Hi David, If you want to combine L2 and L3 forwarding on a VXLAN interface, use a BVI as Petr suggests. If you want the VXLAN tunnels to only act like an L3 interface, then you can use create the tunnels in L3 mode.

What I want is to have a packet flow that: 1. performs vxlan decap -> routing on the overlay packet -> vxlan encap, such as in the case of overlay routing between 2 VNIs. 2. allows configuring overlay routes in VPP that points to VXLAN tunnels. Is this supported natively in VPP? If so, is there an example configuration sequence I can use as a reference? Thanks, David
