abr-type {cisco |
ibm | shortcut |
standard}
Specify the behavior of a FortiGate unit
acting as an OSPF area border router
(ABR) when it has multiple attached areas
and has no backbone connection.
Selecting the ABR type compatible with
the routers on your network can reduce or
eliminate the need for configuring and
maintaining virtual links. For more
information, see RFC 3509.

database-overflow
{disable | enable}
Enable or disable dynamically limiting link
state database size under overflow
conditions. Enable this command for
FortiGate units on a network with routers
that because of limited resources may not
be able to maintain a complete link state
database.
disable All models.
database-overflow-
max-lsas
<lsas_integer>
If you have enabled database-
overflow, set the limit for the number of
external link state advertisements (LSAs)
that the FortiGate unit can keep in its link
state database before entering the
overflow state. The lsas_integer must
be the same on all routers attached to the
OSPF area and the OSPF backbone. The
valid range for lsas_integer is 0 to
4294967294.
10000 All models.
database-overflow-
time-to-recover
<seconds_integer>
Enter the time, in seconds, after which the
FortiGate unit will attempt to leave the
overflow state. If seconds_integer is
set to 0, the FortiGate unit will not leave
the overflow state until restarted. The valid
range for seconds_integer is 0 to
65535.

<metric_integer>
Specify the metric for the default route set

information-route-
map <name_str>
If you have set default-information-
originate to always, and there is no
default route in the routing table, you can

parameters that OSPF uses to advertise
the default route.
