Interconnection of Lots of Links Hello, english abbreviation is TRILL Hello) message carries out neighbour
Occupying the negotiation of relation, TRILL hello packet carries the transmitting terminal RB's of this TRILL hello packet
Neighbor list and the relevant information of this transmitting terminal RB.Wherein, the neighbor list of transmitting terminal RB records have
The information of all RB of neighborhood (neighbor state is Report) is there is with this transmitting terminal RB, one
The information of neighbours RB can record record by neighbours in neighbor list, and every neighbours record record
Content includes following 4 aspects: (English full name is Media in the medium access control of the port of neighbours RB
Access Control, english abbreviation is MAC) address, port-mark (English full name is Port Identity,
English abbreviation is Port ID) and system banner (English full name is System Identity, and english abbreviation is
System ID), these three attribute uniquely identifies a neighbours RB, and port-mark and system banner are also
Can be used to identify a RB；TRILL hello packet is held time；The priority of neighbours RB；Adjacent
(English full name is Virtual Local Area Nerwork, English to occupy RB desired appointment VLAN
It is abbreviated as VLAN), this VLAN is used for sending Layer 2 data message and IS-IS Link State bag (English
Literary composition full name is Link State Packet, and english abbreviation is LSP) protocol massages.Transmitting terminal RB's is relevant
Information includes the port mac address of transmitting terminal RB, Port ID and System ID etc..
