*************************************************************************
Scenario - Providing Inter-AS Multicast MPLS L3 VPN Services Providing Multicast
Traffic between Multicast Server in AS 64513 and Multicast Clients in AS 64514
and vice-versa
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 Inter-AS MPLS VPN Services the we are considering Option for creating GRE Tunnel
between the PEs attached to CEs and running PIM over GRE Tunnels
CAVEATS: This solution is not scalable as for multiple sites attached to different PEs
Full meshed GRE Tunnels needs to be created between PEs with n(n-1)/2 scalability issue
Static mroutes need to defined for interested source-destination networks for multicast
traffic flow
ISP 1 AS used 64513
ISP 2AS used 64514
IGP in ISP2 is ISIS
PIM Sparse-Dense-Mode used On ISP Backbone Links and Peering between ISP 1 & 2
via PE12 and PE22
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
