Selecting Advanced Ospf Options - Fortinet Fortigate-5000 series Administration Manual

OSPF

Selecting advanced OSPF options

198
Advanced OSPF options let you specify metrics for redistributing routes that the
FortiGate unit learns through some means other than OSPF link-state
advertisements. For example, if the FortiGate unit is connected to a RIP or BGP
network or you add a static route to the FortiGate routing table manually, you can
configure the FortiGate unit to advertise those routes on OSPF-enabled
interfaces.
To select advanced RIP options, go to Router > Dynamic > RIP and expand
Advanced Options. After you select the options, select Apply.
Figure 109:Advanced Options (OSPF)
Default Generate and advertise a default (external) route to the OSPF AS. The
generated route may be based on routes learned through a dynamic
Information
routing protocol, or routes in the routing table, or both.
None Disable the generation of a default route.
Regular Generate a default route into the OSPF AS and advertise the
route to neighboring autonomous systems only if the route is
stored in the FortiGate routing table.
Always Generate a default route into the OSPF AS and advertise the
route to neighboring autonomous systems unconditionally,
even if the route is not stored in the FortiGate routing table.
Redistribute Enable or disable OSPF link-state advertisements about routes that were
not learned through OSPF. The FortiGate unit can use OSPF to
redistribute routes learned from directly connected networks, static routes,
RIP, and/or BGP.
Connected Select to redistribute routes learned from directly connected
networks.
If you want to specify a cost for those routes, enter the cost in
the Metric field. The range is from 1 to 16 777 214.
Static Select to redistribute routes learned from static routes.
If you want to specify a cost for those routes, enter the cost in
the Metric field. The range is from 1 to 16 777 214.
RIP Select to redistribute routes learned through RIP.
If you want to specify a cost for those routes, enter the cost in
the Metric field. The range is from 1 to 16 777 214.
BGP Select to redistribute routes learned through BGP.
If you want to specify a cost for those routes, enter the cost in
the Metric field. The range is from 1 to 16 777 214.
Note: Many additional advanced OSPF options can be configured through the CLI. For
details, see the "router" chapter of the FortiGate CLI Reference.
