Parameters
default-route-advertise-always: Enables the ABR to advertise a default route in a Type-3 LSA into the stub area regardless of whether FULL-state neighbors exist in the backbone area. If you do not specify this keyword, the ABR advertises a default route in a Type-3 LSA into the stub area only when a minimum of one FULL-state neighbor exists in the backbone area.
no-summary: Enables the ABR to advertise only a default route in a Type-3 LSA into the stub area without advertising any other Type-3 LSAs. The area is a totally stub area.
Usage guidelines
To configure an area as a stub area, use the stub command on all routers attached to the area.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Configure Area 1 as a stub area.
<Sysname> system-view [Sysname] ospf 100 [Sysname-ospf-100] area 1 [Sysname-ospf-100-area-0.0.0.1] stub
