EIGRP - Stub (Connected Summary)

Pada lab ini, kita akan belajar EIGRP Stub Connected + Summary

Arti dari stub adalah ujung,artinya  router yang menjalankan EIGRP
berada di paling akhir dan tidak terhbung dengan protocol routing lain

Arti dari Connected adalah Internal EIGRP atau Router lokal yang menjalankan
EIGRP, misal IP Loopback yang di advertise ke EIGRP merupakan Connected karena
ia di pasang langsung di router lokal.

Arti dari Summary yaitu rangkuman, di lab ini yang disummary atau yang di
ringkas yaitu IP Loopback 1 -4 R2


langsung aja konfigurasi yah

Konfigurasi IP Address  dan EIGRP di R1

interface Loopback0
 ip address 1.1.1.1 255.255.255.255
!
interface Serial2/0
 ip address 12.12.12.1 255.255.255.0
 serial restart-delay 0
!

router eigrp 10
 network 12.12.12.0 0.0.0.255



Konfigurasi IP Address  dan EIGRP di R2

interface Loopback0
 ip address 2.2.2.2 255.255.255.255
!

Konfigurasi IP Address dan EIGRP di R3

interface Loopback0
 ip address 3.3.3.3 255.255.255.255

Konfigurasi Summary pada  R2 di Interface yang mengarah ke R3

interface Ethernet0/0
 ip address 23.23.23.1 255.255.255.0
 ip summary-address eigrp 10 22.22.22.0 255.255.255.192



Konfigurasi EIGRP Stub di R2

Pada routing table di atas, artinya R2 sukses memberikan info update routing
EIGRP ke R3 bahwa network 22.0.0.0/26 merupakan summary dari ip loopback R2.

EIGRP STUB RECEIVE ONLY


EIGRP Receive only artinya R2 ini tidak akan memberikan update Informasi
routing EIGRP ke R3, sehingga R3 tidak akan menampilkan network di R2.
