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 throughout the process. Here’s a snippet from the forum:
What’s going on?
networking-forum.com is offering a scholarship to one person who would like to earn a Cisco Certified Network Associate (CCNA) certification. The scholarship will provide the CCNA Official Exam Certification Library, a separate forum specifically dedicated to the candidate for his or her use during their studies with feedback from the site’s members, and reimbursement of the exam fees after they pass their exam(s).
How is the recipient chosen?
Greg at Etherealmind has created a petition for an educational IOS version. Details:
We the undersigned ask you to sign our petition.
We are the people who are learning about Data networking and Cisco IOS software. As students and practitioners, we need to learn theory and knowledge and then to take that knowledge and practice on Cisco IOS software.
We want to be able to practice that knowledge, and demonstrate our competence. We know that you are considering the value. This petition is to show our need for this solution. Wendel Odom discusses the possibility Cisco Considers IOS for Certifcation Self Study and we are calling for Cisco to make an option available.
This experience and knowledge we gain gives us the capability to make the most of Cisco equipment for our employers, your customers. We help drive the best return on investment, and keep the network performing in the way that your customers expect.
Sorry for the horrible lack of updates lately. I had to shift focus a bit to meet a job requirement. It’s come down from the top that everyone in the North American Network group within my company needs to get the ITILv3: Foundations cert by September of this year (ugh!). I’ve been cramming it like crazy and hope to knock the exam out in the next couple weeks. If that all works out I can get back to Cisco stuff and hopefully some decent posts.
If anyone is curious about ITIL, it’s terrible, lol. Supposedly it’s a valuable cert, so I can’t complain too much, but it’s just so boring. I love networking, so Cisco certs are actually fun for me. ITIL is just painful.
Anyway, check out my blogroll to get your networking fix.
This post is about OSPF Summarization. We’ll be using a familiar topology and going over two ways to summarize with OSPF.
There are two conventional ways to summarize networks in OSPF, we can use the “area range” command and the “summary-address” command. “Area range” is used on the ABR to summarize networks between areas. The “summary-address” command is used on the ASBR to summarize external networks.
Here’s the topology:
I’m not going through the basic OSPF config, so assume everything is configured as the diagram suggests. On R1 I’ve added Lo11-14 and used “ospf 100 area 0″ under the respective interfaces. On R2 I’ve added Lo15-18 and used “redistribute connected subnets”. Let’s look at the RIBs on a couple routers:
First we’ll check out “sh ip route” on R1:
R1#sh ip route ... 220.127.116.11/32 is subnetted, 1 subnets C 18.104.22.168 is directly connected, Loopback0 22.214.171.124/32 is subnetted, 1 subnets O E2 126.96.36.199 [110/20] via 10.1.123.2, 01:13:32, FastEthernet0/0 188.8.131.52/32 is subnetted, 1 subnets O E2 184.108.40.206 [110/20] via 10.1.123.3, 01:12:38, FastEthernet0/0 220.127.116.11/32 is subnetted, 1 subnets O E2 18.104.22.168 [110/20] via 10.1.123.3, 01:03:47, FastEthernet0/0 172.30.0.0/24 is subnetted, 4 subnets O E2 172.30.6.0 [110/20] via 10.1.123.2, 00:06:11, FastEthernet0/0 O E2 172.30.7.0 [110/20] via 10.1.123.2, 00:06:11, FastEthernet0/0 O E2 172.30.5.0 [110/20] via 10.1.123.2, 00:06:11, FastEthernet0/0 O E2 172.30.8.0 [110/20] via 10.1.123.2, 00:06:11, FastEthernet0/0 C 192.168.4.0/24 is directly connected, Loopback14 10.0.0.0/24 is subnetted, 2 subnets O IA 10.1.34.0 [110/74] via 10.1.123.3, 01:12:39, FastEthernet0/0 C 10.1.123.0 is directly connected, FastEthernet0/0 C 192.168.1.0/24 is directly connected, Loopback11 C 192.168.2.0/24 is directly connected, Loopback12 C 192.168.3.0/24 is directly connected, Loopback13
Lots of routes here. The ones to note are the 172s showing as External Type 2, which are R2′s loopbacks. Also notice our connected loopbacks.
