Abstract
A method for managing a MAC address entry in a TRILL network is disclosed. A first routing bridge obtains a TCN message through a switch connected to the first routing bridge. The first routing bridge clears a MAC address entry of the first routing bridge taking the first routing bridge as an egress bridge and sends a LSP packet to a second routing bridge in the TRILL network, so as to enable the second routing bridge to clear a MAC address entry of the second routing bridge taking the first routing bridge as the egress bridge. The second routing bridge and the first routing bridge are located in the same VLAN.
Claims8
A method for managing a media access control (MAC) address entry in a Transparent Interconnection of Lots of Links (TRILL) network, the method comprising:
- obtaining, by a first routing bridge, a topology change notification (TCN) packet through a switch connected to the first routing bridge;
- clearing, by the first routing bridge, a MAC address entry of the first routing bridge taking the first routing bridge as an egress bridge, the Mac entry being cleared according to the TCN message;
- and
- sending, by the first routing bridge, a link state protocol data unit (LSP) packet to a second routing bridge in the TRILL network.
A method for managing a media access control (MAC) address entry in a Transparent Interconnection of Lots of Links (TRILL) network, the method comprising:
- receiving, by a second routing bridge, a link state protocol data unit (LSP) packet sent by a first routing bridge, wherein the first routing bridge and the second routing bridge are located in the same virtual local area network (VLAN);
- and
- clearing, by the second routing bridge, a MAC address entry of the second routing bridge taking the first routing bridge as an egress bridge.
A routing bridge, comprising:
- an obtaining unit, configured to obtain a topology change notification (TCN) packet through a switch connected to the routing bridge;
- a clearing unit, configured to clear, according to the TCN message, a media access control (MAC) address entry of the routing bridge taking the routing bridge as an egress bridge;
- and
- a sending unit, configured to send a link state protocol data unit (LSP) packet to a second routing bridge in a Transparent Interconnection of Lots of Links (TRILL) network.
A routing bridge, comprising:
- a receiving unit, configured to receive a link state protocol data unit (LSP) packet sent by a first routing bridge, wherein the first routing bridge and the routing bridge are located in the same virtual local area network (VLAN);
- and
- a clearing unit, configured to clear a media access control (MAC) address entry of the routing bridge taking the first routing bridge as an egress bridge.
