Local Bias

Local bias involves replicating multi-destination traffic received from the access side to all directly attached Ethernet Segments (ESs), regardless of the Designated Forwarder (DF) election state.

This behavior differs from the default split-horizon (SH) rule and is specifically applicable to Border Gateway Protocol (BGP) Ethernet Virtual Private Network (EVPN) with Virtual Extensible LAN (VXLAN) tunnel encapsulation.
