Configuring IP Multicast Routing
Configuring IP Multicast Routing
DETAILED STEPS
Command
1. configure terminal
2. access-list access-list-number
deny source [source-wildcard]
3. interface interface-id
4. no shutdown
5. ip multicast boundary
access-list-number
6. end
7. show running-config
8. copy running-config
startup-config
To remove the boundary, use the no ip multicast boundary interface configuration command.
EXAMPLE
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. This procedure is optional.
BEFORE YOU BEGIN
Enable PIM on the interface using the ip pim command as described in the
page 689.
Purpose
Enter global configuration mode.
Create a standard access list, repeating the command as many
times as necessary.

For access-list-number, the range is 1 to 99.

The deny keyword denies access if the conditions are
matched.

For source, enter multicast addresses 224.0.1.39 and
224.0.1.40, which carry Auto-RP information.

(Optional) For source-wildcard, enter the wildcard bits in
dotted decimal notation to be applied to the source. Place
ones in the bit positions that you want to ignore.
Recall that the access list is always terminated by an implicit
deny statement for everything.
Specify the interface to be configured, and enter interface
configuration mode.
Enable the port, if necessary. By default, UNIs and ENIs are
disabled, and NNIs are enabled.
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.
