Setting OSPF Properties
Using the RiverMaster, you can define the following OSPF parameters:
H Area ID shared by the routers and the ANG.
H Router 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.
H Authentication 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.
