EIGRP merupakan distance vector protocol dan cisco proprietary. Menggunakan algoritma DUAL (Diffusing Update Algorithm).

  • Advanced distance vector/hybrid routing protocol
  • Multicast or unicast for exchange information use port 88
  • Administrative distance 90
  • Classless routing protocol support VLSM/CIDR.
  • Support IPv6
  • Rich metric (bandwidth, delay, load and reliability)
  • Very fast convergence
  • Equal and Unequal Load balancing
  • 100% loop-free

Dinamakan advanced distance vector atau hybrid routing protocol karena EIGRP tidak seperti RIP yang:

  • No neighbor discovery
  • Periodic updates
  • Vulnerable to loops
  • Simple metric (hop count)

Cisco menambahkan fitur-fitur dari link state pada EIGRP sehingga dapat mengatasi masalah-masalah RIP. Pada router yang menjalankan EIGRP akan mempunyai 3 database(tabel):

EIGRP neighbor table

  • List semua directly connected neighbor
  • Next-hop router
  • Interface

EIGRP topology table

  • List semua route yang dipelajari dari semua EIGRP neighbor
  • Destination
  • Metric

Routing table

  • Best route dari EIGRP topology table

Successor and Feasible Successor

  • Successor = best path to destination
  • Feasible Successor = backup link to destination

EIGRP Packets

Hello Packet

  • Untuk discover dan recovery neighbor serta membentuk adjency.
  • Jika penerima membalas dengan hello packet maka terjadi adjency. Jika penerima tidak mengirim hello packet dalam X waktu (hold time), maka adjency akan didrop.
  • Setelah adjency terbentuk, akan melakukan exchange routing information yang akan disimpan di topology table. Best path dari topology table akan disave di routing table.
  • Reliable

Update Packet

  • Berisi informasi routing
  • Dapat dikirim secara unicast atau multicast
  • Reliable

Query Packet

  • Dikirim jika suatu router EIGRP kehilangan informasi tentang suatu network, maka query akan dikirim ke neighbor untuk mendapat informasi tentang neighbor yang hilang tadi.

Reply Packet

  • Response dari query packet

ACK Packet

  • Dikirim sebagai pemberitahuan bahwa telah menerima update packet.
  • Dikirim secara unicast.

No Auto-Summary
Digunakan untuk menyertakan subnetmask dalam advertise network.

Konfigurasi EIGRP. Advertise network ke dalam routing EIGRP. Autonomous Number (AS Number) harus sama pada setiap router.

EIGRP FIltering - Distribute List
#

Diguanakn untuk memfilter network berdasarkan route network yang masuk dan keluar interface. Pada topologi dibawah, tujuannya agar ip loopback 2.2.2.2 tidak ada dalam routing tabel R1.

Cara pertama: filter network menggunakan access list pada R1 dengan distribute IN.

eigrp

Masih menggunakan lab sebelumnya.

access-list 10 deny 2.2.2.2
access-list 10 permit any
router eigrp 10
distribute-list 10 in Serial0/0

Cek ip route.

R1#sh ip route

Gateway of last resort is not set

    1.0.0.0/32 is subnetted, 1 subnets
C       1.1.1.1 is directly connected, Loopback0
    3.0.0.0/32 is subnetted, 1 subnets
D       3.3.3.3 [90/2809856] via 12.12.12.2, 00:00:39, Serial0/0
    23.0.0.0/24 is subnetted, 1 subnets
D       23.23.23.0 [90/2681856] via 12.12.12.2, 00:00:39, Serial0/0
    12.0.0.0/24 is subnetted, 1 subnets
C       12.12.12.0 is directly connected, Serial0/0
R1#

Cara kedua: filter network menggunakan access list pada R2 dengan distribute OUT. Pastikan ip loopback 2.2.2.2 ada lagi dalam tabel routing R1 lalu pada R2 ketik perintah dibawah.

router eigrp 10
access-list 10 deny 2.2.2.2
access-list 10 permit any
distribute-list 10 out Serial0/0

Cek routing tabel pastikan ip loopback 2.2.2.2 tidak ada.

EIGRP FIltering - Prefix List
#

Memfilter network berdasarkan prefix. Ketika dimasukkan prefix list IN pada R2, maka network R3 yang dideny oleh R2 tidak akan diadvertise ke R1.

eigrp

Masih menggunakan lab sebelumnya. Tujuannya agar network pada R3 dengan prefix 24 sampai 28 diblok, selain itu ditampilkan.

R1
interface Loopback0
ip address 1.1.1.1 255.255.255.255

interface Serial0/1
ip address 23.23.23.2 255.255.255.0
!
router eigrp 10
network 0.0.0.0

R3
interface Loopback0
ip address 3.3.3.3 255.255.255.255
!
interface Serial0/0
ip address 23.23.23.3 255.255.255.0
!
router eigrp 10
network 0.0.0.0
no auto-summary
!

Pada R1, buat ip loopback yang bervariatif untuk difilter.

interface Loopback1
 ip address 3.3.3.17 255.255.255.240
!
interface Loopback2
 ip address 3.3.3.33 255.255.255.248
!
interface Loopback3
 ip address 3.3.3.150 255.255.255.252
!
interface Loopback4
 ip address 3.3.3.200 255.255.255.240
!
interface Loopback5
 ip address 3.3.3.100 255.255.255.224
!

Cek tabel routing R1.

EIGRP Unicast Update

Secara default EIGRP melakukan update melalui ip multicast 224.0.0.10, unicast update mengganti update dari multicast ke unicast neighbornya.

Cek bahwa EIGRP mengirim update secara multicast. IP multicast adalah 244.0.0.10

Untuk mengaktifkan load balancing, harus dicari nilai variencenya. Varience adalah 2739200 : 435200 = 6.29412, berapapun komanya bulatkan kebawah sehingga menjadi 7.

Dengan nilai varience 7, artinya setiap 7 packet dikirimkan melalui link pertama dan 1 packet melalui link kedua.

Sekarang set nilai variencenya.

R1(config-if)#router eigrp 16

Cek apakah sudah load balancing.

IPv6

·24 menit· loading
Cisco Packet Tracer Cisco Networking IPv6
Pengguna internet berkembang sangat pesat sehingga space IPv4 yang tersedia juga semakin sedikit. Apalagi dengan banyaknya perangkat seperti telepon dan tablet yang butuh koneksi internet juga turut mengurangi space IPv4. Solusinya adalah dengan IPv6 yang mempunyai space ip yang jauh lebih banyak.
