CCIE lab static route question
|
|
| Sam Soh 2002-10-30, 10:24 am |
| Is 'ip default-network' command considered as static route in CCIE lab?
Is 'default-information originate always' considered as static route in CCIE
lab also?
What other static route command that is considered as static route?
Thank you.

I think a good rule to follow is anything that shows up with an "S" in the
routing table is a static route.

Sam,
The ip default-network is considered a gateway of last resort, but its
not a static route. A static route would be something like
ip route <ip network> <mask> next hop
ip route 192.168.0.0 255.255.0.0 10.0.0.1.
Hope this helps.

Ooops. Using a non-natural mask creates a static route to null0.
You would have missed all points associated with this section!

Your proctor will answer all questions as to what he/she will and will
not allow you to use.

You lost me... ;-) Is there something wrong with the above command
that I'm missing?

| Hansang,
Please elaborate on this one, please. So 'ip default-network' and
'default-information originate always' are considered as static route? What
do you mean by using non-natural mask to create route to null0? Thank you
very much.

Sam,
The way I understand it, is that a non natural mask will create a
route to null, although I'm not sure that in this case it will. as all
packets destined to 192.168.0.0/24, will go the same direction as
192.168.0.0/16. This static creates a supernet, rather than any
blackholes.
The problem would be much more obvious if the command were
ip route 10.0.0.0 255.255.0.0 192.168.0.1
Any packets destined to 10.1.0.0/16 will be destined through lack of
anywhere better to send them to null.

Sorry, I was mixing up my posts. There are two things you have to keep in
mind when using "ip default-network"
1) The ip default-network that you're referencing must be in the IGP table.
2) You must use its natural mask. So if you put in something like "ip
default-network 172.16.22.0" then the router will automatically create a
static route for 172.16.22.0. If you enter "ip default-network 172.16.0.0"
it will *not* create that static route.
Typically, you have to reboot the router to remove the auto-generated static
route.

| Group,
The thing I concern in here is to know the if wether those commands I
refered below will be considered as static routing and later will be mark
0ff by the proctor in CCIE lab so everything I do on the lab exam going down
the drain. That is all I concern in here. Does anybody know this commands
considered as static routing and cannot be used in CCIE lab?
Thank you
Sam

Static routes are not the only thing that are not allowed. See ksaccent's
posts at www.routerie.com in the CCIE Team Forum.
Default routes generally are also not allowed, as are routes to null0
generated by a routing protocol. If there is a specific
proscription or allowance it is laid out clearly in the lab booklet along
with all the other rules. Also, keep in mind that if you really
can't get something going and other things depend on it you should use a
static route and just get on with it. So what if you lose
a couple points if you still get enough to pass? Obviously it isn't
optimal, but don't throw out static routes entirely if you can't get
it working any other way.

| You cannot use any routing statement to make the default network and static
route.
Proctor will check the any statement in relative to make the static routing
entry and default.

| You can do all sorts of stuff with policy routing to get "static route"
results without resorting to actual static routes. Perhaps they want you to
use these.
http://www.cisco.com/univercd/cc/td...20/12cgcr/np1_c
/1cprt1/1cindep.htm#5027
BTW 'default-information originate' Is certainly NOT a static route. It
generates a LSA type 5 and creates an ASBR.
