Therefore, effective November 4th, 2002, the following topics will no
longer be tested on the CCIE Routing and Switching exam:
IGRP

Token Ring Switching
IPX
Please note that DLSw+ will remain as a valid topic on the exam.

Subject: RE: ISIS / OSPF Redistribution
Are you studying ISIS for the CCIE lab? I thought ISIS was no longer a
requirement.

Subject: ISIS / OSPF Redistribution
I am having problems with redistributing ISIS routes into OSPF for some
reason. Here is the scenarion:
R2(area A) L2 / R3(area B) L1-2 / R5(areaB) L1 are ISIS routers. I have
OSPF running on R1/ R3/ R4 all in area 0. The problem is that the route
generated from R5 (ISIS L1) 162.1.1.0/24 is not getting redistributed
into OSPF at R3 which is performing mutual redist.
Here is the layout:
R5

R2 R3

R1 R4
Here is some out put from router 3 then I'll post the configs:
r3#sh isis data det [THIS shows that the route is in R3] as well as
the sh ip ro
