Purpose
(Optional) Exits PIM interface configuration mode, and
returns the router to PIM configuration mode.
Exits PIM configuration mode, and returns the router to
global configuration mode.
(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.
(Optional) Permits multicast group 239.1.1.1 for the
candidate group list.
The commands in
Tip
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
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.
