IP Multicast Group Table

The IP multicast group table specifies the egress ports for Layer 2 and Layer 3 multicast traffic groups. To make more space available in the IP multicast group table, you can do the following:
  • Leave IP multicast compression enabled (it is enabled by default). This allows multiple L3 hash entries to share the same IP multicast group entry if the the egress list is the same.
  • Use the following I/O modules, which provide higher capacity tables:
    • BlackDiamond 8900 xl-series modules
    • BlackDiamond 8900-G96T-c
