Abstract:
This document defines an enhancement to the Designated Forwarder (DF)
election process in Ethernet Virtual Private Network (EVPN)
environments. While traditional DF election operates at a per
Virtual Local Area Network (VLAN) or per group of VLANs (in case of
VLAN bundle or VLAN-aware bundle service) level, such granularity may
not be sufficient for applications requiring optimized or isolated
multicast forwarding. This specification introduces a refined DF
election mechanism that extends existing hash-based methods to
operate at a more granular level specifically at the tuple of
Ethernet Segment Identifier (ESI), VLAN, and multicast flow. This
approach enables improved traffic distribution, enhanced load
balancing, and greater deployment flexibility for multicast delivery
in EVPN based networks. The proposed method is designed to remain
compatible with existing DF election procedures while offering
targeted improvements for multicast scenarios.
