Hi I had a a previous simulation config backed up trying to achieve what is
required here that is redistributing ia routes into next routing protocols.
============
how did u do the route leaking in the first place...once the routes are
leaked into a L1 area then u dont have to do much to redistribute them into
OSPF downstream from a L1 area.
R1 and R5 are into L2 adjacency. R5 gets some L2 routes and leakes them into
L1 for R6 and inturn R6 redistributes the received "ia" routes into OSPF.
I have omitted most content and just kept two routes constant through out
for clarity.
HTH,
Swaroop
