• Now recommended to use route authentication for OSPF

  • …and all other routing protocols

• Susceptible to denial of service attacks

  • OSPF runs on TCP/IP
  • Automatic neighbour discovery

• Route authentication – Cisco example:

  router ospf <pid>
  
  network 192.0.2.0 0.0.0.255 area 0
  area 0 authentication
  interface ethernet 0/0
  ip ospf authentication-key <password>
