The specified area is configured as a stub area.
NOTE
l All switches in a stub area must be configured with stub attributes using the stub command.
l Configuring or deleting stub attributes will update routing information in the area. Stub attributes can
be deleted or configured again only after the routing update is complete.
Step 5 (Optional) Run:
stub [ no-summary ]
The ABR is prevented from sending Type 3 LSAs to the stub area.
Step 6 (Optional) Run:
