Lab 15. OSPF - Summarization Summary Address

konfigurasi routing untuk di set summary ;

R1(config)#router ospf 1
R1(config-router)#no network 10.10.10.0 0.0.0.255 area 1
R1(config)#router eigrp 1
R1(config-router)#network 10.10.10.0 0.0.0.7
R1(config-router)#no auto-summary
R1(config)#router ospf 1
R1(config-router)#redistribute eigrp 1 subnets

cek table routing di R3

Konfigurasikan External route summary di R1

R1(config)#router ospf 1
R1(config-router)#summary-address 10.10.10.0 255.255.255.248

cek kembali routing table R3 dan R1

Untuk menghapus Null0 konfigurasikan perintah dibawah ini kemudian cek kembali table routingnya dan pastikan Null0 hilang

R1(config)#router ospf 1
R1(config-router)#no discard-route external
