The figure below shows the components for a two-tier VCS PIM topology.
FIGURE 59 Two-tier VCS deployment
The following requirements apply to the two-tier-VCS deployment depicted in the figure above:
• Top of rack switches can be Brocade VDX 6710, VDX 6720, VDX 6730, or VDX 8770 models.
However, Top of rack switches are typically only L2-capable when used in this context as part of a
PIM environment, and PIM can be enabled on the Brocade VDX 8770 or VDX 6740 models only.
• Top of rack VCS are typically only L2 capable.
• Top of rack switches must have IGMP-snooping enabled.
• Aggregation-layer VCS must be VDX 8770 or VDX 6740 models only.
• Aggregation-layer switches can be PIM-enabled.
• L3 (VRRP-E and OSPF) can be configured on all interfaces with L3 connectivity to the data-center
core.
• IGMP snooping must be enabled on the aggregation-layer switches.
