Konfigurasi EIGRP

  1.    TOPOLOGI

  2.    KONSEP DASAR
EIGRP disebut juga sebagai routing protocol distance vector, terkadang disebut juga advanced
distance vector atau routing protocol hybrid.
Berikut ini beberapa fitur dari EIGRP :
· Cisco open standar protocol (sebelumnya proprietary)
· Termasuk classless routing protocol
· Update perubahan topologi secara dinamis
· Metric (32 bit) : Composite Metric (BW + Delay + Load + MTU + Reliability)
· Administrative Distance: 90
· Update menggunakan multicast: 224.0.0.10
· Jumlah maksimum hop count: 255 (default 100)
· Mendukung protocol IP, IPX, Apple Talk
· Hello packet dikirim setiap 5 second (dead interval 15 second)
· Konvergensi cepat
· Menggunakan algoritma DUAL (Diffusing Update Algorithm)
· Mendukung equal dan unequal cost load balancing
EIGRP memaintain tiga tabel
1. Neighbor table
- Menampilkan informasi directly connected router
- Command: show ip eigrp neighbor
2. Topology table
- Menampilkan semua best route yang dipelajari dari masing-masing neighbor
- Command: show ip eigrp topology
3. Routing table
- Menampilkan best route menuju network destination
- Command: show ip route
Notes EIGRP
· EIGRP menggunakan autonomous system number (ASN) untuk mengidentifikasi routerrouter yang sharing informasi route
· Hanya router yang memiliki ASN sama yang bisa sharing informasi route
Dua step menggunakan routing protocol dinamis secara umum:
1. Pilih routing protocol
2. Advertise directly connected network (jaringan yang terhubung langsung dengan router)
Keuntungan EIGRP
· Terdapat backup route jika best route down (successor=primary, feasible
successor=backup)
· Mendukung VLSM

3.    PEMBERIAN IP

a.    Router0

Router>enable

Router#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#hostname R0

R0(config)#interface fastEthernet 0/0

R0(config-if)#ip address 10.10.10.1 255.255.255.0

R0(config-if)#no shutdown

R0(config-if)#exit

R0(config)#interface fastEthernet 0/1

R0(config-if)#ip address 192.168.10.1 255.255.255.0

R0(config-if)#no shutdown

b.    Router1

Router>enable

Router#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#hostname R1

R1(config)#interface FastEthernet 0/0

R1(config-if)#ip address 10.10.10.2 255.255.255.0

R1(config-if)#no shutdown

R1(config-if)#exit

R1(config)#interface Ethernet0/1/0

R1(config-if)#ip address 192.168.20.1 255.255.255.0

R1(config-if)#ip address 20.20.20.1 255.255.255.0

R1(config-if)#no shutdown

c.    Router2

Router>enable

Router#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#hostname R2

R2(config)#interface FastEthernet0/0

R2(config-if)#ip address 20.20.20.2 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#exit

R2(config)#interface FastEthernet0/1

R2(config-if)#ip address 192.168.30.1 255.255.255.0

R2(config-if)#no shutdown

R0(config-router)#no auto-summary

R0(config-router)#do wr

Building configuration...

[OK]

b.    Setting R1

R1(config)#router eigrp 100

R1(config-router)#network 10.10.10.0

R1(config-router)#network 20.20.20.0

R1(config-router)#network 192.168.20.0

R1(config-router)#no auto-summary

R1(config-router)#do wr
