Juniper JUNOSE 11.1.X MULTICAST ROUTING, Configuration Manual

Page: 46 / 270

■
Use to set the IGMP version (1, 2, or 3) for the interface or specify a passive
interface with only multicast-data-forwarding capability (passive).
■
Example
host1:boston(config-if)# ip igmp version passive
■
Use the no version to set the version to the default, IGMPv2.
■
See ip igmp version.
ip multicast ioa-packet-replication
■
Use to configure hardware multicast packet replication on port 8 of a high-density
Ethernet module.
■
Example
host1(config-if)# ip multicast ioa-packet-replication gigabitEthernet 3/8.1
■
Use the no version to disable hardware multicast packet replication.
■
See ip multicast ioa-packet-replication.
ip unnumbered
■
Use to configure an unnumbered IP interface.
■
This command enables IP processing on an interface without assigning an explicit
IP address to the interface.
■
You must specify an interface location, which is the identifier of another interface
on which the router has an assigned IP address. This interface cannot be another
unnumbered interface.
■
Example
host1(config-if)# ip unnumbered loopback 10
■
Use the no version to disable IP processing on the interface.
■
See ip unnumbered.
Monitoring Hardware Multicast Packet Replication
This section describes how to monitor hardware multicast packet replication.
Port Statistics
Use the show interfaces gigabitEthernet command to display port statistics for port
8. For port 8, queue statistics have no direct relationship to any of the 8 ports because
each packet transmitting through the queue can be sent through 1 or more of the 8
physical ports. For more information, see
Monitoring Ethernet Interfaces in the JUNOSe
Physical Layer Configuration Guide .
