Dynamic Routing Rules - D-Link NetDefendOS User Manual

Metric
4.6.3.5. OSPF Aggregates
OSPF Aggregation is used to combine groups of routes with common addresses into a single
entry in the routing table. If advertised this will decreases the size of the routing table in the
firewall, if not advertised this will hide the networks.
NetDefendOS OSPF Aggregate objects are created within an OSPF Area and each object has the
following parameters:
Network
Advertise
In most, simple OSPF scenarios, OSPF Aggregate objects will not be needed.
4.6.3.6. OSPF VLinks
All areas in an OSPF AS must be physically connected to the backbone area (the area with ID 0).
In some cases this is not possible and in that case a Virtual Link (VLink) can be used to connect to
the backbone through a non-backbone area.
NetDefendOS OSPF VLink objects are created within an OSPF Area and each object has the
following parameters:
General Parameters
Name
Neighbor Router ID
Authentication
Use Default For AS
In most, simple OSPF scenarios, OSPF VLink objects will not be needed.

4.6.4. Dynamic Routing Rules

This section examines Dynamic Routing Rules. These rules determine which routes can be
exported to an OSPF AS from the local routing tables and which can be imported into the local
routing tables from the AS.
4.6.4.1. Overview
The Final OSPF Setup Step is Creating Dynamic Routing Rules
Specifies the metric to this neighbor.
The network consisting of the smaller routers.
If the aggregation should be advertised or not.
Symbolic name of the virtual link.
The Router ID of the router on the other side of the virtual link.
Use the values configured in the AS properties page.
Note: Linking partitioned backbones
If the backbone area is partitioned, a virtual link is used to connect the different parts.
