NOTE:
•
If Router C in the NSSA area wants to obtain routes to other areas within the AS, you must configure the
nssa command with the keyword default-route-advertise on Router A (an ABR) so that Router C can
obtain a default route.
• Configuring the nssa command with the keyword no-summary on Router A to reduce the routing table
size on NSSA routers. On other NSSA routers, you only need to configure the nssa command.
