disable ospf export [bgp | direct | e-bgp | i-bgp | rip | static]
These commands enable or disable the exporting of RIP, static, and direct routes by way of
LSA to other OSPF routers as AS-external type 1 or type 2 routes. The default setting is
disabled.
LSA to other OSPF routers as AS-external type 1 or type 2 routes. The default setting is
disabled.
The cost metric is inserted for all Border Gateway Protocol (BGP), RIP, static, and direct
routes injected into OSPF. If the cost metric is set to 0, the cost is inserted from the route. For
example, in the case of BGP export, the cost equals the multiple exit discriminator (MED) or
the path length. The tag value is used only by special routing applications. Use 0 if you do not
have specific requirements for using a tag. (The tag value in this instance has no relationship
with IEEE 802.1Q VLAN tagging.)

The same cost, type, and tag values can be inserted for all the export routes, or policies can
be used for selective insertion. When a policy is associated with the export command, the
policy is applied on every exported route. The exported routes can also be filtered using
policies.

Note:
For routes exported to OSPF via a policy file, any refresh applied on
that policy may result in temporary withdrawal and then immediate
readvertising of those routes.

Verify the configuration using the command:

OSPF Timers and Authentication
Configuring OSPF timers and authentication on a per area basis is a shortcut to applying the
timers and authentication to each VLAN in the area at the time of configuration. If you add
more VLANs to the area, you must configure the timers and authentication for the new
VLANs explicitly. Use the command:
timers and authentication to each VLAN in the area at the time of configuration. If you add
more VLANs to the area, you must configure the timers and authentication for the new
VLANs explicitly. Use the command:
configure ospf vlan [<vlan-name> | all] timer <retransmit-interval>
<transit-delay> <hello-interval> <dead-interval> {<wait-timer-interval>}
Configuring OSPF
Each switch that is configured to run OSPF must have a unique router ID. NETGEAR
recommends that you manually set the router ID of the switches participating in OSPF,
instead of having the switch automatically choose its router ID based on the highest interface
IP address. Not performing this configuration in larger, dynamic environments could result in
an older LSDB remaining in use.
