current topology and current focus

I think I’ve figured out part of the problem I’ve been having.  I haven’t been entirely focused on my studies, and I don’t really have a set goal right now.  I’ve been dancing with the idea of skipping the CCNP and going straight to the IE written.  Because of that, I’ve been reading chapters in the IE written exam certification guide, chapters in the BCMSN gook, and still reviewing notes, videos, and chapters from the BSCI studies.

With the way work has been going, I haven’t had as much time to study at work, and I don’t have the office space/time to study at home.  I live in a small apartment, and my rack is sitting in my living room.  I may need to bit the bullet and pay for the power consumption to leave the rack running at night.  I can stay an extra hour or so at work after hours to study quietly and access the rack from work.

Either way, I AM going to go for the NP.  I’m spending the next week or so going back through my written notes, watching videos again, and reading chapters in the BSCI book over the next week or so.  I bought the BSCI Lab Portfolio a month or so ago, so I’ll spend the next week going through those labs at night.

The physical topology for the bulk of the labs has four routers and one switch.

These are the routers and switch that I’ve added to the mix.  At some point, I know the lab guide will add the frame switch and possibly another router.  I need to pick up a few extra WIC-1T cards soon.

I made it through the first few EIGRP labs, tonight.  The objectives were pretty basic…

1.  Configure EIGRP on an interface.  simple

r1# configure terminal

r1(config)# int eth fa 0/0

r1(config-if)# ip addr 10.1.100.1 255.255.255.0

r1(config-if)# router eigrp 1

r1(config-router)# network 10.0.0.0

2.  Configure the bandwidth command to limit EIGRP bandwidth

r1(config-if)# bandwidth 64 ! bandwidth in kbps

3.  Verify EIGRP adjacencies

r1# show ip eigrp neighbors

or the alternative and more verbose

r1# show ip eigrp neighbors detail

4.  Utilize debugging commands for troubleshooting EIGRP

r1#  debug eigrp packets ! don’t forget to issue no debug all afterwords.

5.  Challenge:  test convergence for EIGRP when a topology change occurs.

This one was kinda weird.  The preferred path from R3 to a loopback on R1 is going to be via fast ethernet.  The lab has you ping from R3 to lo 3 on R1 with 100,000 pings(this is done using the ping $ip repeat 100000 command).  During these pings, you are to kill R1’s FA interface.  We haven’t modified the variance in EIGRP, and the AD through R2’s serial interface to R1 is more than the FD to lo 3, so the route doesn’t exist in the topology table.

When we killed FA 0/0 on R1, we obviously lost six pings while EIGRP discovered the new route through R2.  What confused me, was when I brought FA 0/0 back up on R1, we lost 33 or 34 pings while while the route through R1’s FA port came back up.

I’ll make it through the remaining EIGRP labs tomorrow night, and hopefully I’ll get through the OSPF labs.  I know there is going to be some slight re-cabling to bring the frame switch back into the mix.  I just hope I have enough WIC-1T interfaces to cover the physical topology change.

route manipulation/BGP

I think I’m coming down with a stomach bug/flu. I’ve been sick all weekend, and was very lethargic all day.
Even still, I made it through the route manipulation/redistribution chapters and labs today. The labs only covered redistributing RIP into OSPF and OSPF back into RIP. nothing with RIP/EIGRP, or EIGRP/OSPF, so I just started doing my own and running lots of debugs and traces to see what might happen.
I’m going to have to read through those sections again just to make sure I’m remembering all of the differences in redistributing the protocols and all the stuff involved with route maps and distribute lists.
I got about 40 pages into the BGP stuff in the authorized self study. I’ll finish that section up this week and double it up with the network academy stuff, as well as the exam certification guide, and hit the labs next weekend. If time permits this week, I’ll hit the multicast stuff, too.

My goal is to have this exam out of the way by February 29th. From there, I don’t want to spend much more than a month or two on each additional NP exam. This is something I should have completed a long time ago, and have had too much happening over the last year to follow through with. NOW is the time.

In other news, a sales manager for Trainsignal contacted me about reviewing some of their materials this week. I live in an apartment with a gate at the entrance. I’ve been in this apartment for a year and a half, and my name still isn’t on the call box. When I found out that the management has decided to close our front gates during the day, I was a little bit miffed. Needless to say, I still haven’t received the materials. I’ve never used VBT/CBT for any tests/certs before. I’m anxious to see how well this training works out.
