OSPF version 2 is a routing protocol which is described in RFC 2328. OSPF is for IPv4 only. OSPF is an IGP. Compared with RIP, OSPF can provide scalable network support and faster convergence times. OSPF is widely used in large networks such as ISP backbone and enterprise networks.
You can find the OSPF Settings at Routing → OSPF.
You can set a Router ID that is advertised or let the system configure one automaticlly.
Main Area the main Area of this OSPF instance.
Redistribute Kernel Routes lets OSPF automatically distribute Kernel Routes.
Redistribute Static Routes lets OSPF automatically distribute Static Routes.
Redistribute Connected Routes lets OSPF automatically distribute Connected Routes.
Please be aware that VT AIR static routes are classified as kernel routes.
Default Route Route Map lets you filter the default route with a Route Map.
Networks let you specify which interface will be advertised if it is in that network. Please be aware that OSPF only advertises networks that the host system has an IP address in. You can not advertise random networks.
16.6.1. OSPF Interface¶
Each OSPF Interface that you want to advertise needs to be defined under Routing → OSPF → OSPF Interface.
Interface sets the interface and can only be used once.
Network Type will be detected automatically but you can override it here.
Interface Area must be set to the correct area of the interface.
Metric for this interface if you want to override it.
Passive turns the interface into a stub network.
Priority for the DR selection.
MD5 if you need to enable authentication.
