Configuring Multicast Interoperation with N7K-F132-15 Modules
Product
Cisco NX-OS

Prerequisites for Multicast Interoperation

For multicast interoperation, you must have at least one module of the following series in the Cisco Nexus
7000 Series chassis, as well as a valid license installed:
• M Series
• N7K-F132-15

Guidelines and Limitations

Multicasting requires you to have interfaces from both the M-Series and the N7K-F132-15 modules in the
same VDC.

Configuring Layer 3 Multicast Using a Mixed Chassis

You can configure a Layer 3 gateway in a chassis with N7K-F132-15 and M-Series modules, by using the
proxy routing functionality. You enable routing on a specific VLAN by configuring a VLAN interface. See
the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide for more information about Layer 3
routing and VLAN interfaces.
By default, Layer 3 routing and multicasting come up automatically when you have an M-Series module
installed in the chassis with the N7K-F132-15 module. Layer 3 routing, multicasting, and load balancing
among the available M-Series works by default using proxy routing on the M-Series modules.
Optionally, you can specify which physical interfaces on the M-Series modules that you want to use for egress
multicast replication, as well as forcing rebalancing.
Before you begin
You must configure a VLAN interface for each VLAN on the N7K-F132-15 module where you want to use
the proxy-routing functionality in a mixed chassis.
You must have interfaces from both the M-Series and the N7K-F132-15 modules in the same VDC.
If you remove an interface from the VDC and then enter this command, the removed interface only display
when you reload the VDC.
License Requirement
Multicast replication requires no license.
However, PIM and PIM6 require an Enterprise
Services license. For a complete explanation of the
Cisco NX-OS licensing scheme and how to obtain
and apply licenses, see the Cisco NX-OS Licensing
Guide.
