my soho is now an ospf network...
how?
went to router 3 and added ospf (router ospf 3, the 2 networks)
same to router 2 and added the 2 directly connected networks,
then router 1 and it's 4 directly connected networks,
then went back and whacked eigrp on each router,
hopped over to the 3550, added ospf and it's directly conected networks, whacked eigrp, and
now everybody is pinging everybody...
took about 5 minutes...

xmodem...
i was getting tired by the last router upgrade from smi to emi...
but first a moment from our sponsor, the 3550 switch...
the default baud rate out of the box is 9600 for a console connection, however, did you know that this cannot be changed using the configuration register... 3560's either... so i have what appears to be a baud rate incompatibility with my console connection because after setting the term to 9600, 8, none. 1, i get weird ascii creatures... that's a pain in the ass... hope i don't end up in rommon mode after next reload...
back to the ios upgrade... i delete the current ios in flash, copy run start, and reload the router...
shit...
after it came back it couldn't find an ios... flash was empty... i should have gone to bed... like i said, i was tired... it's been years since i've done an xmodem ios transfer... i set the baud rate on the router to 115200 and xmodemed away... 2 hours later i finally had an ios in flash again... duh...
here's the key... don't be a hero and delete flash from the cli by hand... let copy tftp flash do it for you... it will prompt you to erase before loading the new ios, and you won't be sitting there all night watching exclamation points go across your damn screen because you bounced the router before you loaded the ios...

a snap of CMS...
the 3550 i got yesterday on CMS... more later... it's simply embarrassing in light of uber-geek...
Wednesday, November 2, 2011
a new beginning...
my first shipment arrived today, the 3550, i expect the rest of the gear tomorrow... it's kind of weird having the shit in my apartment... it'll be a constant reminder; configure me, connect me, make me go to porn sites... i'll do pictures tomorrow once i have them racked...
so i take the switch out of the box, set it on a stand for now, grab the console cable and i'm ready to connect it to my laptop... no serial port... not a problem... i break out the old desktop, monitor, etc, power it up and i'm all set... no serial port on that either and that's got to be five years old by now... damn... off to office max, nice that it's just up the road, and i look around a bit... over ten bucks for a power cable, nearly thirty for a long rj-45... i turn a corner and there is the section i'm looking for... 37 dollars for a serial to usb adapter... i have these visions that i'm about to nickel and dime myself into the poor house with this project... all right, buy it, return it before 14 days are up, and get a cheaper one on line... not a chance, 30 bucks on line not including shipping... good God...
had to install software for it also... connect it up, run putty, select serial, com1, defaults to 8, none, and 1
and i get errors; serial port not found... go to control-panel, system, hardware, (xp machine) and there it is... on com3...
works great... connected it up through the wireless router to the cable modem and i'm pinging the time warner gateway within moments... routers and more switches tomorrow...

my plan...
i am setting up a lab comprised of 3 2610xm routers, a 3550 layer 3 switch, 2 2950 switches and all the cables... basically, a ccnp lab in which i will share lab experiences, lab set ups and anything else i bump into along the way... all things useful that i find towards a certification end, i will post... i will continue to share networking experiences i've had over the past twenty years, as well as any tips or help i may be able to provide... test questions, labs, trial and error, etc...
a word on braindumps... don't waste your time... trust in the materials within your reach... do it legitimately and it will be worth it in the end... there are no shortcuts...
please post any and all comments or suggestions and feel free to email any time... any difficult areas you might have with study materials, test questions, et al...
this will help me in my quest, and hopefully, this will help in yours...
