OSPF Quiz

Colby — Sun, 23 Oct 2011 20:53:13 +0000

I had an interesting conversation the other day regarding OSPF. I don’t want to give too much away, so here we go. This is the topology: Assume interfaces have correct bandwidth statements and no cost commands have been added. R1 and R2 are redistributing the 192.168.1.0/24 prefix as E2 with a cost of 100. Which…

ASA Bridge Groups

Hello everyone. I know I’ve been neglecting this blog for too long. Can’t promise that things are going to change, but I have a good post for today. I was recently exposed to some new technology while working with a customer. I had to learn it pretty quickly. This post is about a new feature…

Free CCNA Practice Questions

Colby — Wed, 16 Mar 2011 14:23:10 +0000

Steve over at Networking Forum came up with another great idea. He’s offering free CCNA practice questions. He’s asked the members to assist with providing the questions and answers. So far, there are about 30 questions posted, with more to come. They’re all multiple choice, but we’ve included some drag and drop type questions and…

2960s Can Route

Colby — Fri, 11 Mar 2011 14:11:46 +0000

I’ve been meaning to post this for some time. Awhile back there was a thread on Networking Forum where someone mentioned that 2960s can route now. The 2960 is now a layer 3 switch. I was skeptical, but then I was pointed to this link. I was very, very surprised. I’m not sure why Cisco…

Connecting Voice Gateways/CME to the PSTN

Colby — Fri, 04 Mar 2011 13:52:22 +0000

Today we’ll go over the process to connect an IOS voice gateway/CME (Call Manager Express) to the PSTN. I set this up last night and thought it would be a good post. I’ll briefly touch on using a SIP trunk as backup/failover too. I’ve been running a SIP trunk to Flowroute for quite awhile,…

show ip ospf rib

Colby — Thu, 03 Mar 2011 14:57:39 +0000

Another quick one. Today I’m going to cover a simple, but very useful OSPF command: “show ip ospf rib”. This command is similar to “show ip route ospf”, but goes a bit deeper. If you’ve ever done a routing protocol migration, you know how important it can be to see each protocol’s full routing…

Firewall Object Groups

Colby — Wed, 02 Mar 2011 14:29:48 +0000

Dropping in to do a quick post today. Sorry for the ridiculous lack of content lately. I’ve been busy with finding/changing jobs and new responsibilites and all that. Today I’m going to cover “object groups” on ASAs. I was never a big fan of these, which I realized had a lot to do with using…

Testing link/circuit speed using Iperf

Jared — Sat, 18 Sep 2010 22:38:11 +0000

Hi all! It’s Jared from CCNPJourney.com. Colby had asked me a couple weeks ago if I would be interested in posting some articles on his blog as he’s been fairly busy lately, and of course I said yes. So I thought for my introductory post on the blog I would do a brief write-up on…

CCNA Scholarship

Colby — Fri, 17 Sep 2010 02:19:42 +0000

Steve is doing another generous offering over at Networking Forum. He’s planning to give away a “scholarship” for the CCNA. He will essentially pay someone’s way through the CCNA if this person agrees to log his or her progress on the forum. We, the staff and member base, are also offering our guidance and support…

Fiber Woes

Colby — Tue, 07 Sep 2010 15:28:44 +0000

I’m in the process of doing a very large hardware refresh for my company. We’re replacing 100+ old/EOL switches throughout the network/country. This shouldn’t be too big of a deal, but the latest generation of Cisco switches use SFPs. The older stuff is all GBIC. For most of our large sites, this isn’t major as…
