LVTEP is a Logical VTEP (Virtual
Tunnel End Point) distributed across an MCT pair (Multi-Chassis Tunnel pair) with both
devices configured with same VTEP IP. By default, the Local Bias
is disabled for
LVTEP BUM (Broadcast, Unicast, and Multicast) traffic handling.
Follow this procedure to configure Local Bias.
efa fabric setting update -–name <fabric-name> --overlay-gateway-broadcast-local-bias {Yes|No}
lvtep-broadcast-local-bias
configuration enables Local
Bias to handle LVTEP BUM traffic. Note
overlay-gateway-broadcast-local-bias
fabric
setting on a fabric before the fabric is configured.The lvtep-broadcast-local-bias
fabric settings apply
on switches even though the fabric configured the feature with the
supported SLX Platforms (SLX-9540, SLX-9640, SLX-9150, SLX-9250,
SLX-9740, SLX-8520, SLX-8720, SLX-882, and SLX Firmware Version
20.4.3 and above).
If there is any drift in Global Configuration, the efa fabric show command displays that the ”SYSP-C/U” configuration is pending.
lvtep-broadcast-local-bias
configuration is
applicable only for the dual-homed leaf or border-leaf devices and is
not applicable for the single-homed leaf or border-leaf devices.lvtep-broadcast-local-bias
configuration is applicable for
both Clos and non-Clos fabrics.lvtep-broadcast-local-bias
fabric setting can be enabled
only when the backup-routing-enable
fabric setting is enabled.For syntax and command examples, see the ExtremeCloud Orchestrator Command Reference, 3.2.0 .
