Abstract:
E-VPN can be used as a control plane protocol for NVO3 network. In All-Active
access scenario, loop & echo forwarding prevention among multi-homed NVEs relies
on "Split horizon" filtering mechanism. ESI MPLS label is leveraged to perform
split horizon filtering in MPLS based EVPN network. In VXLAN or NVGRE
encapsulation based overlay network, no MPLS is used. Therefore a new method is
introduced in this document to achieve split horizon filtering in non-MPLS overlay
network. Data plane of the overlay network is extended with a LAGID field. The
function of LAGID is similar to ESI MPLS Label in [EVPN]. It is used to identify
each Ethernet segment(ES) on each NVE.
