VRRP TRACK ROUTE - SWITCHTECH #24

VRRP TRACK ROUTE - SWITCHTECH

Perhatikan topologi berikut ini,

Konfigurasi di R1

R1(config)#int f0/1

R1(config-if)#no sh

R1(config)#interface fastEthernet0/1

R1(config-if)#vrrp 1 track 1 decrement 20

R1(config-if)#track 1 ip route 8.8.8.8/32 reachability

Verifikasi dan Pastikan R1 memiliki route 8.8.8.8/32

R1(config)#do show ip route eigrp

23.0.0.0/24 is subnetted, 1 subnets

D 23.23.23.0 [90/30720] via 192.168.12.2, 00:01:02, FastEthernet0/1

8.0.0.0/32 is subnetted, 1 subnets

D 8.8.8.8 [90/156160] via 13.13.13.3, 00:00:04, FastEthernet0/0

Shutdown interface loopback R3, dan perhatikan proses yang terjadi berikutnya

R3(config)#int lo0

R3(config-if)#shutdown

R3(config-if)#exit

Perhatikan statusnya akan berubah dari Master menjadi Backup dengan nilai priority 90,

reachability Up->Down

R1(config)#

Fa0/1 1 90 3570 Y Backup 192.168.12.2 192.168.12.254

Dari sisi R1 akan berubah menjadi master dengan priority 100,

R1(config)#do show vrrp brief

Interface Grp Pri Time Own Pre State Master addr Group addr

Fa0/1 1 100 3570 Y Backup 192.168.12.2 192.168.12.254

Aktifkan kembali interface loopback R3

R3(config)#int lo0

R3(config-if)#no shutdown

R3(config-if)#exit
