGMP under Configuration > Routing Configuration in the tree view.
4. Complete the following steps for each interface on which you enabled a multicast routing
protocol.
5. Click the appropriate Version button to enable either version 1 or 2; then click Apply.
The default is version 2
