no ip directed-broadcast <======duh.

Make your ISP do this on their routers so you dont get the smurf from hell on yours.Need more info on this?

By now, you should have www.cert.org drilled in your head.

I think the better command is:

enable

haha
without enable (or en) you won't be doing much :)
but yah, that's a good command :)

this is waaay of the subject, but in yallz opinion, which cisco router...maybe even switch, have you seen in use most frequently? cause im STILL preppin for my ccna. and two, does anybody know how much damn by hand subnetting is on the exam. Its irritating. it took me a serious minute to learn. basics i got, but when i got to stuff like 255.255.255.128, a class friggin b, thoghts of..."whut" appeared in my mind. it sayz that you get 2 subnets for each 3rd octet value. Why..cause my brain is fried like chicken.

Post by: wilnix on April 03, 2002, 04:52:09 PM
No, you have some more reading to do. I think you have subnetting / bits mixed up with your octet count. Go through it again. As far as the what to use to help you with you exam. The Cisco 2501 Router is a much needed tool to help you with your commands. You won't really need to worry much about switching.

Good Luck. BTW: Cisco.com has a little hint of what the exam really looks like. Look under the training section.

I saw Zero replied to this and figured I'd post another command that I thought wasn't here. Come to my surprise that it was the original command. A command which prevents Smurf attacks using your bcaster to attack others, etc. Good choice Will :)

Inbound Vs. Outbound

Is there any simplified explanation as to when setting access control lists on a Cisco router and to these two terms defined?
The sybex cisco book is somewhat confusing on these terms in their definition. And, on my CCNA test, i didnt have to worry about configuring these. On the MCNS, i would think so...well does anybody have a solid and clear definition of what an inbound access list (one would think going INTO the interface/router) vs outbound access list (going OUT OF the interface/router)? At least that is what i thought.

ACLs are per interface. So inbound traffic on e0 could be  going the opposite direction of inbound on s0. Something like this:

            e0                              s0
 --------|-----------------------|--------
-> is inbound on e0                 -> outbound on s0
outbound on e0 <-                 inbound on s0 <-

Hope this helps you.
