Virtualization Support

You must configure a VLAN interface for each VLAN on the N7K-F132-15 module that you want to use the
proxy-routing functionality in a chassis that contains both N7K-F132-15 and M-Series modules. See the Cisco
Nexus 7000 Series Interfaces Configuration Guide for information on configuring VLAN interfaces.
By default, all of the physical interfaces on the M-Series modules in the VDC become proxy routing ports
for the VLANs that are configured with VLAN interfaces on the Layer 2-only N7K-F132-15 module in the
same VDC. The physical interfaces on the M-Series module can be administratively down and they still pass
traffic as proxy routers.
Packets that enter an interface on the N7K-F132-15 module are automatically forwarded to one of the interfaces
on the M-Series modules in the same VDC to be routed. The interface on the M-Series module also performs
egress replication for Layer 3 multicast packets that enter an interface on the N7K-F132-15 module in the
same VDC. See the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration Guide for additional
information about the routing interoperation with the N7K-F132-15 module.
You can specify which interfaces on the M-Series modules in the VDC where you want to perform the egress
replication of VLAN interfaces for Layer 3 multicast packets. For multicast egress replication, the system
automatically rebalances all the VLAN interfaces among all the available M-Series proxy routing interfaces.
You can specify automatic or manual rebalancing among the proxy multicast replicators. If you specify manual
rebalancing, you trigger a rebalance by entering a command. This command is useful when you are inserting
or removing modules.
Note When you configure manual egress multicast replication load balancing and enter the rebalancing command,
that command is not part of the configuration. It is not included in the commands that are copied when you
enter the copy running-config startup-config command.
Virtualization Support
You must have interfaces from both the M-Series and the N7K-F132-15 modules in the same VDC.
See the Cisco Nexus 7000 Series Virtual Device Context Configuration Guide for more information about
VDCs.

High Availability
