Re: (OT) Firewall!!!!
I think another important thing to keep in mind is maintenance cost. There is a lot of other stuff going on in a Solaris or WinNT box running Checkpoint, that usually requires basic systems maintenance from time to time. With a hardware firewall like PIX or Netscreen, they're designed to firewall and not require maintenance, and do it fast. They'll also reboot in the event of a crash about 10 times faster then a Checkpoint server, and handle higher traffic loads much more gracefully. So, in my opinion, hardware based firewalls are going to be much less cost in terms of initial investment and ongoing maintenance. hope this helps ;) david > > > -Message d'origine- > > De: ElephantChild [SMTP:[EMAIL PROTECTED]] > > Date: mardi 23 mai 2000 11:55 > > À:Achal Kataria > > Cc: [EMAIL PROTECTED] > > Objet:Re: (OT) Firewall > > > > On Tue, 23 May 2000, Achal Kataria wrote: > > > > > Just wanted to know one thing , which one is better PIX or > > > Checkpoint Firewall 1 and why?? > > ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

you'll do it manually just like any network management tools would do it. Take a timed snapshot from the interface counters (show interface) to figure out bytes/sec. then you can divide that by the max bytes/sec to get a percentage.

One easy way if you have expect installed is to run 'autoexpect', telnet to the router, run one command, then exit. After that, exit autoexpect, and modify the name of the command you ran with $argv. Then to run any command on that one router, you'd just run ./script.exp 'some cisco IOS command here' another way is to use an old livingston C utility called 'pmwho' still available on their ftp site at ftp://ftp.livingston.com/pub/le/contrib or something very similar to that. very strange that I've posted 6 answers now to the same two questions.

Re: extreme and cisco
yes, we had a couple catalysts, along with lots of fore and extreme switches at the place I was just working. In our environment, it seemed the Cisco ethernet interfaces worked fine, as long as auto-negotiation wasn't taking place. On both our router and catalyst 2924, the fast ethernet interfaces would usually auto-negotiate to 100Mb/half duplex when connecting to the fore's or extremes. Setting both sides manually to 100Mb/full worked great.

Re: Cisco and Unix
well, it depends on the employers. A lot of large enterprise employers won't look at linux yet because it doesn't have certain reliability features, and it lacks a long history in the market to prove itself. But, that's changing quickly because of all the press linux has received in the past several years including large amounts of support from Netscape, Sun, HP, IBM, and many others. And in my opinion, after doing unix admin for several years, I had no problem moving into solaris/sunos/irix/hp/bsd administration after knowing linux really well. It does, after all, include a mix of features from BSD/SYSv-ish tools. Just read the red unix admin bible by Evi Nemeth and friends and you'll get a good feel for the differences. Sorry for the topic digression, this is a cisco only list after all. But, it's been noted in several messages lately that obviously a good working knowledge of an operating system is necessary to really function well in a high level position. It is a piece of the picture, and knowing capabilities of various operating systems is quite important. It's like knowing all seven layers of OSI. How many CCNP/CCIE's out there understand the frame format's for DS-1, or SONET, or what B8ZS and ESF actually do? The OS implements all seven layers. Most network engineers work primarily with layers 2-4. If you understand the protocols outside these layers well it makes troubleshooting and understanding networks magnitudes easier. Back to your original question. Go get a free ($20 for the media) copy of solaris x86 from sun's web site, play around, and then focus on what you can do in linux (like sendmail, INN, BIND, etc) in your resume. And by the way, if I remember correctly from a recent linux journal article, Cisco's entire printing system is run off linux servers, with slightly modified code.

Re: Value of Cisco certifications
I think this issue can be taken in a much more practical sense. It's quite obvious that a very large majority of the people on this list already work in the technology field, some of which have contacts inside Cisco. If anyone from Cisco is monitoring this list, or gets copies of emails that may violate NDA's, it would not be difficult for them to contact one of the individuals cc'd on the message, or contact the list owner and track down received: headers from the originating poster. If you have concerns about NDA violation in what you're posting and don't want to have your certifications revoked for any reason, then you probably shouldn't post your question in this public forum. David - -Original Message- From: TyRhon144000 To: [EMAIL PROTECTED] Sent: 5/30/00 2:47 PM Subject: Value of Cisco certifications Is there any way Cisco can make their certifications challenging enough, that they can give a realistic estimate of a person's skills? I really don't believe that there is such a thing as paper-certification, everyone's certification comes on paper and everyone has to do some amount of study to get certified. Yet, as a CCNA myself, I would like for all of Cisco certifications to reflect real world knowledge. I applaud Cisco for making the CCIE as challenging as it is. I am also happy that just about every CCIE lives up to the NDA. If only those who have obtained other certifications from Cisco lives up to the NDA, then maybe some of their other certifications will not lose credibility.

Re: RAID question
well, i do think this is a bit off-topic for a Cisco list, but here goes. All major NOS support RAID 1-5, and probably 0+1, although I'm not sure about that one Most hardware RAID devices do the same. I'd wager at least 95% of installations use RAID 0, 0+1, or 5 depending on speed and cost requirements, and a few applications use 3 and 4. I've never seen raid 2 in use. Search for 'raid' on www.whatis.com for a decent description of all the RAID types, or read "The RAID Handbook" for everything you've ever wanted to know.

Re: Sniffing on switched networks
you can define static arps, but I can't think of anything that would be more difficult to manage. arp spoof attacks are fairly rare in practice (that I've seen at least -- but they're fairly new as well). The most important thing you can do is make sure your local networks are safe from attack and safe from people exploiting root access. Of course, since it's near impossible to protect yourself 100%, some people are working on AntiSniff tools (antisniff being one of them) to detect things like this. I haven't checked up on all their capabilities, but there was a recent post to BUGTRAQ about them. Search the archives at www.geek-girl.com.

Re: Checkpoint firewall
while on the topic of security, I almost see it as a necessity of any
good administrator (depending on your function(s)) to be a part of the
BUGTRAQ security mailing list. This has been an excellent resource for
many years, that eventually most exploits and security problems make it
to, whether Unix, NT, application, or network device related. There
have been many exploits on many firewalls, router OS's (a few on IOS
too!), switches, talks about bypassing VLAN's over trunks, ARP spoofing
code and discussions, and many other topics related to postings I've
seen on this list. I have learned quite a lot by just subscribing to
this list for the past 5 years.
BUGTRAQ is archived at www.geek-girl.com (among others I'm sure) for
those interested.

Re: Checkpoint firewall
What is even more fun is trying to send a packet requiring fragmentation
from Linux through a firewall! A small snippet in the kernel source
shows that linux will fragment a packet and send the LAST fragment
first, for various reasons that I don't completely understand. This
means that the first fragment of a packet from a linux host will have no
layer 4 info! What is a firewall supposed to do with that other then
hold it in memory, and use some kind of timers and DoS checking code in
the firmware? I only dealt with this on the Netscreens, and they
currently pass the fragments through for this reason if I remember
correctly. This isn't perfect, but not too bad, because the host can
most likely handle this better then a firewall handling thousands of
connections for all hosts with a limited memory capacity.

Re: Microsoft 'Routers'
FYI, unix has also had routing capabilities inherent in the operating system, as well as software for BGP, OSPF, RIP and friends in free software like routed/gated since the beginning of the Internet. But, would I ever use any unix box for a router? Not unless it was five years ago, it was linux, and I was starting up an ISP with pocket change. That was the trend while companies were out there providing descent T-1/ISDN/PRI/Frame Relay cards and drivers for Linux x86 machines. The good thing about this setup, is that Linux can route a full T-1 without any trouble using aging 486 hardware (ie: very very dirt cheap router... $50?). But what's that , you want to route a DS-3? Unlikely. I don't know anyone that makes DS-3/HSSI cards for PCs. Anyone want to jump in on that? But, I've never trusted Windows NT/98 etc to do any routing, unless I wanted it to crash all the time -- and no I'm really not wanting to start a discussion about which is better or anything. I'd be interested to see how much microsoft has cleaned it up in 2000. I really have a lot of hope for this OS in terms of functions (ie: active directory) and hopefully a newfound stability. In general any PC is not built for high speed routing. There will be hardware architecture limitations to it's performance. Also, since the operating systems are so bloated (compared to something streamlined for routing like IOS), and running tons of applications at the same time -- unless you have a dedicated box -- a server will have a lot of other things to do other then route packets. If you have no needs for real performance, perhaps you could use a windows platform as a router, but considering the resource needs of Windows in terms of hardware, you'd be better off buying a real router instead. There is an interesting Linux mini-distribution out there called LRP, or The Linux Router Project. It's a linux OS that fits onto a floppy (or it did at least) and has full capabilities for routing and other things like firewalling I'd assume. I haven't looked at it for a long time. It's at http://www.linuxrouter.org although the server doesn't appear to be accepting connections right now. hmmm, I hope it's not running on a LRP distribution hahaha.

Re: What came first?
nope, FECN and BECN are bits strictly in the frame relay header. ICMP will have nothing to do with this. These bits will only be set by frame relay switches in the cloud that don't know a thing about layer 3, IP, or ICMP. When they can't process frames fast enough, they'll set these bits to ease congestion on their hardware (and buffers, etc.). It's then up to the endpoint stations' higher layer protocols to initiate retransmission, as they will never see the discarded frames. I'm actually not sure what source-quench does myself, and I want to leave work NOW, so I'm not going to look it up ;) David Dale Cantrell wrote: > > Evening all, > I'm reading about Frame Relay on Protocols.com and a question arises. > When the network becomes congested to the point that it cannot process > new data transmissions, it begins to start discarding frames.

But five years ago the only choice out there for this kind of setup was linux 1.2 (and probably FreeBSD, please excuse my lack of knowledge of that platform) and that's what many mom and pop ISPs used for a basic T-1 router using things like the ETINC cards, and dialin service, using the Cyclades and RocketPort cards and USR modems when they were the best around.

I agree with the necessity to maintain connection state in any type of real firewall. And I'll go ahead and point out that Linux 2.4 has added a multi-threaded networking stack and updated firewalling code, although I haven't checked its capabilities yet. The IP filter kernel module -- that I assume is still the code which does the firewalling you mention above in FreeBSD -- has been ported to linux 2.0, and I'm sure 2.2/2.4 is done or well underway although I didn't look that deep into it. I've long heard the heralds from unix people about the rock solid everything of FreeBSD's TCP/IP stack. I've just don't have extensive experience with it. This thread should probably cease before it drones into a unix geek session.

Re: Firewalls
well, simply blocking traffic from outdoors and using NAT is usually OK for a SOHO or regular user, but in general access lists ARE NOT A FIREWALL. They don't keep status of connections and do any realtime inspection of traffic looking for more then just IP/TCP/UDP information. A stateful firewall keeps an active table of all connections and can do a lot more then just deny traffic on basic things in the layer 3/4 header. If you really want to protect a network don't just use access lists. In larger environments, one of the big factors to address is performance. If you're sitting behind a T-1 with 40 to 50 average users and a server or two, this may not be a big deal. Any decent software based firewall or small hardware-based solution should be fine. But if you're sitting behind a network with hundreds of users, hundreds of servers, and pushing 50+ Mb/s of traffic out multiple DS-3's, you better A. Make sure you segment your network and use multiple firewalls. B. Use a fast hardware based solution. Some of the bigger firewall platforms out there are Checkpoint's Firewall-1, Cisco PIX, and my current favorite, Netscreen. I'm not sure about netscreen's site right now, but Cisco and Checkpoint should have some basic firewall/security documentation out there about firewalls. There are plenty of good books on firewalls out there as well as things on the Internet, but I haven't searched.

Re: Firewalls
You'll probably want to look up performance stats with Cisco and Checkpoint directly, although I would doubt that Checkpoint is faster. Can someone else with more experience on PIX hardware jump in with more information? You also have to look at the cost perspective. Ok, maybe Checkpoint running on an E450 or an E3000 will be as fast as much less hardware/cost in a PIX solution. But, do you have the extra rack space to lug one of those Sun boxes in? Do you have a hired unix admin to take care of the box when it goes down, or needs general maintenance/upgrades? Sun reps can be expensive. In general, hardware based firewalls are always going to be faster. I've worked a lot with the netscreen 100 devices that are mostly hardware based, cost about $10,000 and use 100Mb ethernet ports on all sides. They perform very well under a wide variety of traffic loads, although I've never pushed more then 70Mb/s through it. Using a SmartBit to max it out isn't always the most realistic of scenarios either. Netscreen claims that their hardware adds very little (microseconds) latency, but again, this is all in their labs using only SmartBits. I haven't measured realistic latency myself. Ok enough firewall plugs.. I'd really suggest going to the NetworkWorld trade journal site http://www.networkworld.com and searching for firewalls in their archives. They do routine performance evals of every major platform out there.

Re: Diff between point to point T1 and T1 with framerelay
sure.. PPP (point-to-point protocol) and Frame relay are both different layer two protocols that run on top of the T-1 service. PPP over T-1 is the same PPP the is commonly used for modems when dialing up to an ISP. It's based on the HDLC protocol. Frame relay has an addressing scheme separate from IP that makes it a shared protocol that can be switched throughout a telco providers switch network. It uses the concept of a DLCI (Dynamic Link Channel Identifier) and of SVCs and PVCs to implement a point-to-point or point-to-multipoint scheme connecting many sites over a single physical circuit. Essentially, the provider can say ok, here's a PVC (Permanent virtual circuit) at DLCI 16 that points to company B, and here's another that points to Company C on dlci 17. you set these up on your side, and then the provider gives the other companies their own dlci numbers that correspond to that circuit connection. SVCs do the same thing but on an as-needed basis. many providers don't support these. frame relay also provides LMI (local mgmt. interface) to list DLCI numbers and assure connectivity (among other things) to a FRAD (frame relay access device). it's important point to note that because of frame relay's features and the fact that it is switched (PPP is mapped directly from point A to point B by the provider), mean that overhead is incurred and a portion of the total circuit bandwidth will be used by the protocol. So, a T-1 won't be able to run at a full T-1 speed over frame relay, and the network won't provide you assurance of that unless you give them lots of money. This gets into congestion control (FECN and BECN) and the concept of CIR. Many of these terms (HDLC, frame relay, PPP, T-1, etc.) are fairly well definied with links to further explanations at http://www.whatis.com. i love network acronym speak. it makes me feel like a doctor. hope this helps, david John Zaggat wrote: > > Can some clearly explain the difference, I have > checked the Archives and not found a good explanation. > Also if you have some sample configs, that would be a > great help to me. > Thank you. > > = > JZ > [EMAIL PROTECTED] > > __ > Do You Yahoo!? > Yahoo!

SNMP set - tool?

I actually only have access to Win NT :( Can anyone recommend a freeware or similar application that will allow me to perform SNMP queries?

FW: catalyst 1900 problem
A question from a couple of weeks ago. I had the same problem with the modem like display. Working through BTAC we have corrected the problem. When using the standard terminal clips and roll over cable connected to the console port of the 1900 switch you can get into the diagnostics mode (hold down the mode button while power cycling), but not into the configuration main menu. You will need a null modem cable to connect properly to the console port. Once we plugged in a null modem cable the main menu popped up and I was able to do the configuration.

Re: SNMP set - tool?
Thanks a lot for that - It does exactly what I was after. For anyone interested, here is a brief overview of what I had to do to get it working: After installing the application, I grabbed all of the Cisco MIBs (http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml) and threw them in the MIBs directory of GetIF. I set up the router in the parameters tab (IP, SNMP community strings), then entered the command in the bottom of the MBrowser tab: .1.3.6.1.4.1.9.2.1.55.$.$.$.$, s (string), then the name of the file to write to on the tftp server.

FW: EMUTEL LITE setup
The spids are most likely configured in the emutel lite already since they come from the factory with a default setting depending upon which version of the emutel lite you have. The default ISDN switch is a basic-ni1 if I remember correctly. Obviously, if you got an emutel lite with a European siwtch type, then you won't have any spids to worry about. I thought it was a breeze to set up the emutel lite because there was essentially no configuration. If you don't have the manual, download it from the emutel web site to get what the default spids are. You may not need NT1s depending upon whether your 2503s have U interfaces or S/T interfaces. I am assuming you must have S/T since you are using the NT1s.

RE: SNMP Agent on Router
The mib database is installed on the SNMP manager (the host), as part of the snmp application running on that system. The router sends numeric strings (traps) to the listening SNMP manager indicating events have happened like a power supply failure or a wan link down. When the SNMP manager receives one of these numeric strings it looks through the mib database and resolves the meaning of the trap. If the trap is not in the mib then the manager won't be able to resolve the trap and will usually report just the numbers in an snmp log or similar. If the trap is in the mib, it will report something a little more meaningful. Here's a trap for an ISDN link going inactive SNMP 10.10.10.254 Trap(linkDown) ifIndex.5=5 ifDescr.5=BRI1:1 ifType.5=23 cisco.2.2.1.1.20.5=down Here's a trap for a power supply being turned off on a Catalyst 6509, where the trap is not in the mib database. SNMP 10.10.12.12 Trap(cisco.5-6.5) cisco.5.1.2.13.0=1 cisco.5.1.2.11.0=2 cisco.5.1.2.12.0=1 cisco.5.1.2.9.0=2 cisco.5.1.2.10.0=0 cisco.5.1.3.1.1.10.1=2 cisco.5.1.3.1.1.11.1=0 cisco.5.1.2.4.0=2 cisco.5.1.2.5.0=0 cisco.5.1.2.7.0=4 cisco.5.1.2.8.0=32 See how it just says cisco followed by some numbers. The application was able to resolve the first part of the trap to the private enterprise family of traps for Cisco but it didn't know what the rest of the numbers mean. The solution is to get the mib for Catalyst 6509 and import it into the existing mib for the SNMP application.

OSPF design question re: location of Area Border Router
Hi, I am preparing to bring up a new site in an ospf network. The new site will be a training facility connected back to the main office by a t1. Currently we use OSPF and have everything in area 0, around 100 routers. I want to make this new site a different area and to make the new area a Totally Stubby Area. We have two 7513 routers at the main office that handle all the wan traffic, the new remote office would connect to one of these. The remote training office will have a 4500. One of my coworkers suggested that the 7513 at the main office should be the Area Border Router, because we should keep area 0 from being spread out over a bunch of wan links. I had it in mind that the remote 4500 should be the ABR. I don't have a strong reason for thinking that way. The cpu of the 7513 runs between 20-30 % utilization according to snmp info. Are there any rules of thumb regarding this? I looked through the Cisco OSPF network design book and can see some examples that support having the ABR at the main office. Is that the accepted practice? Are there any gotcha's to look out for?

The bulk of our traffic between branches is TCP/IP and we tend to terminate between 7 and 10 PVCs on a single T-1. We also have an additional PVC to each branch that is solely for SNA traffic, which is very low volume, and we're using static routing here.

icmp weirdness
Hey folks, I've got an issue at work I'd like to run by you. I sent a request to cisco's forum but have yet to hear an answer from anyone. We have a Cisco 2610 router in Ireland. This router has 1 Ethernet connected to a local segment and s0 point-to-point frame relay going to chicago, Ill (sub interface). Heres the details on the Ireland router: Ethernet segment: e0's primary address is 132.158.132.252/24 (some hosts refuse to change addresses). e0's secondary is 10.43.0.1/16. Serial 0/0.1 is 10.126.43.2/24. All advertised by Eigrp. Chicago's router is: Ethernet segment is varibly subnetted 10.4.0.0/16. Serial 0/0.13 is 10.126.43.1/24. Once again, Eigrp is the routing protocol. There is a host on Ireland's lan with address 10.43.3.230/16. If I log into Ireland's router and issue ping 10.43.3.230, nothing happens. It just times out. If I log into Chicago's router and ping the same host, it replies fine. If I ping it from a host behind Chicago's router, it replies as well. If another host on 10.43.0.0/16 pings that host it replies fine. I can ping any of 3.230's neighbors no problem. Its just that Ireland's router wont ping it at all. show ip route verifies a route as directly connected. Has anyone heard of this? A bug? I can't verify all the way down because I don't have physical access to Ireland's lan (thank god) to put a sniffer up. We are trying to use this host for a second default route to a vpn box incase the frame relay ever fails (and it does... often). Sorry to drag this on. Thanks in advance.

It should be a fun project. If things go well, there might be a couple of other sites that would be setup similarly on this same 7513 router. More than anything, I'm trying to explore some other features OSPF can offer instead of making everything part of one big area 0, which has worked fine so far. Dave H -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 28, 2001 4:54 PM To: [EMAIL PROTECTED] Subject: OSPF design question re: location of Area Border Router John, You could equally well have the 7513 with one interface in area 1 and the rest in area 0, and the 4500 with all interfaces in area 1, in which case the 7513 is the ABR. David, Am I correct in thinking that the only router at the remote site is the 4500? Or is there more 'behind it'? Because if the 4500 is the only router, you're not gaining much by making the 4500 the ABR. Area 0 will still include all the routers in your network, and the 4500 will still have all the area 0 information. You can summarise your remote site routes into area 0, but that's about it. Are you planning on extending this idea and having lots of other areas set up in the same way? Generally regarded as not a good idea to have 'too many' areas defined on one router - the guidelines I saw last (quite a while ago) suggested a maximum of three areas per router but even at the time that was a very vague rule of thumb - they also suggested a maximum of about 60 routers in an area which you are obviously exceeding, presumably without problems. Running area 0 over WAN links is not necessarily a terrible thing to do - if your network is stable, OSPF doesn't spew out lots of traffic. Making the 7513 the ABR is probably your best bet - it sounds like your 7513 can cope with it (check your memory usage as well, though).

If you have a 7513 in area 0 connected to a 4500 in area 1, for instance, then the 4500 will have one interface in area0 and the rest presumably in area 1. By definition, that makes the 4500 an ABR, doesn't it? I don't see how you have any choice in this matter at all, but since I've never actually configured OSPF perhaps someone will enlighten me. >>> "Hennen, David" <[EMAIL PROTECTED]> 2/28/01 9:32:59 AM >>> Hi, I am preparing to bring up a new site in an ospf network. The new site will be a training facility connected back to the main office by a t1. Currently we use OSPF and have everything in area 0, around 100 routers. I want to make this new site a different area and to make the new area a Totally Stubby Area. We have two 7513 routers at the main office that handle all the wan traffic, the new remote office would connect to one of these. The remote training office will have a 4500. One of my coworkers suggested that the 7513 at the main office should be the Area Border Router, because we should keep area 0 from being spread out over a bunch of wan links. I had it in mind that the remote 4500 should be the ABR. I don't have a strong reason for thinking that way. The cpu of the 7513 runs between 20-30 % utilization according to snmp info. Are there any rules of thumb regarding this? I looked through the Cisco OSPF network design book and can see some examples that support having the ABR at the main office. Is that the accepted practice? Are there any gotcha's to look out for?

snmp monitoring PBX equipment that doesn't have a network connection
Hi, I'm looking into monitoring of some "mission critical" communications/network equipment. Some of the equipment doesn't have a network interface, like a PBX or some brands of UPS for instance. Focusing on PBX's, does anyone have experience in methods to remotely monitor this type of equipment, using snmp or some other method. I recall hearing about using the dry contact inteface cards from APC to do something similar. A question that comes to mind is whether, using APC's triple expansion chassis, can I have an Environment Monitoring Card and an SNMP card both running and configured so a break on the contacts on the Env. card will trigger an snmp trap from the snmp card? War stories about similar projects would be appreciated.

Re: icmp weirdness
Hey, thanks for the help. In the frame relay network we have, hops are transparent kind of. Only the CPE is visable. I had established that the problem was occuring at the last router's ethernet interface. When I trace the routes out it just gets to that router and times out. What Erick B. pointed out was due to the fact that the primary address on e0 was not the same network that the host in question was on. This turns out to be the case. If I do an extended ping and source the packets from the secondary address, the machine responds without haste. I've requested that the administrator of the hosts over there build a static route to the foriegn network address to help out although I don't suspect it will help alot from an analytical point of view. :) Thanks for all the help! - Sorry for the delay in replies.

The two multicast addresses used in OSPF that I know of are 224.0.0.5 and 224.0.0.6. From my understanding, in a broadcast network, all ospf routers send link info to the DR/BDR with the address of 224.0.0.6. The DR will then send all the data back to the DROTHER routers using the address of 224.0.0.5. Is this correct? I previously thought that the DR sent the data back using the address of 224.0.0.6, but this wouldn't work because the DROTHER routers don't listen to that address. Is this also correct?

Re: Serial intermittant flapping
You're gonna love this we've been trying to pin it on the carrier for a while latest rumour is that the radio bearer (rather transmitted waves) at the central site gets 'radio fade' during high tides the thing you don't see when you're not at site hence the intermittant nature... now if I can just correlate the tides with the flapping David >>> "Brian" <[EMAIL PROTECTED]> 03/15 7:36 am >>> Looked at serial interface usage, I mean is it dropping during periods of peak utilization?

OSPF
Hey all, I've been reading into BSCN here lately with Cisco press books. In the book there is a fairly detailed discussion of OSPF. I'm not in the least opposed to learning it. One thing I would like to understand is why an organization would use it. Is this used in ISP's? What are the advantages of it over say, EIGRP? I always see it compared to RIPv1 but I find it silly for advanced routing protocols to be compared with ripV1. Please forgive me if this is shortsighted of me.

RE: differences between the 2505 and 2524
the 2505 has a built in 8 port 10BaseT ethernet hub and 2 serial ports to which you have to attach external connectivity devices like csu/dsu. The 2524 has one on board 10mb ethernet port (10BaseT I think) and three modular slots, one of which is dedicated to ISDN BRI. The other two can have various modules installed for 56K to frac/full T1 connections and can include the csu/dsu internally with the appropriate module. hope this helps, dave h -Original Message- From: Aidan Manning [mailto:[EMAIL PROTECTED]] Sent: Friday, March 16, 2001 5:27 AM To: [EMAIL PROTECTED] Subject: differences between the 2505 and 2524 Can anybody tell me the differences between the 2505 and 2524 as I'm setting up a test network for webhosting.
