Description

Default

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.

cisco

All models.

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.

disable All models.

default-
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

the default route.
