Configuring IP Multicast Routing
Command
Step 5
ip multicast boundary
access-list-number
Step 6
end
Step 7 show running-config
Step 8 copy running-config startup-config
To remove the boundary, use the no ip multicast boundary interface configuration command.
This example shows a portion of an IP multicast boundary configuration that denies Auto-RP
information:
Switch(config)# access-list 1 deny 224.0.1.39
Switch(config)# access-list 1 deny 224.0.1.40
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# ip multicast boundary 1
Configuring Candidate BSRs
You can configure one or more candidate BSRs. The devices serving as candidate BSRs should have
good connectivity to other devices and be in the backbone portion of the network.
Beginning in privileged EXEC mode, follow these steps to configure your switch as a candidate BSR.
This procedure is optional.
Command
Step 1 configure terminal
Step 2
ip pim bsr-candidate interface-id
hash-mask-length [priority]
Step 3 end
Step 4 show running-config
Step 5
copy running-config startup-config
To remove this device as a candidate BSR, use the no ip pim bsr-candidate global configuration
command.

Purpose
Configure the boundary, specifying the access list you created in Step 2.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Configure your switch to be a candidate BSR.
• For interface-id, enter the interface on this switch from which the
BSR address is derived to make it a candidate. This interface must
be enabled with PIM. Valid interfaces include physical ports, port
channels, and VLANs.
For hash-mask-length, specify the mask length (32 bits maximum)
•
that is to be ANDed with the group address before the hash function
is called. All groups with the same seed hash correspond to the same
RP. For example, if this value is 24, only the first 24 bits of the group
addresses matter.
• (Optional) For priority, enter a number from 0 to 255. The BSR with
the larger priority is preferred. If the priority values are the same,
the device with the highest IP address is selected as the BSR. The
default is 0.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
