METHOD AND SYSTEM FOR STATIC TRILL ROUTING

摘要

A method and system for static routing in a TRILL network is disclosed. Routing bridges in the TRILL network use LLDP discovery to identify their next hop routing bridges. A data packet, with an inner header specifying a MAC address of a destination host, is sent by a source host and received by an ingress routing bridge. The ingress routing bridge encapsulates the data packet with a TRILL header and an outer header and sends the data packet to a next hop routing bridge on path to the destination host. The next hop routing bridge determines it is not the egress routing bridge for the data packet and sends the data packet onward to the egress routing bridge. The egress routing bridge decapsulates the data packet and forwards the data packet to the destination host specified in the inner header.
