Setting OSPF Properties

Using the RiverMaster, you can define the following OSPF parameters:

HArea ID shared by the routers and the ANG.

HRouter ID that identifies the ANG to other devices in the OSPF area. The default value for this address is the IP address assigned to the Trusted interface on the ANG.

HAuthentication algorithm used to accept or reject routing table updates from other routers.

To route packets for remote clients using OSPF, the ANG also uses a set of fixed operating parameters. Table 4 lists these fixed OSPF parameters, which use common default values and cannot be changed.

Table 4 Fixed OSPF Parameters

Parameter	Meaning	Fixed Value
Preference	Determines how OSPF routes compete with	150
	routes from other protocols (such as RIP) in
	the ANG’s routing table. The route with the
	lowest preference value is selected.
Cost	Used when exporting a non-OSPF route from	1
	the ANG’s routing table into OSPF as an
	autonomous system (AS).
Type	Indicates which type of autonomous systems	Type 1 AS
	that routes exported from the ANG’s routing
	table become.
AS Export	Specifies how often autonomous system link	Once per second
Interval	advertisements are generated and exported.
