Load Balancing

You can use load balancing to allow a router to distribute traffic over all the router network ports that are
the same distance from the destination address. Load balancing increases the utilization of network
segments and increases effective network bandwidth.
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.

High Availability

Cisco NX-OS supports stateless restarts for RIP. After a reboot or supervisor switchover, Cisco NX-OS
applies the running configuration and RIP immediately sends request packets to repopulate its routing
table.

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). VRFs exist within virtual device contexts (VDCs).
You can configure up to four RIP instances on a VDC. By default, Cisco NX-OS places you in the default
VDC and default VRF unless you specifically configure another VDC and VRF. See the Cisco NX-OS
Virtual Device Context Configuration Guide and
