Configuring Auto-RP to Automate Group-to-RP Mappings
This task configures the Auto-RP mechanism to automate the distribution of group-to-RP mappings in
your network. In a network running Auto-RP, at least one router must operate as an RP candidate and
another router must operate as an RP mapping agent.
For more information about Auto-RP, see the “Auto-RP” section on page MCC-12.
SUMMARY STEPS
1. configure
2. router pim [address-family ipv4]
3. auto-rp candidate-rp type instance scope ttl-value [group-list access-list-name] [interval
seconds]
4. auto-rp mapping-agent type number scope ttl-value [interval seconds]
5. exit
6. ipv4 access-list name
7. [sequence-number] permit source [source-wildcard]
Step 7
[sequence-number] permit source
[source-wildcard]
Example:
RP/0/0/CPU0:router(config-ipv4-acl)# permit
239.1.1.0 0.0.255.255
(Optional) Permits multicast group 239.1.1.0 0.0.255.255
for the “rp-access” list.
Tip The commands in Step 6 and Step 7 can be
combined in one command string and entered from
global configuration mode like this: ipv4 access-list
rp-access permit 239.1.1.0 0.0.255.255.
Step 8
end
or
commit
Example:
RP/0/0/CPU0:router(config-ipv4-acl)# end
or
RP/0/0/CPU0:router(config-ipv4-acl)#
commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
– Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
– Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
– Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
