Juniper JUNOSE 11.2.X MULTICAST ROUTING

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.
IP and VLAN Statistics
Use the show vlan subinterface command to display statistics for a VLAN interface
configured over port 8. For more information, see Monitoring Ethernet Interfaces in the
JunosE Physical Layer Configuration Guide.
Use the show ip interface command to display statistics for an IP interface configured
over port 8. For more information, see Monitoring IP in the JunosE IP, IPv6, and IGP
Configuration Guide.
Multicast traffic redirected by the hardware multicast packet replication feature is
displayed in the statistics for the IP or VLAN interface over port 8, not the original IP or
VLAN interface over the physical port.
The statistics for the IP or VLAN interface over port 8 reflect the number of packets that
passed through this interface destined for the hardware multicast packet replication
hardware. These statistics have no direct correlation to the number of packets being
transmitted from any of the physical ports.
