Hi GS,

I am trying to understand what the OSPF command:

Area 1 nssa translate type7 suppress-fa

As far as I know nssa allows for translation of type 7 to type 5 LSA's and
this is achieved just by defining the OSPF area as an "nssa". While doing a
mock lab a requirement was made to suppress the original (type 7) advertiser
address. I have checked a backbone router which is not an ABR for the NSSA
to see who is the advertising router of the translated type 7 routes (the
type 5 ) - the adv ID was that of the NSSA ABR. I have added and removed
the command "Area 1 nssa translate type7 suppress-fa" sevral times. While I
saw the Seq number increased in the OSPF database, there was no change in
the LSA data.
From what I can understand this command does nothing.
What does this command do, I have read the DocCD a several time, and I cant
make it out . Please Help

Thanks in advance

Eli
