Scenario - Providing Inter-AS Multicast Services Providing Multicast Traffic between Multicast Server
in AS 64513 and Multicast Client in AS 64514 and vice-versa.
Also preventing RFP Failure for the Multicast Source with the Help of Multicast BGP when the
Multicast Traffic Flow Path is different from the Unicast IPv4 Path fir the Sources.
Also using Source based Blackholing for Smurf Attacks at PE ROuter and BGP Trigered Remote
Blackholing on PE Routers to Prevent Smurf Attacks
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 Multicast the ASBRs peering via Unicast IPv4 should run
MSDP between them to join the Register Messages with the IGMP-Join messages in respective ASes.
Also to have no interference between RPs in the diferent ASes using the Multicast Boundary at the
ASBR Peerings denying 224.0.1.39/40 and allowing rest
There should be Separate RPs in the different Autonomous Systems and independent of each other.Can use
either Static RP,Auto-RP or Bootstrap Router
To Prevent RPF Failure on Multicast source when the Multicast Tree Path and IPv4 Unicast path are different
Using Multicast BGP in individual ASes and between ASBRs. Announcing the Multicast Source under the Multicast IPv4
Family peering using Network Statement and Propagating it further to different AS
The Multicast BGP ROute will be preferred over IPv4 Unicast ROute for RPF Check
For Preventing Smurf Attacks via SOurce based Blackholing ,creating Static Routes for the Sources to Next Hop pointing
to Null 0and redistributing it to Peers inside AS via IBGP
For Preventing Smurf Attach via BGP Trigered Remote Blackholing making the Customer tag and send packets
with the Community which can be matched at ISP PE and set to next hop as a Null ROute.
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
EBGP used within ASes
Customer Routers have default route to ISP PEs.
PIM Sparse-Mode used between PE-CE , On ISP Backbone Links and Peering between ISP 1 & 2
via PE12 and PE22
RP Selected via Bootstrap Router on PE12 and PE22 and propogated in the AS
No PIM used between ISP1 and ISP 2 Peering between P1 and P2 (IPv4 Unicast Peering)
IGMP Join-group used to simulate Mutlicast Traffic
224.22.22.22 on CE2A and 224.33.33.33 on CE1A
224.66.66.66 on PE12 Lo0 to Simulate traffic inside AS 64513
224.55.555.55 on PE22 Lo0 to Simulate traffic inside AS 64514
On CE1A used Lo0 and Lo1 to generate Smurf Trafic Source.
For Lo0 used BGP Trigered Blackholing by Tagging Lo0 IP Block with Commuity 64513:999
which is matched and accpeted by PE11 and Set the Next hop as 192.168.1.254. The Route for 192.168.1.254 is a Host Null Route
Thus causing blockholing and propagating this Information to other PEs via IBGP
For Lo1 used Source Based Blackholing by creating Static Route for Lo1 IP Block on PE11 pointing to 192.168.1.254.The Route for
192.168.1.254 is a Host Null Route Thus causing blockholing and propagating this Information to other PEs via IBGP
Done Extended Ping on CE1A and CE2A to Multicast Groups with Source Interface as Peering with ISP and
Source Address as the Interface Address
