I understand the new Cisco exams are now available to sit, but I've been studying currently for the 640-802. Im looking to progress through my CCNA Security and CCNP Security eventually but I'm not entirely sure which exam's I should pursure.

Am i better off starting with the new 100-101 ICND1 then going straight onto 640-554 IINS to achieve my CCNA Security or should I continue revising and sit the 640-822 ICND1, them the 640-816 ICND2 to achieve my CCNA, from there taking the 640-554 IINS to get my CCNA Security, or can I do my 640-822 ICND1 then go straight onto the 640-554 IINS and achieve the CCNA Security?

Im rather confused still upon how the new Cisco qualifications tie in with the old. :confused:

I'm trying to figure out a weird routing issue I'm experiencing, I will lay it out for you guys hoping someone could help me sort this out.

At a branch office we have a [Primary Router] & [Backup router] learning some routes via ospf. The problem is on the backup router, while the primary is dynamically learning these routes via ospf, the backup is learning them via bgp through the PE that is facing this bck router.

[PE]-----------------------------[PE]
| |
| |
| |
[Pri Router] [BCK Router]

The backup router had this routes configured statically before, when they were removed they started to be learnt via ospf now when you perform a clear bgp they started to be learn from its neighbor PE via bgp instead of ospf. We configured them statically and remove them to they start to be learn via ospf now what I'm afraid is that if this backup circuit goes down or someone reboots the router they will go back to be learn via bgp. isn't this weird?

any advise will be greatly appreciated. ]]> Routing n3twrk0p http://www.lammle.com/discussion/showthread.php?t=6214 Chapter 8 Pg 374/375 http://www.lammle.com/discussion/showthread.php?t=6213&goto=newpost Thu, 09 May 2013 04:56:30 GMT I'm using CCNA Virtual Lab to set up Fig 8.10 internetwork.

After adding the static routes 192.168.10.0 and 192.168.20.0 to Router Corp, I have no problem pinging to the Finance PC and the Marketing PC from Router Corp.

What bothers me is when I removed one of the above two routes, for example, when I remove ip route 192.168.20.0 statement from Router Corp, why am I still able to ping to the Marketing PC successfully?

Show ip route reveals 192.168.10.0/24 is connected via 10.1.2.2 while the other ip route 192.168.20.0/24 via 10.1.3.2 is no longer available which is expected.

I would appreciate very much if you can help me to understand how does Router Corp know that it is possible to reach 192.168.20.1 (Marketing PC) via 10.1.2.2 when its routing table now only has the ip route to the 192.168.10.0/24 network? ]]> Chapter 8: IP Routing jacklim http://www.lammle.com/discussion/showthread.php?t=6213 CCENT Packet Tracer Labs http://www.lammle.com/discussion/showthread.php?t=6212&goto=newpost Wed, 08 May 2013 19:51:17 GMT Greetings,

I hope this makes sense. Or is it easier to think of it as one device and go down or up the layers and just commit to memory the processes at each layer and forget how and when it communicates to another device and how that then goes thru the layers again?

This question may be slightly outside the bounds of this chapter but as I was reading I was thinking about this and I am trying to understand switching and L2 traffic better so I figured I would throw this out there.

I have 2 NICs on my machine, one for a wired network and one for a wireless network, and both pull IPs from the same network, so they live on the same VLAN. Of course they have different MAC addresses.

When connecting with the wired NIC the switch will learn the hosts source MAC and add it to the forward/filter table.

Let's say I'm trying to SSH, ping, whatever, to another machine on that same wired network. During that ping or session I move from the wired connection to wireless. The wireless NIC will then ARP and the source MAC added to the switch forward/filter table. The switch and the entire layer 2 network should see this as a completely different computer and session right? Meaning that the original wired session would timeout and eventually the wired NICs MAC entry into the switch would time out correct? I'd have to re-initiate the ssh session or ping because there isn't any way the switch would know they are from the same machine, correct?

I hope this questions makes sense. ]]> Chapter 2: Ethernet and Data Encapsulation dae26 http://www.lammle.com/discussion/showthread.php?t=6207 boot system tftp? http://www.lammle.com/discussion/showthread.php?t=6206&goto=newpost Sun, 28 Apr 2013 23:20:08 GMT I was just playing with packet tracer, which would seem to allow a person to boot (or copy into RAM) an IOS image directly from a tftp server at... I was just playing with packet tracer, which would seem to allow a person to boot (or copy into RAM) an IOS image directly from a tftp server at boot-time.

I know PT will allow you to copy an IOS image using 'copy tftp flash'. That works fine; however, I can't make the above work. No matter how I phrase it (either using the instructions on page 289) or "(config)> boot system tftp://...", when I do show run-, I get "boot system flash tftp..."

So I'm assuming I'm missing something, because it seems the 2620 router (sim) wants to force me to use a flash filename, not a file on the tftp server.

I read somewhere else (tech republic) that to enable this on a real router, you have to modify the config register. Well, 0x010F doesn't work, but this article did say the registers on various routers may be slightly different, and to consult your router manual.

Well, I have no router at home, unless you count a netgear...I suppose I could browse Cisco's website for an operations manual, but...

Anybody else messed with this?
