3. configuratie

 

  • begin met een fysieke constructie in packettracer
  • geef hostnames aan R1 en R3
  • vergeet de ipv6 unicast-routing niet
  • geef adressen aan de twee PC's, vergeet de default gateway niet ...
  • geef adressen aan deze router interfaces: R1-gi0/1 | R3-gi0/1 | R1-gi0/0 | R3-gi0/0
  • je hoeft in principe geen link-local adressen te declareren op de Gi0/0 noch op de Gi0/1; de routers cre-eren normaal gezien zelf link-local adressen. 
    R1> show ipv6 interface brief
    GigabitEthernet0/0         [up/up]
  FE80::20C:CFFF:FE7C:1801
  3FFF:1234:ABCD:BEEF::1
GigabitEthernet0/1         [up/up]
  FE80::20C:CFFF:FE7C:1802
  2B01:1234:5678:9ABC::11
  • vergeet de OSPF declaraties niet in de router interfaces ... 
    interface GigabitEthernet0/1
ipv6 address 2B01:1234:5678:9ABC::11/64
ipv6 ospf 1 area 0
  • kun je pingen tussen PC1 en PC3
  • kijk ook even in simulatiemode, zie je NDP paketten of router solicitations ?
  • geef een router-id 1.1.1.1 aan R1, en een router-id 3.3.3.3 aan R3
  • controlleer de werking van OSPF met show ipv6 route en show ipv6 ospf
  • voeg de Lo0 interfaces toe op R1 en R3; vind je die na een korte tijd terug in de show ipv6 route?
  • kan je pingen van een PC naar een Lo0 op de andere router?
     

4. ping ...

 

C:\> ping 2b03:1234:5678:9abc::c3
 
Pinging 2b03:1234:5678:9abc::c3 with 32 bytes of data:
Reply from 2B03:1234:5678:9ABC::C3: bytes=32 time<1ms TTL=126

 

5. show ipv6 route

 

R3> sh ipv6 route

6. show ipv6 ospf neighbor

 

R3> sh ipv6 ospf neighbor
