OSPF Configuration on the Interface
STEP TWO
Contrary to most other protocols in CyROS, OSPF must first be configured on each interface, then configured in
the CONFIG =>IP =>OSPF menu.  Enter into each interface and set the parameters listed in the table.
OSPF Menu CONFIG =>INTERFACE =>
<LINK> =>ROUTING PROTOCOL =>OSPF
Parameter
Description
OSPF on This
Interface
Activates OSPF.  Enable Inactive is used to temporarily disable the OSPF protocol
without erasing the parameters set below.  This is useful when OSPF is first configured,
as the general parameters must be set afterwards in CONFIG=>IP =>OSPF and OSPF
cannot function without them.
Parameters that apply only when OSPF on This Interface is Disabled.
Advertise This Non-
OSPF Interface
Causes the router to include this interface in its advertisements through other interfaces
(as an external route).
External Metric
Defines the metric that will be advertised by OSPF.
External Metric Type For Type 1, the total metric of this route is composed of the internal metric (inside the
autonomous system) and the external metric (provided in the previous parameter).  For
Type 2, the total metric of this route is the value provided in the previous parameter.
Parameters that apply only when OSPF on This Interface is Enable or Enable Inactive.
Area ID
Identifies the area to which the interface belongs.  Areas are created here, then later
defined in CONFIG=>IP=>OSPF =>AREA.   Has the format of an IP address, but is not
linked to any IP address in the system.  Small OSPF networks will typically have only
one area (the backbone area represented by 0.0.0.0).
Router Priority
Priority used by OSPF in multicast networks to elect the designated router. A priority of
1 will make this router the most likely to be chosen.  A priority of 2 will make it second
most likely.  Set it to 0 (zero) if this router should never be the designated router.
Transit Delay in
Seconds
Estimated transit time in seconds to route a packet through this interface.  Use the
preset value (1) or increase the number for slow links
