PurposeCommand or Action
Use this command to reenable DNS-based SSM
mapping if DNS-based SSM mapping is disabled.
Note
(Optional) Changes the domain prefix used for DNS-based
SSM mapping.
ip domain multicast domain-prefix
Example:
Device(config)# ip domain multicast
ssm-map.cisco.com
Step 5
•
By default, the software uses the ip-addr.arpa domain
prefix.
Specifies the address of one or more name servers to use
for name and address resolution.
ip name-server server-address1
[server-address2...server-address6]
Example:
Device(config)# ip name-server 10.48.81.21
Step 6
--Repeat Step Step 6, on page 273 to configure additional
DNS servers for redundancy, if required.
Step 7
Returns to privileged EXEC mode.end
Example:
Device(config-if)# end
Step 8
Verifies your entries.show running-config
Example:
Device# show running-config
Step 9
(Optional) Saves your entries in the configuration file.copy running-config startup-config
Example:
Device# copy running-config startup-config
Step 10
Configuring Static Traffic Forwarding with SSM Mapping
Perform this task to configure static traffic forwarding with SSM mapping on the last hop router. Static traffic
forwarding can be used in conjunction with SSM mapping to statically forward SSM traffic for certain groups.
When static traffic forwarding with SSM mapping is configured, the last hop router uses DNS-based SSM
mapping to determine the sources associated with a group. The resulting (S, G) channels are then statically
forwarded.
