The following table shows the licensing requirements for this feature:
Guidelines and Limitations
VRRP has the following configuration guidelines and limitations:
• You cannot configure VRRP on the management interface.
• When VRRP is enabled, you should replicate the VRRP configuration across switches in your
network.
• We recommend that you do not configure more than one first-hop redundancy protocol on the same
interface.
• You must configure an IP address for the interface that you configure VRRP on and enable that
interface before VRRP becomes active.
• Cisco NX-OS removes all Layer 3 configuration on an interface when you change the interface VRF
membership, port channel membership, or when you change the port mode to Layer 2.
• When you configure VRRP to track a Layer 2 interface, you must shut down the Layer 2 interface
and reenable the interface to update the VRRP priority to reflect the state of the Layer 2 interface.
Default Settings
Table 15-1 lists the default settings for VRRP parameters.
Product License Requirement
Cisco NX-OS VRRP 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.
