Configuring IP Multicast Routing
Configuring IP Multicast Routing
To configure IP multicast routing, perform the following procedure, beginning in global configuration
mode:
Monitoring and Verifying IP Multicast Operation
After IP multicast routing is configured, you can monitor and verify its operation by performing the
commands listed in Table 10-10, from privileged EXEC mode.
Command Purpose
Step 1
Router(config)# ip multicast-routing
Enables IP multicasting on the ML-Series card.
Step 2
Router(config)# interface
type number
Enters interface configuration mode to configure
any interface.
Step 3
Router(config-if)# ip pim {dense-mode |
sparse mode | sparse-dense-mode}
Runs IP multicast routing on each interface on
which you enter this command. You must indicate
dense mode, sparse mode, or sparse-dense mode.
Step 4
Router(config)# ip pim rp-address
rendezvous-point ip address
Configures a rendezvous point for the multicast
group.
Step 5
Router(config-if)# end
Returns to privileged EXEC mode.
Step 6
Router# copy running-config startup-config
(Optional) Saves your configuration changes to
NVRAM.
Table 10-10 IP Multicast Routing Show Commands
Command Purpose
Router# show ip mroute
Shows the complete multicast routing table and the combined
statistics of packets processed.
Router# show ip pim neighbor
When used in EXEC mode, lists the PIM neighbors
discovered by the Cisco IOS software.
Router# show ip pim interface
Displays information about interfaces configured for PIM.
Router# show ip pim rp
When used in EXEC mode, displays the active rendezvous
points (RPs) that are cached with associated multicast routing
