A hash bucket in the L3 table has been exceeded and the specified IPv6 multicast (S,G) forwarding entry could not be added to the hardware. The L3 table is shared by IPv4/v6 multicast and IPv4/v6 unicast host entries. The specified (S,G) multicast stream will be slowpath forwarded.
"debug hal show forwarding distributions" can be used to view hash bucket distributions for the available hashing algorithms. "show forwarding configuration" will display the configured and currently running hash algorithm. In order to change the algorithm, use "configure forwarding hash-algorithm [crc16 | crc32]". A system reboot is required for this command to take effect.
