Do the topics covered in CCDP _really_ help in the R/S lab? To be more specific... If someone already has CCNP, has passed the written, and is fairly comfortable with the devices on the lab (and others), then would it be better to study CCDP specific issues, or is it more 'time effective' to study BGP, DLSW+, etc.? I definitely agree that going for CCNP first is 'time effective' for starting anew, and I'm not 'trolling', but I would like your, and others', opinion on this issue. > Whatever you decide, best of luck with your studies and exams. > > Regards > > Jon CCIE RS > Nottingham UK. > > > > ""sisco"" wrote in message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Hi All! > > I just passed a ccna exam and i'm just confused if i'm going to > > take CCNP or jump into CCIE exam. > > > > Need ur opinion. > > > > thnks!

Re: wrong numberof hosts need help with CIDR!!!!!!! [7:49946]

Half will be taken by the 400 host subnet, for a /23. The 200 host subnet needs a /24 subnet, and the 2 50 host subnets will each need a /26. In addition, at least three 2 host subnets will be needed for the inter-router links (assuming a tree). So, you might start with the big pieces first, to get: 400192.168.24.0 /23 (this uses all of 24.x and 25.x) 200192.168.26.0 /24 (uses all of 26.x) 50 192.168.27.0 /26 (1/4 of 27.x) 50 192.168.27.64 /26 (1/4 of 27.x) Then you may want to start at the end and work backwords for the router links. This may leave a larger chunk, or so, for future use. 2 192.168.27.252 /30 2 192.168.27.248 /30 2 192.168.27.244 /30 Note: In many cases it is best to take the larger chunks out of the middle and then work outword for the smaller subnets. In this example that wasn't practical as the largest piece had to completely take up the first, or last, half of the available range.

All of the computers (>800), to include servers, are NT 4.0 and all run NetBIOS over TCP/IP, only. The network is completely flat, but everything is at least 100Mb FD. Everything is working fine. As others have said, the traffic really needs to be analyzed and performance evaluated to determine what is 'too much'. I've spent some time with sniffers and MRTG to find "bandwidth hogs", actually with more emphasis on multicast/broadcast hogs. The browser service has been disabled on all workstations (can cause huge spikes during browser elections), WINS has been installed, all unnecessary protocols have been removed, etc. The average non-unicast rate is about 15 packets-per-second, which is about 1% of 1% of the available bandwidth. Processor utilization on a 400MHz machine doesn't rise above 1% even during non-unicasts going over 100 per second. One of the reasons for the low CPU hit is because most of the non-unicast packets aren't for the NT boxes and the NIC cards don't even let them in. Packets such as BPDU's don't usually effect a computer. Now here's the amazing part (at least I think so). When I got interviewed for the job, my boss (he is now) showed me the network diagram. At the time EVERY computer was running TCP/IP, IPX (to include CSNW) and NetBEUI. Some servers were even running DLC as well. There was only switch which split the backbone for all of the workstations (at the time it was >500) into only 12 10Mb collision domains. Yes, collision domains, not broadcast domains. All of the closet boxes were 10Mb hubs. I looked up at him and said, "This actually works?" I think that is one of the reasons I got the job, especially since my predecessor left a couple of months before. Anyway, what is amazing is that even that scenario 'functioned' but it definitely needed 'tuning'. Once again, I can't empasize enough that you have to know how busy your network is, identify what isn't needed, remove what you can, tweak what's left (if possible ), etc. It is unfortunate that none of the popular certifications emphasise these skills, which data plumbers really should have. As Confucious said; "One must not only know how to configure an interface, but also know what goes through that interface." OK, he didn't really say that, but maybe he should have. ; ) HTH, Clay Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=49844&t=49704 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
