Your corporate network equipment currently includes a 4006 Core switch with an L3 module for VLAN routing and a Cisco 2600 external access router. Connected to your corporate network via a 128k leased line is your branch network that includes a 2600 Cisco WAN router and a 2600XL switch for local access. Your corporate network is segmented into four functional VLANs for better network management. VLANs include “Accounting”, “Marketing” and “Engineering” for the users and “default” used for the native VLAN network management. Inter-VLAN routing has been implemented using the Layer-3 routing switch module.

Scenario Current Environment Your corporate network equipment currently includes a 4006 Core switch with an L3 module for VLAN routing and a Cisco 2600 external access router. Connected to your corporate network via a 128k leased line is your branch network that includes a 2600 Cisco WAN router and a 2600XL switch for local access. Your corporate network is segmented into four functional VLANs for better network management. VLANs include Accounting Marketing and Engineering for the users and default used for the native VLAN network management. Inter-VLAN routing has been implemented using the Layer-3 routing switch module. No VLAN-trunking to the external router has been configured. Enhancement Your LAN and WAN connections function well and your company executives have now decided to implement an IP TV Multicast system throughout the LAN to include the access switch connected to the branch router over the WAN. The branch LAN will facilitate only audio streams to reduce WAN congestion until a faster WAN connection can be purchased. The implementation calls for the IP TV server to be connected to VLAN10 and clients connected to any Ethernet segment on the corporate LAN and branch office LAN as illustrated in the diagram. PIM-Sparse Mode has been selected as the multicast routing protocol for corporate WAN multicast traffic. The corporate 2600 router has been selected as the PIM-Sparse RP point device.
