Three-tier switch is crossed to be communicated.The network segment where website A and B belongs to the directly connected subnet on interchanger, if website A and website B
Not in same subnet, dispatching station A first has to send ARP request message to its " default gateway ", and the IP of " default gateway "
Location is exactly the IP address of the affiliated VLAN of website A on three-tier switch in fact.When dispatching station A is broadcasted the IP address of " default gateway "
When going out an ARP request, interchanger just returns an ARP to dispatching station A and replys message, tells this VLAN of website A interchangers MAC
Address, while the information such as website A IP address, MAC Address, the port numbers that are joined directly together with interchanger can be set by software
Put in three layers of hardware table item of exchange chip.After website A receives this ARP reply messages, carry out target MAC (Media Access Control) address and replace
Change, B to be issued bag is issued interchanger first.After interchanger receives this bag, source MAC is equally carried out first
Practise, target MAC (Media Access Control) address is searched, in this case will be this because now target MAC (Media Access Control) address is the MAC Address of interchanger
Message is sent to three layers of engine processing of exchange chip.In general, three layers of engine have two tables, and one is Host routes table,
This table is the information such as the inside storage purpose IP address, next-hop mac address, port numbers using IP address as index.If find
One matching list item, will afterwards will carrying out certain operations (such as purpose MAC and source MAC is replaced, TTL subtracts 1) to message
The port that message is specified from table forwards.If not finding matching entry in Host routes table, may proceed to search another
Individual table-- network segment routing table.The information such as this table storage network segment address, next-hop mac address, port numbers.In general this
The entry of table wants much less, but the scope covered is very big, as long as setting is proper, can substantially ensure that major part enters interchanger
Message all walk hardware forwarding, so not only greatly improve forwarding speed, while also mitigate CPU load.If search the network segment
Routing table does not find matching list item yet, then exchange chip can give bag CPU processing, carry out soft route, is also referred to as
CPU., can be directly using B IP as rope after CPU receives this IP message because website B belongs to one of directly connected subnet of interchanger
Draw inspection arp cache, if without website B MAC Address, stood according to routing iinformation to B and broadcast an ARP request, B stations obtain
Its MAC Address is replied to interchanger after this ARP request, CPU again may be by while this ARP reply messages are received
Software sets three layers of hardware to exchange chip website B IP address, MAC Address, into information such as the port numbers of interchanger
In list item, the IP messages sent by website A are then transmitted to website B, the first time this completes website A to website B
One-way communication.Due to saved website A, B routing iinformation in three layers of engine of chip internal, enter between later website A, B
The website of row communication or other network segments is wanted to be communicated with A, B, and exchange chip then can be directly bag from three layers of hardware table item
The port specified forwards, without giving CPU processing bag again.This mode by " once routeing, repeatedly exchange ",
Substantially increase forwarding speed.It should be noted that the route table items in three layers of engine are mostly by software design patterns.
