PurposeCommand or Action
Configures a source as part of a set of sources that
map SSM groups described by the specified access
list.
ssm map static source-address access-list
Example:
RP/0/RSP0/CPU0:router(config-igmp)# ssm map static
Step 3
232.1.1.1 mc2
—
Repeat Step 3, on page 54 as many times as you have source
addresses to include in the set for SSM mapping.
Step 4
commit
Step 5
(Optional) Queries the mapping state.
show igmp [vrf vrf-name] ssm map [group-address][detail]
Step 6
Example:
RP/0/RSP0/CPU0:router# show igmp vrf vrf20 ssm map
•
When you provide one address for mapping,
you receive the state for that address alone.
•
When you provide no address for mapping,
you receive the state for all sources.
232.1.1.1
232.1.1.1 is static with 1 source
or
RP/0/RSP0/CPU0:router# show igmp vrf vrf20 ssm map
232.1.1.0 is static with 3 sources
232.1.1.1 is static with 1 source
Configuring a Static RP and Allowing Backward Compatibility
When PIM is configured in sparse mode, you must choose one or more routers to operate as a rendezvous
point (RP) for a multicast group. An RP is a single common root placed at a chosen point of a shared distribution
tree. An RP can either be configured statically in each router, or learned through Auto-RP or BSR.
This task configures a static RP. For more information about RPs, see the Rendezvous Points, on page 14.
For configuration information for Auto-RP, see the Configuring Auto-RP to Automate Group-to-RP Mappings,
on page 56.
