II-1-9 OSPF
OSPF(Open Shortest Path First), running within the AS, is a routing protocol based on IP protocol. It
uses the algorithm of SPF (Shortest Path First) to calculate the route metric. It is suitable for large
network and complicated data exchange. Vigor router supports up to OSPF version 2(for IPv4) and
OSPF version 3(for IPv6).
The Autonomous System (AS) used in OSPF can be divided into several areas. Usually, Area 0 will be
used as OSPF backbone which distributing the routing information among areas.
When you need faster convergence than distance vector, want to support much larger networks or
want to have less susceptible to bad routing information, you can enable OSPF feature to fit your
request. Note that both routers must support OSPF function at the same time to build the OSPF
connection.
II-1-9-1 General Setup
This page allows you to configure general settings for OSPFv2 (IPv4) and/or OSPFv3 (Ipv6) profile.
Available settings are explained as follows:
Item
Enabled
Router ID
Connected
Static
RIP
Description
General Setup
Switch the toggle to enable/disable the OSPFv2 function.
Specify the IPv4 address of the Vigor router for routing and neighbor
discovery.
Such ID will help Vigor router to be identified in an autonomous
system. However, if no address is specified, then an IP address of the
active interface will be used by system automatically.
All Networks – Apply the OSPF profile to all the LAN interfaces.
Exclude NAT Networks - Apply the OSPF profile to all the LAN
interfaces except for NAT network.
Switch the toggle to apply the static route to the OSPF profile.
Switch the toggle to enable (allow dynamically route traffic based on
information learned from the RIP protocol) or disable the function.
