This example shows how to bind a vPC to the default VRF instance using VLAN 2:
switch(config)# vpc bind-vrf default vlan vlan2

Enabling Layer 3 Forwarding to the Gateway MAC Address of the vPC

The vPC peer-gateway feature allows a vPC switch to act as the active gateway for packets that are addressed
to the router MAC address of the vPC peer. You can enable local forwarding 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 can enable Layer 3 forwarding for packets destined to the gateway MAC address of the virtual Port
Channel (vPC).
Note You must configure this feature on both vPC peer switches.
