CCNP - High Avaibalitiy HSRP (Hot Standby Router Protocol)
Lab 58 HSRP Hot Standby Router Protocol
High avaibalitiy ini terbagi menjadi 3 :
- HSRP (Hot Standby Redundancy Protocol): yaitu salah satu protocol FHRP
(First Hop Redundancy Protocol). HSRP merupakan salah satu cisco propitary
- VRRP (Virtual Router Reality protocol): VRRP ini merupkan salah satu
protocol high avaibality yang mana ia sudah open untuk hampir beberapa
vendor, konsep nya tidak jauh berebeda dengan HSRP, yaitu menyediakan
backup gateway, sehingga apabila gateway utama mati maka akan pindah ke
gateway backup
- GLBP (Gateway Load Balancing Protocool): GLBP melindungi traffik data
dari kegagalan yang terjadi di router, seperti HSRP, Perbedaan GLBP dan HSRP
adalah bahwa GLBP menyediakan load-balancing, yaitu mendistribusikan
beban trafik pada dua atau lebih jalur koneksi secara seimbang
Kita kasih IP dan konfigurasi HSRP-nya
R1(config)#interface FastEthernet0/0
R1(config-if)#ip address 13.13.13.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#interface FastEthernet0/1
R1(config-if)#no shutdown
R1(config-if)#ip address 192.168.12.1 255.255.255.0
R1(config-if)#standby 1 ip 192.168.12.254
R1(config-if)#standby 1 preempt
R1(config-if)#standby 1 authentication md5 key-string cisco
R1(config-if)#router eigrp 1
R1(config-router)#net 0.0.0.0
R1(config-router)#no auto-summary
R2(config)#interface FastEthernet0/0
R2(config-if)#ip address 23.23.23.2
255.255.255.0 R2(config-if)#no shutdown
R2(config-if)#interface FastEthernet0/1
R2(config-if)#ip address 192.168.12.2 255.255.255.0

R2(config-if)#router eigrp 1

R3(config-if)#no shutdown
R3(config-if)#interface f0/1
R3(config-if)#ip address 23.23.23.3 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#interface Loopback 0
R3(config-if)#ip address 8.8.8.8 255.255.255.255
R3(config-if)#router eigrp 1
R3(config-router)#net 0.0.0.0
R3(config-router)#no auto-summary
Setting IP juga di PC
PC1> ip 192.168.12.10/24 192.168.12.254
PC2> ip 192.168.12.11/24 192.168.12.254
Kita cek HSRP-nya
R1#show standby brief
P indicates configured to preempt.
Interface Grp Pri P State Active Standby Virtual IP Fa0/1 1
100 P Standby192.168
.12.2 local 192.168.12.254
R2(config-if)#do sh 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
Kita coba matikan interface fa0/1
R2(config)#int f0/1
R2(config-if)#shutdown
R2(config-if)#exit
Kita cek lagi di PC-2
PC2> ping 8.8.8.8
84 bytes from 8.8.8.8 icmp_seq=2 ttl=254 time=13.678 ms
84 bytes from 8.8.8.8 icmp_seq=3 ttl=254 time=12.628 ms 8.8.8.8
icmp_seq=1 timeout
8.8.8.8 icmp_seq=22 timeout
84 bytes from 8.8.8.8 icmp_seq=7 ttl=254 time=30.278 ms
84 bytes from 8.8.8.8 icmp_seq=8 ttl=254 time=23.097 ms 84 bytes from
8.8.8.8 icmp_seq=9 ttl=254 time=23.630 ms
Berhasil deh.... :)
