HAPTER 17: IP MULTICAST
Examples
When you add an IGMP proxy on an interface, you can allow a single
multicast group or a range of multicast groups to be proxied. An example of
each instance is shown below:
Example 1 — This example shows an IGMP proxy that enables a range of
multicast groups to be proxied:
Group Address — 225.1.1.0
Mask — 255.255.0.0
This enables a proxy range from 225.1.0.0 to 255.1.255.255
Example 2 — This example shows an IGMP proxy that enables a single
multicast group to be proxied:
Group Address — 226.1.1.1
Mask — 255.255.255.255
This enables the interface to proxy the multicast group 226.1.1.1.
Example 3 — This example shows how a more specific IGMP proxy route
takes precedence over a less specific route:
Proxy 1 — 225.4.3.0/225.225.225.0 metric 1 1/1/1
Proxy 2 — 225.4.0.0/225.225.0.0 metric 1 1/2/1
If both proxies are configured and a multicast packet to 225.4.3.1 is
received, the Cuda 12000 proxies to 1/1/1 but if a packet is received with
225.4.5.1, the Cuda 12000 proxies to 1/2/1.
Deleting IGMP Proxies
To delete an IGMP proxy, follow this procedure:
1. In the Summary window, select the interface that includes the proxy you
wish to delete.
2. Click the Proxy tab. The Proxy window appears.
3. Select the IGMP proxy you wish to delete.
4. Click Delete. A window appears to confirm the deletion.
