What a job to lay down those suckers. I followed the PPC-1 installation a while back. Its the new submarine cable going into Australia.

Customers Vs. Service-providers.

I wanted to take the opportunity to pitch in on the discussion thats presented in this article by Ivan Pepelnjak: http://blog.ioshints.info/2010/07/p2p-traffic-is-bad-for-network.html with the headline of “P2P traffic is bad for the network”. I agree with the headline… Somewhat… P2P is bad for the network, in the sense that it causes congestion and because of that, it makes using the net a bad experience for everyone else.

IOS Study License

I have vented about this topic before and will do so once again. I am doing this because i believe its very important. Students who are studying for Cisco exams or engineers who are trying to lab up a technology before deploying it, have found Dynamips and used Cisco hardware very useful in the past.

Cisco strategy and direction.

Anyone who has been following Cisco products recently (last year or so), must have noticed Cisco’s new products. This includes the Flip video recorder as well as the new tablet that has just been announced. On top of that, adding the Linksys brand to their portfolio a couple of years ago, proves they are going in a completely different direction than previously.

I wanted to take some time to write up something about the cost of doing the CCIE track. This is prompted by some recent events in the CCIE training community and some discussion on twitter about studying in an economic downturn.

I also managed to do a lot of physical work yesterday, fixing the car up, getting everything cleaned out.

BGP โ€“ Inject-map

I want to point your attention to a great article right here: ardenpackeer.com, good stuff, deffinately worth the read. I am looking this up today, as i ran into it last night doing more BGP labs. Again, just to re-iterate. The feature gives you the ability of taking a network, thats advertised by a certain source, and inject a more specific route of this network into the BGP table (and then to the routing table).

Labs again and again and again.

SNMP traps and NMS

I was just playing around with some switching labs. As i was doing this, i ran into configuring SNMP, sending traps when mac-addresses was added/removed, and all sorts of other things. I could (as in the lab) just set the IP address of the NMS (Network Management System), but i wanted to actually make sure that these were being picked up correctly by an NMS.
