Why Can't I Skip My Twenty Minutes of Reading Tonight? (shared on mailring by Emmy Ellis: source unknown) came via my granddaughter's 2nd grade teacher. I was so happy to receive it and want to share it with you too!
Why Can't I Skip My Twenty Minutes of Reading Tonight?
Let's figure it out -- mathematically!
Student A reads 20 minutes five nights of every week;
Student B reads only 4 minutes a night .. or not at all!
Step 1: Multiply minutes a night x 5 times each week.
Student A reads 20 minutes x 5 times a week = 100 mins./week
Student B reads 4 minutes x 5 times a week = 20 minutes
Step 2: Multiply minutes a week x 4 weeks each month.
Student A reads 400 minutes a month
Student B reads 80 minutes a month
Step 3: Multiply minutes a month x 9 months/school year
Student A reads 3600 minutes in a school year
Student B reads 720 minutes in a school year
Student A practices reading the equivalent of ten whole school days a year. Student B gets the equivalent of only two school days of reading practice.
By the end of 6th grade if Student A and Student B maintain these same reading habits, Student A will have read the equivalent of 60 whole school days.
Student B will have read the equivalent of only 12 school days.
One would expect the gap of information retained will have widened considerably and so, undoubtedly, will school performance. How do you think Student B will feel about him/herself as a student?
Some questions to ponder:
Which student would you expect to read better?
Which student would you expect to know more?
Which student would you expect to write better?
Which student would you expect to have a better vocabulary?
Which student would you expect to be more successful in school... and in life?

Cisco Router/PIX Emulator
I have been hearing so much about Dynamips lately that I think I must take some time to do some experimenting with it. I just received an email from a COD friend and Alumni, Gonzalo Escarra, a Sr. Technical Support Analyst for Aqueity, and he writes:
“As I'm studying for my CCNP now, I found this new Cisco emulator based on Dynamips and PEMU called GNS3 (http://www.gns3.net/). It's a GUI for building a lab using Routers and PIX's, and it works flawlessly on Windows. The only thing you'll need are the IOS images to run, as the software uses original Cisco images to emulate (meaning you get the exact same functionality in a lab environment).
Figured you might be interested to pass this along to your students in case they need some extra practice outside of lab time. It is VERY useful at least for me.”
Maybe we should form a Dynamips workgroup and figure this out together. Let me know via email if you would be interested. Gonzalo has volunteered to give us some support just in case we run into problems.
Thank you Gonzalo!

RIPv2 Next Hop Address
Remember on the RIPv2 PowerPoint slide (as shown) we were seeing on the debug ip rip a 0.0.0.0 address and couldn't explain why. Steven Zinkie jumped right in on this and reported back with the answer. He found the following explaination in our book..
1) Like RIPv1, RIPv2 is encapsulated in a User Datagram Protocol (UDP) segment using port 520 and can carry 25 routes per update.
2) The first significant extension in the RIPv2 message format is the subnet mask field (32 bit mask) to be included in the RIP route entry.
3) The second significant extension of RIPv2 is the addition of the next-hop address. The next-hop address is used to identify a better next-hop address – if one exists. If the field is set to 0.0.0.0, the address of the sending router is the best next-hop address.
Thanks Steven - mystery solved!

RIP Default Routes: default-information originate vs. redistribute static
I told my students that the default-information originate command was similiar to the redistribute static command. A student asked me how exactly do they differ. To answer that question I have set up a scenario using three routers, as depicted above, to give studens a visual of how they both work and differ.
I set up Router3 as the ISP and configured two static routes pointing to 10.1.1.0/30 and 192.168.1.0/24. I set up Router2 as the edge router of my network. In Router2 I had two static routers pointing to virtual networks (network 1.0.0.0 and network 2.0.0.0) and a default static route (0.0.0.0).
First I configured Router2 to propagate the default route to Router1 using the default-information originate command. As a result, the default static route was propagated correctly to Router1 as shown below (see Router2’s configuration file, routing table and Rotuer1’s routing table). Notice that the default static was the only static route that RIP advertised to Router1. Note, I have removed some unrelated lines of commands from the configuration files, to simplify.

R2 is the edge router which contains two static routes and a default static route. The default static route has been propagated to the inside (R1) using the default-information originate command.

R* 0.0.0.0/0 [120/1] via 10.1.1.2, 00:00:13, Serial0/2/0R1#
Next, I configured Router2 to propagate the default route to Router1 using the redistribute static command. As a result, not only the default static route was propagated Router1, but ALL three of the static routes were advertized to Router1! See Router1’s routing table after modifying R2’s configuration file to use the redistribute static command in place of the default-information originate command:
R1#show ip route
Gateway of last resort is 10.1.1.2 to network 0.0.0.0
R 129.5.0.0/16 [120/1] via 10.1.1.2, 00:00:04, Serial0/2/0

R* 0.0.0.0/0 [120/1] via 10.1.1.2, 00:00:04, Serial0/2/0
R1#
As you can see, since R2 had more that one static route, they were all advertised through RIP using the redistribute static command. Therefore, in order to use the redistribute static command, we need to do some additional configuration to Router2. In Router2, we would have to use a distribute-list command or a route map (both to be studied in your CCNP1 class) to permit only the default static route to be propagated by RIP. Following is an example of the extra configuration needed in Router2 as well as the resulting Router1 routing table.
