Figure 90 Constraining PIMv2 BSR Messages
EXAMPLE
The following example configures the interface to be the PIM domain border:
interface ethernet 1
ip pim bsr-border
Defining the IP Multicast Boundary
You define a multicast boundary to prevent Auto-RP messages from entering the PIM domain. You create an access list
to deny packets destined for 224.0.1.39 and 224.0.1.40, which carry Auto-RP information. This procedure is optional.
BEFORE YOU BEGIN
Review the Information About PIM, page 677 and the Guidelines and Limitations, page 686.
Command Purpose
1. configure terminal Enter global configuration mode.
2. interface interface-id Specify the interface to be configured, and enter interface
configuration mode.
3. no shutdown Enable the port, if necessary. By default, UNIs and ENIs are
disabled, and NNIs are enabled.
4. ip pim bsr-border Define a PIM bootstrap message boundary for the PIM domain.
Enter this command on each interface that connects to other
bordering PIM domains. This command instructs the switch to
neither send or receive PIMv2 BSR messages on this interface
as shown in Figure 90 on page 705.
5. end Return to privileged EXEC mode.
6. show running-config Verify your entries.
7. copy running-config
