Configure LAN State Propagation

Let us learn to configure the LAN state propagation.
LAN state propagation allows propagating a LAN port's link state to its corresponding WAN port in a bypass pair. When LAN connectivity to a downstream switch is lost, the LAN port state is communicated to the upstream WAN device, thereby allowing traffic to take alternate paths through other

LAN ports. LAN State Propagation is applicable only in the LAN-to-WAN direction. In effect, when a LAN port in a bypass pair goes down, it also brings down the corresponding WAN port of the bypass pair. However, in a failure with a WAN port, the LAN port will continue to remain up.

    Thus, when a LAN port in a bypass pair goes down, it also brings down the corresponding WAN port of the bypass pair.
