Abstract:
Ethernet Virtual Private Network (EVPN) is commonly used with Network
Virtualization Overlay (NVO) tunnels, as well as MPLS and Segment
Routing tunnels. The multi-homing procedures in EVPN may vary based
on the type of tunnel used within the EVPN Broadcast Domain.
Specifically, there are two multi-homing Split Horizon procedures
designed to prevent looped frames on multi-homed Customer Edge (CE)
devices: the ESI Label-based procedure and the Local Bias procedure.
The ESI Label-based Split Horizon is applied to MPLS-based tunnels,
such as MPLSoUDP, while the Local Bias procedure is used for other
tunnels, such as VXLAN.
Current specifications do not allow operators to choose which Split
Horizon procedure to use for tunnel encapsulations that support both
methods. Examples of tunnels that may support both procedures
include MPLSoGRE, MPLSoUDP, GENEVE, and SRv6. This document updates
the EVPN multi-homing procedures described in RFC 8365 and RFC 7432,
enabling operators to select the Split Horizon procedure that meets
their specific requirements.
