Question

If Routing Information Protocol (RIP) version 1 or version 2 has already been configured on a FortiGate unit, which of the following statements is correct if the routes learned through RIP need to be advertised into Open Shortest Path First (OSPF)?

Options

  • AThe FortiGate unit will automatically announce all routes learned through RIP v1 or v2 to its
  • BThe FortiGate unit will automatically announce all routes learned only through RIP v2 to its OSPF
  • CAt a minimum, the network administrator needs to enable Redistribute RIP in the OSPF
  • DThe network administrator needs to configure a RIP to OSPF announce policy as part of the RIP
  • EAt a minimum, the network administrator needs to enable Redistribute Default in the OSPF

Why each option

To advertise routes learned through RIP into OSPF on a FortiGate unit, the network administrator must explicitly enable RIP route redistribution within the OSPF configuration.

AThe FortiGate unit will automatically announce all routes learned through RIP v1 or v2 to its

FortiGate units do not automatically announce routes learned via one dynamic routing protocol into another.

BThe FortiGate unit will automatically announce all routes learned only through RIP v2 to its OSPF

Route redistribution is not automatic and does not differentiate between RIP v1 and v2 for this general principle.

CAt a minimum, the network administrator needs to enable Redistribute RIP in the OSPFCorrect

Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) are distinct routing protocols, and routes learned by one protocol are not automatically shared with another; explicit redistribution of RIP routes must be enabled within the OSPF configuration to advertise them.

DThe network administrator needs to configure a RIP to OSPF announce policy as part of the RIP

While redistribution policies can refine the process, enabling 'Redistribute RIP' is the fundamental step, not a separate 'announce policy'.

EAt a minimum, the network administrator needs to enable Redistribute Default in the OSPF

Enabling 'Redistribute Default' would only advertise the default route into OSPF, not specific RIP-learned routes.

Concept tested: FortiGate Route Redistribution (RIP to OSPF)
