Cisco Catalyst 3650 User Manual

PurposeCommand or Action
Exits interface configuration mode and returns to global configuration mode.exit
Example:
Device(config-if)# exit
Step 5
Enters interface configuration mode.
interface type number
Step 6
Example:
Device(config)# interface
gigabitethernet 1/0/0
•
For the type and number arguments, select an interface that is facing
the nondirectly connected hosts.
Enables IGMP report forwarding of proxied (*, G) multicast static route
(mroute) entries.
ip igmp mroute-proxy type number
Example:
Device(config-if)# ip igmp
mroute-proxy loopback 0
Step 7
•
This step is performed to enable the forwarding of IGMP reports to
a proxy service interface for all (*, G) forwarding entries in the
multicast forwarding table.
•
In this example, the ip igmp mroute-proxy command is configured
on Gigabit Ethernet interface 1/0/0 to request that IGMP reports be
sent to loopback interface 0 for all groups in the mroute table that are
forwarded to Gigabit Ethernet interface 1/0/0.
Exits interface configuration mode and returns to global configuration mode.exit
Example:
Device(config-if)# exit
Step 8
Enters interface configuration mode for the specified interface.
interface type number
Step 9
Example:
Device(config)# interface loopback
0
•
In this example, loopback interface 0 is specified.
Configures IGMP helpering for UDLR.ip igmp helper-address udl
interface-type interface-number
Step 10
•
This step allows the downstream device to helper IGMP reports
received from hosts to an upstream device connected to a UDL
Example:
Device(config-if)# ip igmp
associated with the interface specified for the interface-type and
interface-number arguments.
helper-address udl gigabitethernet
0/0/0
•
In the example topology, IGMP helpering is configured over loopback
interface 0 on the downstream device. Loopback interface 0, thus, is
configured to helper IGMP reports from hosts to an upstream device
connected to Gigabit Ethernet interface 0/0/0.
Enables the mroute proxy service.ip igmp proxy-service
