Description: When ASM group filtering is enabled, then for groups in the ASM space, the local router will:

- process received PIM (*,G) Join and (S,G) Join messages only if the group address is included in the standard access list corresponding to the list index value configured for this object, and

- accept (*,G) and (S,G) local membership requests from the MGMD Router component only if the group address is included in the standard access list corresponding to the list index value configured for this object.

In other words, the standard access list is a whitelist of the ASM groups for which DC-PIM is permitted to request traffic.

Note that DC-PIM will never Register-encapsulate multicast data packets for groups that are blocked by this filter. See rlPimTmEntRegSrcAndGrpFilter for additional Register message filtering options.

rlPimTmEntAsmGrpFilter defaults to an empty string, which indicates that no access list is specified.
