Multicast Configuration Guide
OL-
Step 7
exit
Example:
RP/0/0/CPU0:router(config-pim-ipv4-if)# exit
(Optional) Exits PIM interface configuration mode, and
returns the router to PIM configuration mode.
Step 8
exit
Example:
RP/0/0/CPU0:router(config-pim-default-ipv4)#
exit
Exits PIM configuration mode, and returns the router to
global configuration mode.
Step 9
{ipv4 | ipv6} access-list name
Example:
RP/0/0/CPU0:router(config)# ipv4
access-list 4
(Optional) Defines the candidate group list to the BSR.
• Access list number 4 specifies the group prefix
associated with the candidate RP address 172.16.0.0.
(See
Step 4).
• This RP is responsible for the groups with the prefix
239.
Step 10
[sequence-number] permit source
[source-wildcard]
or
[sequence-number] permit source-prefix
dest-prefix
Example:
RP/0/0/CPU0:router(config-ipv4-acl)# permit
239.1.1.1 0.255.255.255
(Optional) Permits multicast group 239.1.1.1 for the
candidate group 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 239.1.1.1 0.255.255.255
Step 11
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.
