Belajar Konfigurasi Basic HSRP (Hot Standby Router Protocol)
Topology yang digunakan adalah sebagai berikut:

nb:
-Shadow cnc Pada kenyataannya tidak ada.
-cnc1 merupakan router primary dengan priority 100
-cnc2 merupakan router secondary dengan priority 50

Konfigurasinya adalah sebagai berikut :

Router cnc 1 :
interface FastEthernet0/0
 ip address 192.168.10.3 255.255.255.0
 standby 10 ip 192.168.10.1
 standby 10 priority 100
 standby 10 preempt
!kalau tidak diberi perintah preempt, jika ingin kembali normal,router harus
!di reboot terlebih dahulu.
 standby 10 track FastEthernet1/0 60
!perintah ini mengantisipasi, jika f1/0 down secara otomatis priority agar berkurang
!sebesar 60 (100-60=40) hal ini menyebabkan cnc2 berubah dari state stanby -> active

!jika konfigurasi benar akan muncul line seperti berikut:
*Mar 28 12:30:52.291: %HSRP-5-STATECHANGE: FastEthernet0/0 Grp 10 state Standby -> Active

Router cnc 2 :
interface FastEthernet0/0
 ip address 192.168.10.2 255.255.255.0
 standby 10 ip 192.168.10.1
 standby 10 priority 50
 standby 10 preempt

!jika konfigurasi benar akan muncul line seperti berikut:
*Mar 28 12:31:12.843: %HSRP-5-STATECHANGE: FastEthernet0/0 Grp 10 state Speak -> Standby
