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.

1. A method for changing an appointed forwarding device, comprising:
receiving, by a first routing bridge, an appointment packet for appointing the first routing bridge as an appointed forwarding device of a virtual local area network, wherein the appointment packet is broadcast by a designated routing bridge; entering, by the first routing bridge, a forwarding state after receiving the appointment packet; and forwarding, by the first routing bridge, a packet of the virtual local area network after determining that the first routing bridge is in a state of being inhibited from forwarding packets of the virtual local area network and after receiving a first advertisement packet carrying an identifier of the virtual local area network sent by a second routing bridge, wherein the first advertisement packet is a broadcast packet and is 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 virtual local area network, wherein the second routing bridge is an original appointed forwarding device of the virtual local area network, and wherein the state of being inhibited from forwarding the packets of the virtual local area network occurs when an inhibition timer associated with the first routing bridge is not expired.
