Chapter 38 Configuring IP Multicast
Configuring IP Multicast Routing
Step 9
Switch(config)# ip pim send-rp-announce
{interface-type interface-number | ip-address}
scope ttl-value [group-list access-list]
[interval seconds] [bidir]
Sends RP announcements out all PIM-enabled interfaces.
• Perform this step on the RP router only.
• Use the interface-type and interface-number arguments
to define which IP address is to be used as the RP
address.
• Use the ip-address argument to specify a directly
connected IP address as the RP address.
Note If the ip-address argument is configured for this
command, the RP-announce message is sourced by
the interface to which this IP address is connected
(that is, the source address in the IP header of the
RP-announce message is the IP address of that
interface).
• This example shows that the interface is enabled with a
maximum of 31 hops. The IP address by which the
router wants to be identified as RP is the IP address
associated with loopback interface 0. Access list 5
describes the groups for which this router serves as RP.
Step 10
Switch(config)# ip pim send-rp-discovery
[interface-type interface-number] scope
ttl-value [interval seconds]
Configures the router to be an RP mapping agent.
• Perform this step on the RP router only.
• Use the optional interface-type and interface-number
arguments to define which IP address is to be used as
the source address of the RP mapping agent.
• Use the scope keyword and ttl-value argument to
specify the Time-to-Live (TTL) value in the IP header
of Auto-RP discovery messages.
• Use the optional interval keyword and seconds
argument to specify the interval at which Auto-RP
discovery messages are sent.
Note Lowering the interval at which Auto-RP discovery
messages are sent from the default value of 60
seconds results in more frequent floodings of the
group-to-RP mappings. In some network
environments, the disadvantages of lowering the
interval (more control packet overhead) may
outweigh the advantages (more frequent
Requirementsgroup-to-RP mapping updates).
• The example shows limiting the Auto-RP discovery
messages to 31 hops on loopback interface 1.
