Usage Guidelines

The vPC peer-gateway functionality allows a vPC switch to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This feature enables local forwarding of such packets without the need to cross the vPC peer-link. In this scenario, the feature optimizes use of the peer-link and avoids potential traffic loss.

You must configure the peer-gateway functionality on both vPC peer switches.

Note This command is applicable to a Cisco Nexus 5548 switch and Cisco Nexus 5596 switch.

This command does not require a license.

Examples

This example shows how to enable the vPC peer gateway:
