Cisco router (Basic)

Komponen-komponen internal router:

1
1. RAM/Dynamic RAM, fungsinya:
- Menjaga ARP cache
- Menjaga fast switching cache
- Melakukanpenjagaanpaket
- Memeliharaantrianpaket

2. NVRAM, fungsinya: (NVRAM=BIOS (di computer))
- Menyediakanpenyimpanan u/ startup configuration file
- Mempertahankanisi file konfigurasiketika router dimatikan/restart

3. FLASH Memory, fungsinya: (FLASH =Harddisk(di computer))
- Memberikan software u/ diperbaharuitanpamengganti chips processor
- Jenisygsecaraelektrikdapatdihapus

4. ROM, fungsinya:
- Menyimpan program bootstrap &dasar software SO
- Membutuhkanpenggantian chip pada motherboard u/ meningkatkanmutu software

5. Interface,fungsinya:
- Menghubungkan router kejaringanuntuk frame ygmasuk/keluar
- Interface dapatditambah

 

Cisco IOS Software, fungsinya:
1. Fungsidasar routing & switching
2. Realibility&pengamananakseskesumberjaringan
3. Network scalability

Static Routing & Dynamic Routing
Routing: proses penentuanarahygterjadipada router ygdigunakanuntukmeneruskanpaket data kejaringantujuan.

Contoh protocol routing:
1. routing information protocol (RIP)
2. Interior Gateway Routing Protocol (IGRP)
3. Enhanced Interior Gateway Routing Protocol (EIGRP)
4. Open Shortest Path First (OSPF)
