I denne opgave kan du enten vælge at konfigurere OSPF eller BGP alt efter preference. Eller hvert medlem af holdet kan konfigurere hver sin protokol:-)

OSPF
Tegning findes i klassen.
Default timers:
- Hello
- 10 sekunder
- Dead
- 40 Sekunder
Implmentering
For at konfigurere OSPF på en SRX kasse skal man igennem følgende skridt:
- Konfigurer router-id
- Konfigurer OSPF interfaces
- Herunder passiv interfaces
- Sæt reference båndbredde
- Tillad OSPF i host-inbound
- Kontroller det virker
Router-ID
Konfiguration af Router-ID finder sted under router-options stanza.
Router-ID er et 32 bits streng skrevet i dotted decimal notation som en IPv4 adresse.
Router-ID kan ikke være i 0.0.0.0/8 eller 127.0.0.0/8 området.

<notice>router-id 24.24.24.24;</notice>Reference båndbredde
Default reference båndbredde ligger på 100Mbit/s, så den alle links på 100Mbit/s og over vil have en cost på 1.
Her ændrer vi den til 10Gbit/s istedet.
