The router is a computer two or more Inter face network (NICCARD) in it which serves to connect two or more networks so that he biased eneruskan packets from one network to another.
Default Gateway of a network is a router that is used to forwardsbuah Router that is used to forward paket2x of such networks toother networks.
Usually configure the LAN at LAN belongs only to find her and Default Gateway. If in a LAN there is no DEFAULT GATEWAYthe LAN it is not biased connected with other networks.
So in order to perform routing then setting / network configurationis needed to add one more that is DEFAULT GATEWAY
.
TABEL ROUTINGIn order to serve the demand router to forward bias the data transmission then the router must have Tabelyang in use asbenchmark data should I send to the network where ??????
Tables are on a call by the router in the Routing Table that contains the netid and its DEFAULT GATEWAY.
From the picture above is the scenario of sending data fromcomputer to computer 198.168.2.36 192.168.1.5.
1. Computer 192.168.1.5 wants to send data to the destinationaddress of 192.168.2.36 to realize that not on the local networkcomputer search list on the DEFAULT GATEWAY PROPERTYTEP / IP is 192.168.1.13 then send data packets to theGATEWAY.
2. On the computer 192.168.1.13 packet back in check andfound on the Routing table that the package can be sent to the network via IP 192.168.2.43 192.168.2
3. Via 192.168.2.43 end IP data can be transmitted to thedestination of 192.168.2.36
