Hello,
Your answer was helpfull. Please clarify me the following.. Could you please
comment if I am wright on each of the following points???
1. If I want configure notsostubby area with no-summary. The nssa will
receive only LSA 3 default route. And there is no opportunity to inject in
the nssa the default route to the remote ASs.
2. If I want to inject the default route to remote as's I will have to
configure
area 25 nssa default-information-originate <-- will generate a
Type 7 (N2)
Will the routers in NSSA be able with this default type 7 route be able: a)
reach the IA routes?? reach interAS routes??
3. The command area 25 nssa default-information-originate no-summary does
the same thing as
area 25 nssa no-summary.
4. If using area 25 nssa default-information originate.... should the
default-infromation originate always be configured under router ospf 1 ??
Thanks.
