Abstract

The present invention provides a method for forwarding messages in a TRILL network and a routing bridge. The method includes: the first routing bridge finds that no entry including the destination MAC address is stored in the MAC address table, and cannot unicast forward the first data. message, it will actively send the MAC address request message with the destination MAC address of the first data message as the target MAC address, and quickly obtain the second routing bridge corresponding to the destination MAC address of the first data message information, so that the first routing bridge can use the TRILL unicast method to send the subsequent received second data message including the destination MAC address according to the information of the second routing bridge, effectively reducing the traffic in the TRILL network. TRILL multicast traffic saves the multicast bandwidth of the TRILL network and increases bandwidth utilization.

Description

technical field [0001] The invention relates to communication network technology, in particular to a method for forwarding messages in a TRILL network and a routing bridge. Background technique [0002] Transparent Interconnection of Lots of Links (English: Transparent Interconnection of Lots of Links, referred to as: TRILL) is a two-layer network standard recommended by the Internet Engineering Task Force (English: Internet Engineering Task Force, referred to as: IEIF). Among them, the device running the TRILL protocol is called Routing Bridge (English: Route Bridge, RB for short), a network composed of RBs is called a TRILL network. [0003] Forwarding in the TRILL network is essentially Layer 2 forwarding, and it is necessary to search a Media Access Control (English: Media Access Control Address, MAC for short) address table. When the ingress routing bridge (English: Ingress RB) receives the message, if it can find out the MAC address corresponding to the egress routing...
