Configuring Static SSM Mapping
BEFORE YOU BEGIN

See Information About Source Specific Multicast Mapping, page 683
page 688.

Before you configure SSM mapping, enable IP multicast routing, enable PIM sparse mode, and configure SSM. For
information on enabling IP multicast routing and PIM sparse mode, see
page 689.

Before you configure static SSM mapping, you must configure access control lists (ACLs) that define the group
ranges to be mapped to source addresses.
Purpose
Display the (S, G) channel subscription through IGMPv3.
Display whether a multicast group supports SSM service or whether a
source-specific host report was received.
