All-
I need some help in figuring out what this route map is doing.... R5 is the
hub router in this excercise.R4 is a PtoP spoke runnning IGRP. R5 is running
IGRP and OSPF and doing mutual redistribution between the two.
Here is my head scratcher,........ The lab answer has route-map filter_igrp
in its redistribution statement. Why? As I see it, none of these routes
would be fed into IGRP anyway because of the different subnet mask than the
IGRP is using,..... What am I overlooking?
Anyone else run into this???????
R5:
