Message forwarding method and device, equipment and medium

The invention relates to a message forwarding method and device, equipment and a medium, and the method comprises the steps: when a fault node exists on a first message forwarding path of a message, and the fault node is one of all routing nodes with the same routing information in a multi-source network, the fault node is selected from the routing nodes with the same routing information as the fault node, and the fault node is selected from the routing nodes with the same routing information as the fault node; determining an alternative node; on a first adjacent node of the fault node, a timer of which the timing duration is a preset duration is set, the first adjacent node is a previous hop routing node of the fault node in the first message forwarding path, and the preset duration is greater than the duration required by all routing nodes in the multi-source network to complete convergence; before the timer is overtime, identifying the replacement node as a destination node for forwarding the message; and
