• Static routing is a way of making the routing table manually. This is useful for sederhanayang network using only a few routers and also to save bandwidth usage.

Excess static routing

• There is no bandwidth is used between the routers.
• no overhead on the router.
  
• Add security, because the admin can choose to fill the routing access kejaringan

lack of static routing

• Admin should really understand the internetwork, how each can configure the router connected to the router.
• If there is a new network, the network admin have to route to any router manually

Static Routing

IP routing is always applied (enable) for Cisco routers, so to make a static IP routing simply by typing the command:
Router(config)#ip route <network destination id> <subnet mask> <next hoop/default gateway>

Routing Information Protokol (RIP)

Routing protocol is the simplest of the type of distance vector. RIP uses the hop (hop count) as a metric with a maximum of 15 hops, so if the hop count to 16 then the router will give the message "destinatination is unreachable" (goal not met), RIP protocol routing table updated every 30 seconds.

• invalid timer merupakan waktu dalam detik, router dinyatakan tidak berfungsi
  
• holddown timer
  
• flush timer

Interior Gateway Routing Protokol(IGRP)

Types include IGRP distance vector is created to deal with problems on the RIP protocol, the maximum number of hops to 255. IGRP is a routing protocol included in the autonomous system (AS), the default administrative distance for IGRP is 100.

Note:

Autonomous system is a set of routers that use the same protocol RIP dimisalkan in a management protocol.

Dinamic Routing

• Distance vector : how far, the router to find the shortest path to reach the destination network
• Link State : how fast,who has the ideology that is not necessarily the shortest, this fast in the shortest possible path, there is traffic congestion, and link state to see the amount of available bandwidth, routers usually link state has specifications above average aka expensive.

As an administrative network is of course we must know the network topology by the routing table to see the only form of letters and numbers only, of course this is a problem that exists for a junior admin, will teach here sonny see topology of the routing table, consider the well<br /> Router1#show ip route<br /> Codes: C - connected, S - Static, I - IGRP, R - RIP, M - Mobile, B - BGP, D - EIGRP, EX -EIGRP external, O - OSPF, IA - OSPF area, E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP, I -IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * -candidate default Gateway of last resort is not set<br /> C 192.168.110.0 is directly connected, Eternet 0<br /> C 192.168.10. is directly connected, Serial0<br /> R 192.168.20.0 [120/1] via 192.168.10.11, 00:00:30, Serial0<br /> R 192.168.30.0 [120/1] via 192.168.10.11, 00:00:30, Ethernet0

Every time the Cisco router is turned on, this equipment will perform a routine process that is called the boot process, the boot process is working through a specific sequence as follows:

• First the router will run the Power On Self Test (POST) to check the CPU, memory and interface equipment to ensure that the router hardware to function properly.
• Then bootstrap the system will work for a Cisco IOS image that can be used. Generally this Cisco IOS image can be obtained from flash memory or from the tftp server, depending on the configuration list is used by the equipment. By default this configuration register value 0x2102 which will tell the router to find the IOS image from flash memory.
• IOS image search efforts conducted 5 times, if not successful, the router will enter ROM mode to enable the IOS image manually.
• If the IOS image found, the IOS image will be loaded into RAM memory system
• Then, the router will look for first configuration (start-up configuration) which is generally found in NVRAM
• If the router is turned on for the first time, the router has yet to have a first configuration, and the router will run the system configuration dialog that allows the creation of first configuration manually.

The device is owned by the router has to similarities with the computer device comprising:

• ROM allows you to save a bootstrap system that serves to regulate the boot process and run the Power on Self Test (POST) and the IOS image
• NVRAM configuration store that served the initial (start-up configuration)
• RAM which has the task to save the running configuration (running configuration) and Cisco IOS operating systems are active.
• FLASH useful to store the IOS image, using FLASH, a new version of IOS can be obtained from the TFTP server without having to replace components in the router.
