Flow caching is enabled for multicast traffic

Supported devices have flow cache support for the following multicast traffic:

• IPv4 and IPv6 multicast
• GRE encapsulated multicast traffic (PIM MVPN, rosen 6 MVPN)
• Multicast traffic encapsulated in MPLS (BGP MVPN)
• Tunnel as multicast outgoing interface (OIF)

The multicast flows are stored in the same flow table as unicast flows. Tunnel flows consume two flow entries. To support flow caching, the maximum values are:

• Size of flow table -- 1 million entries (unicast and multicast)
• Number of multicast flows -- 32,768
• Number of replications -- 16 If multicast traffic exceeds the limits, packets are sent to microcode for processing.
