Konfigurasi Interface

Router1:

vtysh
configure terminal
  ! ipv6 forwarding
  interface eth1
    ip address 10.10.1.1/30
    ipv6 address 2001:10:10:1::1/64
    ipv6 ospf6 network broadcast
    ipv6 ospf6 instance-id 1
    no shutdown
    exit
  ! ipv6 forwarding
  interface eth2
    ip address 10.10.1.5/30
    ipv6 address 2001:10:10:5::1/64

    no shutdown
    ip route 0.0.0.0/0 192.168.122.1
  end

Router2:

Konfigurasi OSPF

Ada tiga (3) elemen dasar konfigurasi OSPF:

  • Enable OSPF instance
  • OSPF area configuration
  • OSPF network configuration

Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.

R1

vtysh
configure terminal
  router-id 10.10.1.1
  router ospf
    network 10.10.1.0/30 area 0.0.0.0
    network 10.10.1.4/30 area 0.0.0.0
    exit
  router ospf6
    log-adjacency-changes 
    router-id 10.10.1.1
    interface eth1 area 0.0.0.0
    interface eth2 area 0.0.0.0 
    interface eth3 area 0.0.0.0 
    area 0.0.0.0 range 2001:10:10:1::/64
    area 0.0.0.0 range 2001:10:10:5::/64
    redistribute connected 
    redistribute kernel    
    redistribute static 
  end

R2

vtysh
configure terminal
  router-id 10.10.1.5
  router ospf
    network 10.10.1.4/30 area 0.0.0.0
    network 10.10.1.8/30 area 0.0.0.0
    network 172.16.0.0/16 area 0.0.0.0
    exit
  router ospf6
    log-adjacency-changes 
    router-id 10.10.1.5
    interface eth1 area 0.0.0.0 
    interface eth2 area 0.0.0.0
    interface eth3 area 0.0.0.0  
    area 0.0.0.0 range 2001:10:10:5::/64
    area 0.0.0.0 range 2001:10:10:9::/64
    area 0.0.0.0 range 2001:172:16:1::/64
    redistribute connected 
    redistribute kernel    
    redistribute static 
  end

R3

vtysh
configure terminal
  router-id 10.10.1.2
  router ospf
    network 10.10.1.0/30 area 0.0.0.0
    network 10.10.1.8/30 area 0.0.0.0
    network 192.168.1.0/24 area 0.0.0.0
    exit
  router ospf6
    log-adjacency-changes 
    router-id 10.10.1.2
    interface eth1 area 0.0.0.0 
    interface eth2 area 0.0.0.0 
    interface eth3 area 0.0.0.0 
    area 0.0.0.0 range 2001:10:10:1::/64
    area 0.0.0.0 range 2001:10:10:9::/64
    area 0.0.0.0 range 2001:192:168:1::/64
    redistribute connected 
    redistribute kernel    
    redistribute static 
  end
