Chapter 34 Configuring IP Unicast Routing
Configuring Stub Routing
To disable PIM stub routing on an interface, use the no ip pim passive interface configuration command.
In this example, IP multicast routing is enabled, Switch A PIM uplink port 25 is configured as a routed
uplink port with spare-dense-mode enabled. PIM stub routing is enabled on the VLAN 100 interfaces
and on Gigabit Ethernet port 20 in Figure 34-4:
Switch(config)# ip multicast-routing distributed
Switch(config)# interface GigabitEthernet0/25
Switch(config-if)# no switchport
Switch(config-if)# ip address 3.1.1.2 255.255.255.0
Switch(config-if)# ip pim sparse-dense-mode
Switch(config-if)# exit
Switch(config)# interface vlan100
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface GigabitEthernet0/20
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface vlan100
Switch(config-if)# ip address 100.1.1.1 255.255.255.0
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface GigabitEthernet0/20
Switch(config-if)# no switchport
Switch(config-if)# ip address 10.1.1.1 255.255.255.0
Switch(config-if)# ip pim passive
Switch(config-if)# end
To verify that PIM stub is enabled for each interface, use the show ip pim interface privileged EXEC
command:
Switch#show ip pim interface
Address Interface Ver/ Nbr Query DR DR
Mode Count Intvl Prior
3.1.1.2 GigabitEthernet0/25 v2/SD 1 30 1 3.1.1.2
100.1.1.1 Vlan100 v2/P 0 30 1 100.1.1.1
10.1.1.1 GigabitEthernet0/20 v2/P 0 30 1 10.1.1.1
Use these privileged EXEC commands to display information about PIM stub configuration and status:
• show ip pim interface displays the PIM stub that is enabled on each interface.
• show ip igmp detail displays the interested clients that have joined the specific multicast source
group.
• show ip igmp mroute verifies that the multicast stream forwards from the source to the interested
clients.
Step 4
end Return to privileged EXEC mode.
Step 5
show ip pim interface Display the PIM stub that is enabled on each interface.
Step 6
show running-config Verify your entries.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
