Configuring IP Multicast Routing
Configuring IP Multicast Routing
BEFORE YOU BEGIN
 See Information About Source Specific Multicast Mapping, page 683 and SSM Mapping Configuration Guidelines,
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 Configuring Basic Multicast Routing,
page 689.
 Before you can configure and use SSM mapping with DNS lookups, you must be able to add records to a running
DNS server. If you do not already have a DNS server running, you need to install one.
You can use a product such as Cisco Network Registrar. Go to this URL for more information:

DETAILED STEPS
EXAMPLE
The following example shows how to configure DNS-based SSM mapping:
Switch(config)# ip igmp ssm-map enable
Switch(config)# ip name-server 10.0.0.0
Switch(config)# end
Command Purpose
1. configure terminal Enter global configuration mode.
2. ip igmp ssm-map enable Enable SSM mapping for groups in a configured SSM range.
3. ip igmp ssm-map query dns (Optional) Enable DNS-based SSM mapping.
By default, the ip igmp ssm-map command enables
DNS-based SSM mapping. Only the no form of this command
is saved to the running configuration.
Note: Use this command to re-enable DNS-based SSM
mapping if DNS-based SSM mapping is disabled.
4. ip domain multicast domain-prefix (Optional) Change the domain prefix used by the switch for
DNS-based SSM mapping.
By default, the switch uses the ip-addr.arpa domain prefix.
5. ip name-server server-address1
[server-address2...
server-address6]
Specify the address of one or more name servers to use for
name and address resolution.
6. Repeat Step 5 to configure
additional DNS servers for
redundancy, if required.

7. end Return to privileged EXEC mode.
8. show running-config Verify your entries.
9. copy running-config
startup-config
(Optional) Save your entries in the configuration file.
