NOTE:
• To allow Switch 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 Switch A (the ABR) so that
Switch C can obtain a default route.
• Configuring the nssa command with the keyword no-summary on Switch A can reduce the routin
g
table size on NSSA Switches. On other NSSA Switches, you only need to configure the nssa
command.
