Nah disitukan ada null0 lagi seperti sebelum nya, untuk menghapusnnya

konfigurasi seperti ini :

R3

R3(config)#router ospf 3

R3(config-router)#no discard-route

R3(config-router)#exit


Cek kembali DI R3


R3

R3(config)#do sh ip ro

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...

EIGRP – Filtering – Distribute List

  EIGRP – Filtering – Distribute List Cara pertama : filter network menggunakan access list pada R1 dengan distribute IN. Pada lab ini, kita masih menggunakan lab sebelumnya.  R1  R1(config)#access-list 1 deny 2.2.2.2  R1(config)#access-list 1 permit any  R1(config)#router eigrp 10  R1(config-router)#distribute-list 1 in gigabitEthernet 1/0  R1(config-router)#exit  Kemudian cek pada routing tabelnya. Pastikan IP 2.2.2.2 sudah tidak lagi terdapat dalam routing tabelnya.  R1  R1#sh ip route  1.0.0.0/32 is subnetted, 1 subnets  C 1.1.1.1 is directly connected, Loopback0   3.0.0.0/32 is subnetted, 1 subnets  D 3.3.3.3 [90/156416] via 12.12.12.2, 01:18:53, GigabitEthernet1/0   23.0.0.0/24 is subnetted, 1 subnets  D 23.23.23.0 [90/28416] via 12.12.12.2, 01:23:38, GigabitEthernet1/0   12.0.0.0/24 is subnetted, 1 subnets  C 12.12.12.0 is directly connected, GigabitEthernet1/0  Cara kedu...
