The (conceptual) table listing the Source List entries corresponding to each interface and multicast group pair on a router. This table includes entries for: - group memberships learned over IGMP/MLD, including those with sources configured using SSM mapping, and - memberships statically configured through mgmdRouterSrcListCfgTable. Each entry will also appear in mgmdRouterPerEntSrcListTable. Note that this table does not include the entity index at the start of the OID. This provides a more flexible lookup, but in a system with many Router entities, the trade-off is that the performance is not as good. See the description of mgmdRouterCacheTable for details. Hence in most cases it is better to use mgmdRouterPerEntSrcListTable instead. This table is not used for IGMP snooping, because a single row in this table would correspond to multiple objects (one per bridge domain). Use mgmdRouterPerEntSrcListTable instead.
