IP Multicast in a Wireless LAN

IP Multicast WLAN Configuration

Source For:

        • 239.255.0.1

        • 239.192.248.1

          Low-rate stream

Campus

VLAN 200 10.1.200.x

In this configuration:

L3-SWITCH connects to the campus network and the Cisco Aironet 350 Access Point (10.1.200.100).

The VLAN 200 interface on L3-SWITCH has the IP address of 10.1.200.1 and is the interface that provides the boundary for IP multicast.

The laptop computer (10.1.200.101) has a Cisco Aironet 350 PC Card and is running the IP/TV Viewer software.

Below is the configuration is for L3-SWITCH.

interface Vlan200 description WLAN VLAN ip address 10.1.200.1 255.255.255.0 ip pim sparse-mode ip multicast boundary IPMC-WLAN ! ip access-list standard IPMC-WLAN permit 239.192.248.1

Enables PIM on the interface. Boundary refers to named ACL “IPMC-WLAN” and controls multicast forwarding AND IGMP packets.

Permits low-rate stream (239.192.248.1).

See Verification and Testing for steps to verify this configuration.

Controlling IP Multicast in a P2P WLAN using Bridges

The same boundary that was deployed in the AP scenario is used with the bridge scenario. Figure 3-2 shows the topology for a WLAN using a bridge for a Point-to-Point (P2P) connection. The IP/TV server

        • (10.5.10.22)

          is sourcing the same groups as in the previous example:

        • 239.255.0.1

          is a high-rate (1.4 Mbps) video stream.

        • 239.192.248.1

          is a low-rate (100 Kbps) video stream.
