Licensing Requirements for Static Routing
Remote Next Hops for Static Routes
You can specify the next-hop address of a neighboring router which is not directly connected to the
router for static routes with remote (non-directly attached) next-hops. If a static route has remote
next-hops during data-forwarding, the next-hops are recursively used in the unicast routing table to
identify the corresponding directly attached next-hop(s) that have reachability to the remote next-hops.
Virtualization Support
Static routes support Virtual Routing and Forwarding instances (VRFs). VRFs exist within virtual device
contexts (VDCs). By default, Cisco NX-OS places you in the default VDC and default VRF unless you
specifically configure another VDC and VRF. For more information, see the Cisco Nexus 7000 Series
NX-OS Virtual Device Context Configuration Guide, Release 4.x and see Chapter 14, “Configuring
Layer 3 Virtualization.”
Licensing Requirements for Static Routing
The following table shows the licensing requirements for this feature:
Prerequisites for Static Routing
Static routing has the following prerequisites:
• If the next-hop address for a static route is unreachable, the static route will not be added to the
unicast routing table.
Guidelines and Limitations
Static routing has the following guidelines and limitations:
• You can specify an interface as the next-hop address for a static route only for point-to-point
interfaces such as GRE tunnels.
Configuring Static Routing
This section includes the following topics:
• Configuring a Static Route, page 13-4
• Configuring Virtualization, page 13-5
Product License Requirement
NX-OS Static routing 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 NX-OS
licensing scheme, see the Cisco NX-OS Licensing Guide
