Network Topology Example
Figure 69 shows a basic IP multicast MLS example network topology.
Figure 69 Example Network: Basic IP Multicast MLS
The network is configured as follows:
• There are three VLANs (IP subnetworks): VLANs 10, 20, and 30.
• The multicast source for group G1 belongs to VLAN 10.
• Hosts A, C, and D have joined IP multicast group G1.
• Port 1/2 on the MMLS-SE is connected to interface fastethernet2/0 on the MMLS-RP.
• The link between the MMLS-SE and the MMLS-RP is configured as an ISL trunk.
• The subinterfaces on the router interface have these IP addresses:
– fastethernet2/0.10: 10.1.10.1 255.255.255.0 (VLAN 10)
– fastethernet2/0.20: 10.1.20.1 255.255.255.0 (VLAN 20)
– fastethernet2/0.30: 10.1.30.1 255.255.255.0 (VLAN 30)
