Switching Lab 20 : HSRP – Track Route

 LAB 20

Untuk topologi 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 
D 8.8.8.8 [90/158720] via 192.168.12.1, 00:06:05, FastEthernet0/1 
 13.0.0.0/24 is subnetted, 1 subnets 
D 13.13.13.0 [90/30720] via 192.168.12.1, 00:00:44, FastEthernet0/1 

R2(config)#do show standby brief 

 P indicates configured to preempt. 
 | Interface Grp Pri P State Active Standby Virtual IP 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.

R2

R2(config)#

1 90 P Standby 192.168.12.1 local 192.168.12.254 

Dari sisi R1 akan berubah menjadi active dengan priority 100

Aktifkan kembali interface loopback R3

R3

R3(config)#int lo0 
R3(config-if)#no shutdown 
R3(config-if)#exit
