Time Settings
SPF Hold Time
Specifies the minimum time, in seconds, between two SPF calculations.
The default time is 10 seconds. A value of 0 means that there is no delay.
Note however that SPF can potentially be a CPU demanding process, so
in a big network it might not be a good idea to run it to often.
SPF Delay Time
Specifies the delay time, in seconds, between when OSPF receives a
topology change and when it starts a SPF calculation. The default time is
5 seconds. A value of 0 means that there is no delay. Note however that
SPF can potentially be a CPU demanding process, so in a big network it
might not be a good idea to run it to often.
LSA Group Pacing
This specifies the time in seconds at which interval the OSPF LSAs are
collected into a group and refreshed. It is more optimal to group many
LSAs and process them at the same time, instead of running them one and
one.
Routes Hold Time
This specifies the time in seconds that the routing table will be kept
unchanged after a reconfiguration of OSPF entries or a HA failover.
Memory Settings
Memory Max Usage
Maximum amount in Kilobytes of RAM that the OSPF AS process are
allowed to use, if no value is specified the default is 1% of installed
RAM. Specifying 0 indicates that the OSPF AS process is allowed to use
all available ram in the firewall.
4.5.3.2. OSPF Area
The Autonomous System (AS) is divided into smaller parts called an Area, this section explains
how to configure areas. An area collects together OSPF interfaces, neighbors, aggregates and virtual
links.
An OSPF area is a child of the OSPF router process and there can be many area objects defined
under a single router process. In most simple networking scenarios, a single area is sufficient. Like
the router process object, a similar area object should be defined on all the NetDefend Firewalls
which will be part of the OSPF network.
General Parameters
Name
Specifies the name of the OSPF Area.
ID
Specifies the area id. If 0.0.0.0 is specified then this is the
backbone area.
There can only be one backbone area and it forms the central
portion of an AS. Routing information that is exchanged between
different area always transits the backbone area.
Is stub area
Enable this option if the area is a stub area.
Become Default Router
It is possible to configure if the firewall should become the default
router for the stub area, and with what metric.
