SWITCHING TECHNOLOGIES #20 :

HSRP ( TRACK ROUTE ) 

 

Untuk topology masih sama, Konfigurasikan di R2

R2
R2(config)#track 1 ip route 8.8.8.8/32 reachability
!
R2(config-track)#interface FastEthernet0/1
R2(config-if)#standby 1 track 1 decrement 20
Verifikasi
Pastikan R2 memiliki route 8.8.8.8/32
R2
R2#show ip route eigrp
8.0.0.0/32 is subnetted, 1 subnets

Fa0/1 1 110 P Active local 192.168.12.1 192.168.12.254

R2 statusnya adalah active dan prioritasnya adalah 110, kemudian
Shutdown interface loopback R3, dan perhatikan proses yang terjadi
berikutnya.

 
R3
R3(config)#interface lo0
R3(config-if)#shutdown
R3(config-if)#exit

Perhatikan statusnya akan berubah menjadi standby dengan nilai priority 90.
