Hi,
did you find out the answer to this?

The feaure you describe is definately what happens, - but does not happen if
redistributing between say eigrp and ospf?

thanks

Subject: IS-IS and OSPF redistribution

How actually the redistribution works? when we are doing redistribution..
let
say between IS-IS and OSPF... is it only IS-IS/OSPF routes shown in the
routing table is being redistributed. What happen with the connected
interface that we also put that interface into routing domain (in this case
using network command (OSPF) and ip router isis (IS-IS))?

Let say 3 routers

R1 (s1/0.3) --------------- (s4/0) R6 (f0/0) ---------------(e0)R8

R1 and R6 running IS-IS
R6 and R8 running OSPF
The redistribution happen in R6 between OSPF and ISIS.

I cannot ping loopback in R8 from R1.. I know the reason why because the
segment 10.15.0.0 connecting R1 and R6 is not in the routing table fo R8.
The
thing I do no know is why that segment is not in the routing table.. because
I
put already that segment into ISIS routing domain.
