Chapter 9 Configuring RIP
Licensing Requirements for RIP
Cisco NX-OS supports the Equal Cost Multiple Paths (ECMP) feature with up to 16 equal-cost paths in
the RIP route table and the unicast RIB. You can configure RIP to load balance traffic across some or all
of those paths.
Virtualization Support
Cisco NX-OS supports multiple instances of the RIP protocol that runs on the same system. RIP supports
Virtual Routing and Forwarding instances (VRFs).
By default, Cisco NX-OS places you in the default VRF unless you specifically configure another VRF.
See Chapter 11, “Configuring Layer 3 Virtualization.”

The following table shows the licensing requirements for this feature:

and drops the packet.

Default Settings
Table 9-1 lists the default settings for RIP parameters.
Product License Requirement
Cisco NX-OS RIP requires no license. Any feature not included in a license package is bundled with the Cisco NX-OS
system images and is provided at no extra charge to you. For a complete explanation of the Cisco NX-OS
licensing scheme, see the Cisco NX-OS Licensing Guide.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
