Ok Im going to bite the bullet. I've labbed this up a few times, with the
same results, even mixing up the media...same.
I've been doodling with ISIS some. Topology is this:
/ ---R2
R4----Ethernet-----R1------Frame --|
\---R3
R4 runs only ISIS.
R1 runs OSPF and ISIS, and mutually redistributes.
R2 & R3 run OSPF only.
I've advertised R1/R2/R3 loopbacks into OSPF.
R4's loopback has been advertised into ISIS.
I can see all routes everywhere. From R1/R2/R3, I can ping R4 no problem.
From R4, even though I can ping everywhere - I can only ping R1.
I've even extended this network will past R3, adding like 3 more links past
it. It will get R4's route there, and also be able to ping it.
But not vice-versa.
Now, to ask the stupid question, why?
I've peeked thru the archives some, but in vain. I did run across some
info concerning ISIS and that it doesn't advertise connected networks (or
was that redistribute) by default. This isn't the type of problem I'm
having, as I'm seeing all routes advertised everywhere. It seems like this
problem may have been fixed in 12.2 anyway, as this was pretty far back, if
I remember correctly.
So someone please tell me I've messed up something simple ! I can lab it
up again this evening and provide configs if necessary.
