So I'm plucking through the Simplified book for route and am making notes of things to come back and lab (might add I had I have picked up on many grammatical / typos in the book). Yet I really do enjoy the layout and the general explanations of the book. I just have a slight worry in the back of my head that the commands I am typing might not be correct from the example due to the number of errors I have found.
Anywho, I am working on a scenario explained in the book (page 328 if you have it)
Basically the objective is to filter R2 the ABR from sending specific routes / Summary LSAs from Area 0 (R1) routes to the remainder of the OSPF domain. Specifically the 192.168.1.1 and 192.168.1.3 networks. Well I have checked, re-checked, and triple checked my commands and can't seem to pinpoint why this is not working.
R3 appears to be still learning all the routes / summary LSAs from R1 (area 0) via R2 the ABR into Area 1.
Here are the configs and topology.
