Parameters
default-route-advertise-always: Used only on a stub ABR. With this keyword, the ABR advertises a
default route in a Type-3 LSA into the stub area regardless of whether FULL-state neighbors exist in the
backbone area. Without this keyword, the ABR advertises a default route in a Type-3 LSA into the stub
area only when at least one FULL-state neighbor exists in the backbone area.
no-summary: Used only on a stub ABR. With this keyword, the ABR advertises only a default route in a
Type-3 LSA into the stub area without advertising any other Type-3 LSA. The area is a totally stub area.
Usage guidelines
To remove the default-route-advertise-always or stub no-summary configuration on the ABR, execute the
stub command again to overwrite it.
To configure an area as a stub area, issue the stub command on all routers attached to the area.
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
