Configuring IP, ARP, RARP, RIP, and OSPF Services
6-52
308627-14.20 Rev 00
You can configure NSSA type 7 address ranges to allow OSPF NSSA border
routers to control the summarization of external routes for the NSSA (see
“Configuring an NSSA Address Range” on page 6-55). For example, the NSSA in
Figure 1-6 on page 1-17 was configured to import type 7 LSAs through AS
boundary router 15. NSSA border router 11 then translates type 7 LSAs with the
propagate bit set to type 5 LSAs and floods them into all non-stub areas.
Using the BCC
To configure a not-so-stubby area (NSSA), go to the area prompt (for example,
box; ip; ospf; area/0.0.0.1
) and enter:
area-type nssa
To change the default values for NSSA parameters, go to the area prompt and
enter:
<parameter>
<value>
Table 6-8 lists the parameters and values that you can enter.
