Implementing Inter-AS MVPN Using GRE Tunnel Between PE LAB

Confgiguration Guidelines
*************************************************************************

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

Implementing Inter-AS MVPN Using Option B MP-eBGP with BGP MDT SAFI LAB

Confgiguration Guidelines
*************************************************************************

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 B whereby we are using MP-eBGP
between ASBRs.

Inter-AS Multicast is achieved by utilising BGP MDT SAFI and estabilishing MDT Tunnels between PEs.




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

Implementing Inter-AS MVPN Using Option A Back-to-Back VRF with BGP MDT SAFI LAB

Confgiguration Guidelines
*************************************************************************

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 Cconsiderations 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 A whereby we are using back-to-back
VRFs between ASBRs.

Inter-AS Multicast is achieved by utilising BGP MDT SAFI and estabilishing MDT Tunnels between PEs.

Caveats: This solution for Inetr-AS MVPN requires a dedicated Physical Interface or Subinterfaces between ASBRs
per VRF


ISP 1 AS used 64513
IGP in ISP1 is OSPF with passive-interfaces for non-ospf Interfaces
ISP 1 AS used 64514
IGP in ISP1 is OSPF with passive-interfaces for non-ospf Interfaces


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 CE1A for VRF CEA;224.33.33.33 on CE2A
for VRF CEA and 224.44.44.44on CE2A for VRF CEB
