Ok, getting back to where I left of in April (gasp!) – with OSPF Router ID , lets continue with OSPF Authentication.
Keep in mind that these posts actually build off the previous posts, so you may need to review the others again.
First up, our topology for this lab:
Ok, time for some OSPF Authentication. First up, link authentication!
We will configure authentication on the link between J1 and R4.
R4 up first!
Are you a Grinch when it comes to hanging christmas lights? Hate doing it as it takes too long or you do not like getting on the roof? Well, I am in the same boat – but I love how they look on the house and the kids love them!
A few years ago I had a Christmas Light bulb go off in my head. I have worked on this idea for about 3 years now and I think I finally have it ifgured out.
Here is how I put Christmas light up now!
With zip-ties, PVC, and J-hooks! Say what? Well, here is how it all works.
You will need (besides your christmas lights)
– 1/2” PVC Electrical Conduit 10′ Secions
– Zinc Plated 5 1/16 x 3” J-Hook and bolt (3 hooks per 10′ section)
– Zinc Plated 5/16” Nylon lock nuts (1 lock nut per j-hook)
– Outdoor Zip Ties (lots!)
Some time ago, not sure how long ago, Cisco started a Cisco Champion program for people who are passionate about Cisco and active on social media ( twitter, Facebook, Google Plus, etc). I am glad to say that I and flattered and honored to be called a Cisco Champion Data Center.
Taking some words from the Champion site – http://www.cisco.com/web/about/facts_info/champions.html#~overview, , the Cisco Champion program is:
What makes a Cisco Champion? Passion, plus a desire to share their perspectives with the community. There are Cisco Champions all over the world. They represent a variety of segments across the IT industry. And they offer their time to help others learn about Cisco and connect with Cisco in unique ways.
In addition to sharing their insights and expertise, Cisco Champions make a difference by:
Was just looking through the Cisco MIBs again and found a few things that I wanted to share
I do not fully know what they mean or may lead to, but my initial impression is a few new routers on the horizon.
Right from the MIB, here are some new Router models:
ciscoitpRT1081K9 OBJECT IDENTIFIER ::= { ciscoProducts 1952 } — Router 1081 Fast Ethernet Router
ciscoitpRT1091FK9 OBJECT IDENTIFIER ::= { ciscoProducts 1953 } — Router 1091 GigaE SecRouter
ciscoitpPwr30WAC OBJECT IDENTIFIER ::= { ciscoProducts 1954 } — Power Supply 30 Watt AC
ciscoitpPwr60WAC OBJECT IDENTIFIER ::= { ciscoProducts 1955 } — Power Supply 60 Watt AC
ciscoitpPwr60WACV2 OBJECT IDENTIFIER ::= { ciscoProducts 1956 } — Power Supply 60 Watt AC
ciscoitpPwr125WAC OBJECT IDENTIFIER ::= { ciscoProducts 1957 } — POE power supply
Some time ago I started to post some Juniper configurations based on a workbook that I was working on. It has been too long since I have followed up with those posts and it is time for me to get back to them.
Here is what you can look forward to in the coming weeks from the Juniper Series:
More OSPF – Authentication, Stub, OSPF/RIP
iBGP – Route Reflector, Juniper and Cisco
November was a busy month for me on the job front as well as personal vacation. What also happened is that I was a paid Solar Winds Thwack Ambassador for the month (Nov 2013) as well and posted some fun and intersting items.
I wanted to take a moment and share them with you in case you did not get a chance to view them prior
My first post was Network Topology Horror Stories – http://thwack.solarwinds.com/thread/60335
There are some great stories in this post, just wow sometimes!
The second post was Application Intelligence in the Network – http://thwack.solarwinds.com/thread/60485
This post was right after the Cisco, Arista, and Juniper announcements in November.
Third was What Tips and Tricks do you have for Networking – http://thwack.solarwinds.com/thread/60838
Some great ideas in this post, really worth checking out!
And my final post for the month was What Network Support and Troubleshooting Are in your Software Toolkit? – http://thwack.solarwinds.com/thread/60636
Again, some great ideas and software tools to check out!
Check them out and share your information and stories if you like!
Ahh, restart – reboot – start again – however you look at it, that is what I just did … again.
I am not one for changing companies, but this time I was left with few options. You see, Torrey Point was acquired by another company back in November. The acquisition was under friendly circumstances, but the onboard process that I experienced was not inviting to me. Not sure if it was the new companies fault or some external factors that cause it, but regardless it left me feeling cold.
During the time of the acquisition negotiations I was contacted by Dimension Data and asked if I was interested in joining them. Being that I used to work with Dimension Data when I was at the enterprise, I already knew a few people who worked there. After a quick lunch with an old co-worker who works there (he is a VP) and some phone calls, an offer letter was extended to me and I accepted.
Just wanted to put out a quick post. I have moved the site from my old hosting provider to Digital Ocean. I am still in the process of the migration, so some images may not be working. I am trying to ferret through all the posts to find and fix the missing images. Please be patient while I work on this.
I moved the site for two main reasons – first reason being that I left my employment at TorreyPoint / Fishnet Security and was hosted by one of their customers. The second reason is that Digital Ocean uses SSD for their servers and their prices are really good. They have plans that start at $5 month for a server with 512M and 20G SSD drive – that is perfect for a blog!
Back at Cisco Live 2013, there was some chatter around the Insieme deal and the potential to see a new switch from Cisco during the event. I think even Greg over at EtherealMind was hoping for some more juicy Insieme announcements at Cisco Live as well ( see post – http://etherealmind.com/musing-predicting-what-insieme-might-announce-at-cisco-live/ )Well, what we actuall got at Cisco Live was the Nexus 7700 switch and the Gold Cisco 6608 Catalyst Switches, not the hoped for Insieme switch.
Then today I saw that there an article posted over on NetworkWorld ( http://www.networkworld.com/news/2013/100213-interop-cisco-insieme-274455.html ) in regards to the Insieme Nexus 9K and Hardware Defined Networking that caught my attention. There is another article there – http://www.networkworld.com/community/blog/cisco-nexus-9000-aimed-40g – that has some output from a 9508 switch as well.
Ok, not new information but kind of new information to share.
Back in June during Cisco Live Orlando 2013 during the session BRKARC-2003 – Cisco ASR9000 System Architecture there where some slides that discussed a couple new ASR9000 series routers, the ASR9904 and ASR9912.
The ASR9904 is supposed to be released in October ’13, and that happens to also coincide with the rumored IOS-XR 5.1 release of code. Well, to date only the ASR9912 has been announced ( http://www.cisco.com/en/US/products/ps13288/index.html ), but with the recent release of the IOS-XR 5.1 Release Notes on Cisco’s website, the ASR9904 is listed there as can be seen in a snippet from that file: ( the original pdf release notes can be found here http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r5.1/general/release/notes/reln_510a9k.pdf )
