*************************************************************************
Scenario - Providing Carrier Supporting Carrier Multicast MPLS L3 VPN Services Providing
Multicast Traffic between Multicast Server and Clients in Customer Carrier AS 64513
using AS 64514 as Parent Carrier. Both Customer Carrier and Customer Carrier running MPLS
Design Considerations and Soultions: Can use PIM Dense or Sparse Mode. Dense Mode
causes Traffic Flooding whereas Sparse Mode is via Shared Tree where RP is needed
To Provide CSC MPLS VPN Services the we are considering Option Making Customer Carrier a MPLS
VPN Customer for Parent Carrier and using MDT for establishing Multicast across the VPNs in
Parent and Customer Carrrier
ISP A AS used 64514 - Parent carrier
ISP 2 AS used 64513 - Customer Carrier
IGP in ISPA is ISIS
PIM Sparse-Dense-Mode used On ISP Backbone Links and Peering between ISP A & B
IGMP Join-group used to simulate Mutlicast Traffic
224.11.11.11 on CE1A for VRF CEA,224.22.22.22 on CE2A for VRF CEA
