Method and Apparatus for Changing Appointed Forwarding Device

摘要

A method and an apparatus for changing an appointed forwarding device. A first routing bridge receives an appointment packet for appointing the first routing bridge as an appointed forwarding device of a virtual local area network (VLAN); and immediately enters a forwarding state and starts to forward a packet of the VLAN, if the first routing bridge is in a state of being inhibited from forwarding packets of the VLAN when the first routing bridge receives a first advertisement packet carrying an identifier of the VLAN sent by a second routing bridge; the first advertisement packet is a broadcast packet and used to notify a neighboring routing bridge that the second routing bridge sending the first advertisement packet is not the appointed forwarding device of the VLAN; and the second routing bridge is an original appointed forwarding device of the VLAN application.
