BGP Authentication

Untuk keamanan, BGP menerapkan authentication untuk establishing neighbor sehingga neighbor yang dimaksud saja yang bisa peering.

Hapus BGP 1234 kemudian lakukan langkah dibawah.

R1(config)#router bgp 1234 R1(config-router)#neighbor 2.2.2.2 password 5 CCIE123 R1(config-router)#neighbor 3.3.3.3 password 5 CCIE123 R1(config-router)#neighbor 4.4.4.4 password 5 CCIE123 R2(config)#router bgp 1234 R2(config-router)#neighbor 1.1.1.1 password 5 CCIE123 R2(config-router)#neighbor 3.3.3.3 password 5 CCIE123 R2(config-router)#neighbor 4.4.4.4 password 5 CCIE123 R3(config)#router bgp 1234 R3(config-router)#neighbor 1.1.1.1 password 5 CCIE123 R3(config-router)#neighbor 2.2.2.2 password 5 CCIE123 R3(config-router)#neighbor 4.4.4.4 password 5 CCIE123 R4(config)#router bgp 1234 R4(config-router)#neighbor 1.1.1.1 password 5 CCIE123 R4(config-router)#neighbor 2.2.2.2 password 5 CCIE123 R4(config-router)#neighbor 3.3.3.3 password 5 CCIE123
