Yes, the network type must match!! I know because this is exactly what
killed me on my first attempt. I even asked that question to the proctor
who confirmed (without directly answering the question) that the network
types MUST match, even if the timers are the same.
You would only need to use the "neighbor" statement on a NBMA network such
as frame relay.

RE: Soile's Skynet Labdoes the network type have to match for the router to
form adjacency? I think not, but if I am wrong please explain... I think
that
if the timers match, the network type can be different (altough it will make
you use "neighbor" statements if using different network types, but thats
another story).
Otherwise, Skynet lab would be impossible to do, once you have to form
adjacency between the routers, with the hub using subinterfaces and the
spokes
using physical interfaces, without using the "ip ospf network" command...

Correct! The OSPF timers must match for all routers in the area and the
OSPF network type must match for the routers to form adjacencies.
You can change the OSPF network type with the "ip ospf network
<networktype>" interface command, if you need to.
Sorry, I'm not sitting in front of my routers right now so I'm not sure if
that is the correct syntax. Someone PLEASE correct me if I'm wrong on that
syntax.

I have not done Solies yet, but I know you do have to make all the
timers
match in OSPF for adjencies to form, however I do not think that simply
making
timers match is a solution to differeing OSPF network types. Is that
correct??

Persio,
Read the thread on OSPF Dead Interval.
If you change only the hello timer all the other timers are
automatically
updated.

Folks,
going through Soile's Skynet lab, I came upon one doubt: You are
supposed to
chenge the OSPF Hello timer to 60s on R3. Also, you are supposed to
overcome
the different network problem between R1, R2 and R3 without using "ip
ospf
network", and by this, you have to change also the timers. It's okay
then
that
the three routers agree upon 60s hello timers.
My question is: shoudn't the dead timers be changed as well? I am
asking
this
because on the Skynet solution guide, there's no change on the dead
timer
for
any router.
Regards,
Persio
