OSPF Sumarization – Internal Router

 

OSPF Sumarization – Internal Router



 

ADA 2 CARA :

•Dikonfigurasi pada Router ABR (LSA Type 3)

 •Dikonfigurasi pada Router ASBR (LSA Type 5)

R1

R1(config)#do sh run | section ospf

R1(config)#router ospf 1

R1(config)# router-id 1.1.1.1

R1(config)# redistribute eigrp 10 subnets

R1(config)# network 1.1.1.1 0.0.0.0 area 0

R1(config)#network 12.12.12.1 0.0.0.0 area 0

R1(config)#network 100.100.100.1 0.0.0.0 area 100

R1(config)#network 100.100.100.2 0.0.0.0 area 100

R1(config)#network 100.100.100.3 0.0.0.0 area 100


Hapus terlebih dahulu untuk konfigurasi acl distribute list pada R2


R2

R2(config)#no access-list 1 permit 0.0.0.0 255.255.255.254

R2(config)#router ospf 2

R2(config-router)#no distribute-list 1 in

R2(config-router)#exit


Lalu cek routing tabel pada R3


R3

R3(config)#do sh ip route ospf

Konfigurasikan summarization di R1,.


R1

R1(config)#router ospf 1

R1(config-router)#area 100 range 100.100.100.0 255.255.255.248

R1(config-router)#exit


Cek lagi R3 dengan do sh ip route ospf


R3

R3(config)#do sh ip route ospf

yaa net 100.100.100.0 nya sudah di summary


Cek di R1.

di OSPF, discard route akan otomatis muncul bila summary route

dikonfigurasikan. itu gunanya untuk menghindari forwarding loop 

nah kita akan hapus sekarang , maka konfigurasi seperti berikut


R1

R1(config)#router ospf 1

R1(config-router)#no discard-route

R1(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...

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...
