Chapter 1 Configuring IP Multicast Routing
Configuring IP Multicast Routing
Configuring Static Traffic Forwarding with SSM Mapping
Use static traffic forwarding with SSM mapping to statically forward SSM traffic for certain groups.
Beginning in privileged EXEC mode, follow these steps to configure static traffic forwarding with SSM
mapping:
Step 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.
Step 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.
Step 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.
Step 6
Repeat Step 5 to configure additional
DNS servers for redundancy, if required.
Step 7
end Return to privileged EXEC mode.
Step 8
show running-config Verify your entries.
Step 9
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface type number Select an interface on which to statically forward traffic for a multicast
group using SSM mapping, and enter interface configuration mode.
Note Static forwarding of traffic with SSM mapping works with either
DNS-based SSM mapping or statically configured SSM
mapping.
Step 3
ip igmp static-group group-address
source ssm-map
Configure SSM mapping to statically forward a (S, G) channel from the
interface.
Use this command if you want to statically forward SSM traffic for
certain groups. Use DNS-based SSM mapping to determine the source
addresses of the channels.
Step 4
show running-config Verify your entries.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
