NIST blesses network access, desktop security Posted: 28 Sep 2010 09:00 AM PDT The Trusted Computing Group and the National Institute of Standards and Technology Tuesday joined to give their blessing to the union of two technologies that each have championed: TCG with its network-access control standard called Trusted Network Connect, and NIST with its desktop-security configuration standard called the Security Control Automation Protocol. |

Google: friendly giant, benevolent despot? Posted: 28 Sep 2010 09:00 AM PDT When Google first found its way into the public consciousness it was as a quirky but effective service: a simple search tool that cocked a snook at the monolithic giants of the PC industry. Its 'Don't be evil' slogan and unusual working practices made Google seem like a creative breath of fresh air, churning out innovative free products and enjoying positive PR that the likes of Microsoft and IBM would kill for. |

CCNA Wireless - Any netsims available? Posted: 28 Sep 2010 08:23 AM PDT Hi, I am a CCNA and looking to recertify by taking the CCNA Wireless concentration as I would like to add some new knowlegde rather than just retake the current CCNA. I will need to know how to configure Cisco WCS, WLC's and AP's for the exam, so I am looking for a netsim like Boson's but for the Wireless config's only. Does a netsim for CCNA Wireless exist and if so what is it and how do I get it? Thanks. |
Redistribution : Rip & OSPF Using Packet Tracer Posted: 28 Sep 2010 08:29 AM PDT I was playing around with Packet Tracer today, thought why not give it a try. Nice program none the less. So here is a very modest try on basic redistribution. I thought it will help someone. The lab had very basic set up, i used three routers and with a bunch of loopbacks i tested the redistribution between RIP and OSPF. You can use this lab as a tester or a reference point. PT lacks a lot of command options but is still very highly usable. So here is the setup: Router 1: (RIP V2) interface Loopback1 ip address 192.168.10.100 255.255.255.0 ! interface Loopback2 ip address 2.2.2.2 255.0.0.0 ! interface Serial0/0 ip address 172.16.10.1 255.255.255.252 ! router rip version 2 network 2.0.0.0 network 172.16.0.0 network 192.168.10.0 no auto-summary Router 3: (OSPF 1) interface Loopback1 ip address 3.3.3.3 255.0.0.0 ! interface Loopback2 ip address 192.168.20.100 255.255.255.0 ! interface Serial0/0 ip address 172.16.20.1 255.255.255.252 clock rate 64000 ! router ospf 1 log-adjacency-changes network 3.3.3.3 0.0.0.0 area 0 network 192.168.20.0 0.0.0.255 area 0 network 172.16.20.0 0.0.0.3 area 0 Router 2: (Performed the redistribution) interface Serial0/0 ip address 172.16.10.2 255.255.255.252 clock rate 64000 ! interface Serial0/1 ip address 172.16.20.2 255.255.255.252 ! router ospf 1 log-adjacency-changes redistribute rip subnets network 172.16.20.0 0.0.0.3 area 0 ! router rip version 2 redistribute ospf 1 metric 5 network 172.16.0.0 no auto-summary Outputs: Router 1: (Rip) Gateway of last resort is not set C 2.0.0.0/8 is directly connected, Loopback2 3.0.0.0/32 is subnetted, 1 subnets R 3.3.3.3 [120/5] via 172.16.10.2, 00:00:01, Serial0/0 172.16.0.0/30 is subnetted, 2 subnets C 172.16.10.0 is directly connected, Serial0/0 R 172.16.20.0 [120/1] via 172.16.10.2, 00:00:01, Serial0/0 C 192.168.10.0/24 is directly connected, Loopback1 192.168.20.0/32 is subnetted, 1 subnets R 192.168.20.100 [120/5] via 172.16.10.2, 00:00:01, Serial0/0 Router 3: (OSPF) O E2 2.0.0.0/8 [110/781] via 172.16.20.2, 00:18:56, Serial0/0 C 3.0.0.0/8 is directly connected, Loopback1 172.16.0.0/30 is subnetted, 2 subnets O E2 172.16.10.0 [110/781] via 172.16.20.2, 00:18:56, Serial0/0 C 172.16.20.0 is directly connected, Serial0/0 O E2 192.168.10.0/24 [110/781] via 172.16.20.2, 00:18:56, Serial0/0 C 192.168.20.0/24 is directly connected, Loopback2 Router 2: (Performed Redistribution) R 2.0.0.0/8 [120/1] via 172.16.10.1, 00:00:00, Serial0/0 3.0.0.0/32 is subnetted, 1 subnets O 3.3.3.3 [110/782] via 172.16.20.1, 00:20:15, Serial0/1 172.16.0.0/30 is subnetted, 2 subnets C 172.16.10.0 is directly connected, Serial0/0 C 172.16.20.0 is directly connected, Serial0/1 R 192.168.10.0/24 [120/1] via 172.16.10.1, 00:00:00, Serial0/0 192.168.20.0/32 is subnetted, 1 subnets O 192.168.20.100 [110/782] via 172.16.20.1, 00:20:15, Serial0/1 (The routes that are in bold are learned using redistribution) Now you could use the "passive-interface" command on s0/1 of Router 2 so that route on s0/1 is advertised by RIP. If you want the PT lab file, here is the link: hxxp://[nofileshares].com/files/195399030/redist-lab1.pkt.html Note: As i mentioned above PT does lack some of the advance features. For example while redistributing the rip i was not able to specify the metric-type. But as you can see it still works. |
What CCNA1 labs have you encountered so far? Posted: 28 Sep 2010 08:13 AM PDT Hello, I'm curious: what CCNA1 labs have you encountered so far? At CCNA1 I played with: - wireshark for packet capture - cain for interesting demonstrations - packet tracer for simulating networks - let's not forget the subnetting labs and wiring cables - another "lab" is playing a game like "Jeopardy" with questions from the it section What other interesting activities have you done so far on your CCNA1 classes? I'm looking for ideas to spice a little my CCNA1 class, so any crazy idea is very welcomed! Thanks in advance! |
