Campus Network Scenario

• Between Subscriber (SS1) and Switch (SW1)
• Each VLAN segment is assigned a unique VID
• E.g. Dept 1 packets are tagged w/ VID300
• Each VID has a CIR (minimum bit rate)
• For each VLAN segment
• A virtual group is defined as a multicast domain
• E.g. Group I for Dept 1 at Site 1 and Site 2
• Each group has a multicast CIR
• Within each virtual group
• VID can differ at each site
• E.g. Group II for Dept 2
• packet VID400 at Site 1
• packet VID700 at Site 2
• Data between Dept 1 2
• Through Router
• Layer 3 connectivity only

• Dept 1 packets tagged with VID 300
• Dept 2 packets tagged with VID 400
