OSPF External Route Tipe-1

 

OSPF External Route Tipe-1




 

• Redistribute pada OSPF ada 2 macam, yaitu redistribute metric type 1 dan redistribute metric type

• Perbedaan keduanya terletak pada cost yang akna diberikan kepada setiap network hasil redistribute tersebut

HAPUS CONFIG LAB SEBELUMNYA , KARENA INI LAB LANJUTAN

110 menunjukkan administrator distance OSPF, sedangkan

20 menunjukkan metric yang digunakan oleh R2 menuju network tersebut.

Metricnya sama baik ketika route tersebut di R1 ataupun R2. Selanjutnya ubah

agar menjadi External Type 1 



R3(config)#router ospf 3

R3(config-router)#redistribute rip subnets metric-type ?

 1 Set OSPF External Type 1 metrics

 2 Set OSPF External Type 2 metrics

R3(config-router)#redistribute rip subnets metric-type 1

R3(config-router)#exit


R3(config)#router ospf 3

R3(config-router)#redistribute rip subnets route-map TIPE-SATU

R3(config-router)#exit

Phase 1 Dynamic Mapping With EIGRP

  Phase 1 Dynamic  Mapping With EIGRP Tentu kalian sudah tau, apa yang akan kita bahas pada blogg ini yaitu    Phase 1 Dynamic Mapping With EIGRP . ..  Nah Pada lab Sekarang buat routing eigrp pada setiap router baik hub  atau spoke untuk menghubungkan jaringan local masing-masing spoke  atau hub, dalam hal ini ip loopback akan kita anggap sebagai ip jaringan  local kita gaessss. Dan disini seperti di judul, kita menggunakan routing EIGRP lagi yaa... Oiya, karena ini adalah lab lanjutan dari lab VPN sebelumnya... soo saya hanya melakukan konfigurasi yang hanya pada lab ini saja, dan jika temen - temen ingin melihat konfigurasi dasarnya dari lab ini... temen - temen bisa lihat di lab - lab sebelumnya... silahkan copy dan paste link dibawah ini.. 👉https://insinyurbocah2109.blogspot.com/2020/11/belajar-vpn-gre-tunnel.html BELAJAR VPN ( GRE TUNNEL ) - Lab 1 VPN 👉 https://insinyurbocah2109.blogspot.com/2020/11/belajar-vpn-ipsec-tunnel-mode.html BELAJ...

Konfigurasi Event OSPF Adjacency (Email)

  Konfigurasi Event OSPF Adjacency (Email) LAB INI LANJUTAN SAMA SEPERTI LAB SEBELUM SEBELUMNYA Selain event syslog tadi kita juga bisa memanfaatkan EEM ini untuk mengirimkan informasi ke email kita, misalnya OSPF kita down maka, router kita otomatis akan mengirimkan debug ospf ke email kita. Untuk topology masih sama. KONFIG R1 R1(config)#event manager applet OSPF_DOWN R1(config-applet)#event syslog pattern "Nbr 2.2.2.2 on FastEthernet0/0 from FULL to DOWN" R1(config-applet)#action 1.0 cli command "enable" R1(config-applet)#action 2.0 cli command "debug ip ospf adj" R1(config-applet)#action 3.0 mail server "smtp.gmail.com" to "uuqeili@gmail.com" from "R1@idn.id" subject "OSPF IS DOWN" body "Please fix OSPF" R1(config-applet)#exit Untuk Pengecekkan, kita bisa coba debug aja,  dan hapus EEM interface down,  Dan kita bisa lihat di email kita apa hasilnyaa... selesai
