Configuring IP Multicast Routing
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 ca ndid ate BSR .
This procedure is optional.
To remove this device as a candidate BSR, use the no ip pim bsr-candidate global configuration
command.
Step5 ip multicast boundary
access-list-number Configure the boundary, specifying the access list you created in Step 2.
Step6 end Return to privileged EXEC mode.
Step7 show running-config Verify your entries.
Step8 copy running-config startup-config (Optional) Save your entries in the configuration file.

Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 ip pim bsr-candidate interface-id
hash-mask-length [priority]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 fir st 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.
Step3 end Return to privileged EXEC mode.
Step4 show running-config Verify your entries.
Step5 copy running-config startup-config (Optional) Save your entries in the configuration file.
