Thanks Ash , thats what I figured. Yes R5 is an ASBR connected to backbone
area 0 and , nssa area 10 , R5 is only ASBR , it is running rip and ospf.
I redist rip into ospf , and on R5 issueing a "show ip ospf database" I
see all the External Type 5's , which should be converted and sent to area
10 nssa internal routers , this was not occuring , I rebooted it and there
it went , I just wasnt sure of the following fact.
1) If I issue a "show ip ospf database" on a ospf asbr which happens to be
an asbr for a nssa area , I thought that all the type 5's I see on this
asbr should be converted into type 7's and sent to nssa internal routers
and show up as type 7's.
