PIM Sparse
Table 258 shows the information displayed for each software data structure listed in the output of
the show ip pim resource command.
NOTE
When the product of the number of active PIM interfaces multiplied by the number of multicast
streams exceeds the total number of MLL, the CLI displays the message, “MLL pool out of memory”.
NOTE
The total number of MLL available changes according to the hardware configuration.

Mils
In Layer 3 multicast, this refers to the Multicast Linked List that contains information on where
(S,G) gets forwarded. Each (S,G) entry requires a single MLL entry to forward traffic to all
physical, untagged ports. Also, one MLL entry is required per VLAN that has tagged outbound
ports. There can be up to 1024 MLL entries.
