hay guys kali ini saya akan membagikan sedikit tentang HSPR, dan ini salah satu materi yg saya pelajari saat saya training cisco
Pengertian: HSRP (Hot Standby Redundancy Protocol) salah satu protokol FHRP (First Hop Redundancy Protocol). HSRP adalah bawaan cisco dan hanya bisa berjalan apa bila router di network juga menggunakan router cisco. jadi HSRP adalah cisco proprietary.pada HSRP paket hello menggunakan UDP port 1985 dengan ip 224.0.0.2 pada HSRP versi 1 dan ip 224.0.0.102 pada HSRP versi 2 (IOS 12.2 (46)SE keatas sudah pakai versi 2.
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 ------------------------------------------------------------- cnc1(config-if)#standby ? <0-255> group number authentication Authentication bfd Enable HSRP BFD delay HSRP initialisation delay follow Name of HSRP group to follow ip Enable HSRP IPv4 and set the virtual IP address ipv6 Enable HSRP IPv6 mac-address Virtual MAC address mac-refresh Refresh MAC cache on switch by periodically sending packet from virtual mac address name Redundancy name string preempt Overthrow lower priority Active routers priority Priority level redirect Configure sending of ICMP Redirect messages with an HSRP virtual IP address as the gateway IP address timers Hello and hold timers track Priority tracking use-bia HSRP uses interface's burned in address version HSRP version cnc1(config-if)#standby cnc1(config-if)#standby 10 ? authentication Authentication follow Name of HSRP group to follow ip Enable HSRP IPv4 and set the virtual IP address ipv6 Enable HSRP IPv6 mac-address Virtual MAC address name Redundancy name string preempt Overthrow lower priority Active routers priority Priority level timers Hello and hold timers track Priority tracking cnc1(config-if)#standby 10 cnc1(config-if)#standby 10 ip? ip ipv6 cnc1(config-if)#standby 10 ip ?
