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