Generating multicast traffic for CCIE R&S Labs
All of us who are practicing CCIE R&S labs faced the same problem - how to generate mcast traffic for the lab setup and verify mcast routing operation. Today I will try to show some ways generate mcast traffic by using very basic topology and verify the network operation. Our lab setup looks like following – Fig – Network setup for mcast routing We have configured the network according to the addressing plan given above. We have enabled mcast routing in all routers. All interfaces of the routers are configured in PIM-SPARSE-DENSE mode. IGP (RIPv2) is also configured to get end-to-end reachablity. For discussion, R2 configuration is given below ip multicast-routing int s2/0 ip pim sparse-dense-mode int s2/0 ip pim sparse-dense-mode int fa1/0 ip pim sparse-dense-mode router rip ver 2 no auto-summary network 0.0.0.0 Our mcast source is SW1 and receiver is SW2 . SW1 will generate mcast traffic for group 224.1.1.1. SW2 will use IGMP to join this group and receive the mcast traffic. Fo
