Configuring the Bootstrap Router
This task configures one or more candidate bootstrap routers (BSRs) and a BSR mapping agent. This
task also connects and locates the candidate BSRs in the backbone portion of the network.
For more information about BSR see the “PIM Bootstrap Router” section on page MCC-12.
SUMMARY STEPS
1. configure
2. router pim [address-family {ipv4 | ipv6}]
3. bsr candidate-bsr ip-address [hash-mask-len length] [priority value]
4. bsr candidate-rp ip-address [group-list access-list] [interval seconds] [priority value]
5. interface type interface-path-id
6. bsr border
7. exit
8. exit
9. {ipv4 | ipv6} access-list name
10. [sequence-number] permit source [source-wildcard]
Step 7
[sequence-number] permit source
[source-wildcard]
Example:
RP/0/0/CPU0:router(config-ipv4-acl)# permit
239.1.1.1 0.0.0.0
(Optional) Permits multicast group 239.1.1.1 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 239.1.1.1 0.0.0.0
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.
