- Summaries —Configure whether area border routers advertise summary routes into an NSSA.
When enabled, this floods summary LSAs into the NSSA.
-
No-Summaries —Configure whether area border routers advertise summary routes into an NSSA.
When checked, this prevents area border routers from advertising summaries into an NSSA. If
default-metric is configured for an NSSA, a Type 3 LSA is injected into the area by default.

Interface
This portion of the screen lets you select an OSPF interface (or delete one).
Figure 13-103. Routing Instances -> VRF Instances - OSPF and OSPF3 (Interface)
You must select an existing area to add/edit/delete interfaces for a given area with this portion of
the screen. When you
Add or Edit, the following fields appear:
-
Name —Name of the interface. To configure all interfaces, you can specify all . Enable OSPF
routing on a router interface. You must include at least one interface statement in the
configuration to enable OSPF on the router.
-
Hello Interval —Specify how often the router sends hello packets out the interface. The hello
interval must be the same for all routers on a shared logical IP network. Time between hello
packets, in seconds. Range: 1 through 255 seconds Default: 10 seconds; 120 seconds
(nonbroadcast networks)
-
Dead Interval —Specify how long OSPF waits before declaring that a neighboring router is
unavailable. This is an interval during which the router receives no hello packets from the
neighbor. Range: 1 through 65,535 seconds Default: 40 seconds (four times the hello interval)
-
Metric —Cost of an OSPF interface route. The cost is a routing metric that is used in the link-
state calculation. Range: 1 through 65,535 Default: 1
