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

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