L3VNI

A VXLAN VNI associated with a tenant VRF, used to carry routed traffic between VTEPs in symmetric IRB.

Definition

The L3VNI is bound to a VRF and a dedicated transit VLAN with an SVI on Cisco NX-OS. Routes in that VRF are advertised as Type 2 and Type 5 routes carrying the L3VNI and router MAC.

Example

vlan 3001 / vn-segment 50001 ; interface Vlan3001 / vrf member TENANT-A / ip forward

Exam tip

The L3VNI must match on all VTEPs for that VRF.
