[j-nsp] Question regarding OSPF

[Piotr Marecki]

Ehlo,

External routes have AS scope , so they are not corelated with any area 
whatsoever - you
are misled by the fact that they are displayed at the end , so you think 
that they are now
within area 10 only , which is wrong assumption. They will be always 
displayed at the end of "show
ospf database" output (assuming that router in question has it in database , 
e.g. its not stub/nssa )
and are not specific to any area that was listed before. Also , if you want 
area 0.0.0.10 to not have
LSA3/4/5 you need to defined it as a area stub no-summaries, with 0.0.0.0/0 
injection if required by
including default-metric statement.

regards

Piotr Marecki
