Running two S4 cores, each with a VRRP instance to 25 individual closet switch stacks. I am enabling IGMP on each network in each core that we need multicast traffic extended to. There are 3 networks in each closet (student/employee/ipt) which will total 75 networks in each core with IGMP enabled. The.show ip pim command will show 75 pim neighbors I suspect. Does this sound correct? Anyone have any comments on this config. Pim SM will be used.thnks in advancewalt
