L3 switch that support Gigabit Ethernet
Anyway, recommandation? Cisco 7500 router and Catalyst 5000/6000 series seems not suitable, as it as very slow backplane and $$/gigabit channel are very expensive. i think it's because it is not designed for gigabit switiching Anyway, I've checked Cat. 4000, it seems oko. But, are there any other suggestions?

Re: Advice for a Newbie setting up a lab
This one's easy to answer: dump as much money as possible on routers, token ring equipment, beer, and maybe, if you're married, pay your wife off. Nah, but really, I would buy a few 2500 series, mix ethernet and token ring, if you have the cash, buy as 2509 and 2511 to use as an terminal server, makes it easier. You can get away with buying an old AGS+ to hook a bunch of serial connectios up to, or use as a frame-relay switch, but they wont run the newer IOS, I think they run somewhere in the 10.x's, enterprise though if I remember. A 4000 with a few serial modules makes for a good big daddy router, maybe buy a catalyst switch with the same IOS style that the cat5k's have, these are hell expensive. Anyway, the real lab has about 6 routers and 1 cat5k, so buy a 4000, some kind of switch, and fill the rest with 2500's. Also note that Oz, a member of this list, has some deals posted, I'd check them at, he has kits and what not, good resource, we all love Oz. And don't try to quit smoking, and if you can, have some sex, have fun, Cisco wants you too, they party.

RE: OSPF !!!
Tim - What do you think about just entering the shutdown command on the interface that the current DR is located? This of course will depend upon your network and may not be an appropriate idea. Once the DR is down, the BDR will be promoted and a new election will take place for the new BDR slot. (This of course assumes that you want the current BDR elected to DR.) Once the new election has taken place, you can issue the no shutdown command on the old DR.

OT: Need Documentation Database NOT MGMT software
I know some of you mentioned HP OpenView, CiscoWorks, WhatsUpGold however, I am not looking at visual network management tools. I am seeking a database template or software that will allow me to lookup PVCs, contact names/numbers, circuit info, billing info for the site, T1 channelization, router serial #s, router maintenance contracts, multiple IP addresses on multiple interfaces, PPP and Frame relay circuits. If the software also had some change management functionality that would be good to as I often upgrade circuits, add PVCs, send new routers to new sites. Right now my documentation is in Word, Excel, and Notes. I want to use one piece of software to the job. I'm not really looking for something like Visio Enterprise. I just need to put all of this info in a database (Notes, Access, 3rd-party product) so that I can keep track of my network and the changes. This will allow me to DO THE DOCUMENTATION IN VISIO! I've got about 100 sites with more coming. How do you guys do this? Do you even keep track of everything in a relational database? Do you only rely on Visio Enterprise? Or do you even care about documentation? :( Please help - new WAN guy needs your help! Thanks in advance!

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.

I have tried different switch-types, and with spid and without. Last night I say something about CAPI, I take it that my 2503 does not support CAPI, the question is, Can I get my 2503 to dial my ISP, or is my router just a paperweight with a loud cooling fan?

Re: OSPF Process ID
The process id in OSPF is basically so you can run more than a single OSPF instance on a given router(s). At first it would seem unclear as to why you would want to even run more than one OSPF instance, but think about this: You work for company A, you have a large multiple area OSPF network, your healthy routers slap the hello packets out, flood LSA's, all is good. Then Johnny Q. Corporate, your CEO, decides to buy Company B to narrow competition down, Company B also has a large multi area OSPF network, but their timers are different, your routers can't deal with these "invalid" Hello packets coming in, so to merge the two networks together, you could make the router(s) hooking Company A with B together run one OSPF instance for Company A, and one for B. This saves you a hell amount of time on reconfiguring routers, provided you can redistribute effectively. Isn't this what an AS does? Not by nature, althought it does end up being one use of an AS, and especially in this situation. AS's also discuss route policy, it's the 90's. Or maybe you have two networks that don't connect together, but they share one router. Again, it's best to use seperate OSPF id's for each, than try to filter and the like.

Re: ISDN setup
Hmm, groupstudy seems to be eating messages again - sorry if this appears twice. JMcL ** One thing to watch out for is that a frame relay PVC can be down without the router interface being down. Then the 'backup int' command doesn't kick in, because the router doesn't realise that the frame relay interface has gone walkabout. If this is a problem, you can use floating static routes (static route(s) with the administrative distance set to something higher than the routing protocol you use on your FR link) to direct your traffic to the ISDN interface. Under normal circumstances, with the frame relay link up, routes to R2 will be sourced from RIP or OSPF or whatever routing protocol you use over the frame relay link (possibly even a static route). If the frame relay PVC dies, that route will disappear, and your routing process will pick up the floating static route instead and send your traffic over the ISDN. Just make sure your interesting traffic etc is set up for what you want. Floating static routes aren't quite as simple as the 'backup int' command but they're a lot more flexible.

Here's the link: http://www.vstream.com/login/CISCOCP/CISCOCP_login.vhtm?PREFS=CISCOCP You need a CCNA,CCDA and a sales expert to become a reseller (you do not need a revenue commitment!). I hope this helps and by the way, there is other training that I have com across, like the FREE CID course, which needs to be augmented by the book and the Boson tests. You'll ace it then (hell, you only need a 65% to pass the damn thing, not really a monumental task).

Re: Frame relay question
Here's my opinion; An NNI (Network to Network Interface ) is being used to interconnect 2 different frame-relay networks on a PVC basis. This way a dlci on one network can be pointed to a dlci on another network ( with the NNI in between the 2 telco's ). You normally thus don't need to configure it as an NNI, unless you need traffic to be transmitted from one frame provider to another...

Re: collision on cut-through switch
Hi, Priscilla, I think the best way to find this out is to just get yourself a network tester to connect between the transmitting host on port 1 and the CISCO box. ( like a FLUKE ) You will be able to see ( or not ) the JAMS on port 1. When you connect the host in that segment only and there's a jam during a collision on port 2 you know enough... In my humble opinion you are right, but that's male intuition ;-) Barry Priscilla Oppenheimer <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi Group Study, > > I got into a discussion with a knowledgeable Sniffer instructor recently. > When he teaches cut-through-switching theory, he warns his students that a > cut-through switch does not really isolate collision domains.

collision on cut-through switch
Hi Group Study, I got into a discussion with a knowledgeable Sniffer instructor recently. When he teaches cut-through-switching theory, he warns his students that a cut-through switch does not really isolate collision domains. Consider this example: * The switch is receiving a frame from port 1 destined for a station out port 2. * The switch recognizes the destination address and starts forwarding the frame to port 2 ASAP. * There is a collision on port 2. (It's a shared and/or half-duplex Ethernet.) According to the instructor, the Switch sends a jam signal back to port 1 to let the initial sender know that the frame experienced a collision. This allows the sender to retransmit. If you read some of the books on switching, you would think that this is true. The books make it sound like the frame is passing through the switch and disappearing out the destination port as soon as the destination address is recognized. I don't think the Sniffer instructor's conclusion is true, however. I believe that a Cisco cut-through switch buffers the frame and hence has the ability to retransmit. There is no requirement to send a jam to the original sender because port 2 in our example retransmits after sensing the collision. I believe that Cisco switches store frames, even when doing cut-through, whereas the instructor assumed that the frame has passed through and out the port and is no longer available for retransmission by the switch. Cisco positions cut-through as reducing delay, not reducing the need for buffering, so I'm contending that I'm right. Who do you think is right? Can you point me to any white papers that would prove who is right?

Hi guys, Passed the cvoice test on Friday. Not much of a high mark, but I'm glad it's over. I must say the test is one test to prepare for. I had over 15 fill-ins, as in almost made the ACRC test look like a joke (in my opinion). Nice one though, because of my EE background. Lots of sweet EE (Communications gist). So that makes me CCNP+Voice, CCDP plus a couple of some stuffs. Thanks to everybody on this group. I must say you have given me the required confidence to face this test. You are the "real" friends I've got as far as Networking is concerned. I wouldn't be able to mention anybody's name because this includes EVERYBODY. Many thanks to you all for keeping this list alive. It's just so rewarding listening to the "BIG" boys (& girls of course) yarn hardcore Cisco stuff.

Either that, or my paranoid sense is tingling (apologies to Spider Man). First: Get an UPS! Preferably one that you can lock. Take come hot glue, and glue the power cord into the router, and into the UPS (do so in such a way you can tell if the power cord was removed). Put a security tape (like the "do not cross this line" tape used by the cops) over the power switch on the router and on the UPS. (I find it hard to believe that you would have a multi-kilo dollar router that is not on at least 100 buck UPS). That will help detect him/her at the physical layer. I assume she/he gets in through the console port. Secure it, and require a password only you know. Put a modem on the AUX for yourself for OOB management. Implement a TACACS/RADIUS, and assign this person a username/password. Track the hell out of it: there are more ways to do this than to choke a cat. ACL! ACL! ACL! Use them! If this person is telneting, lock down your telnet sessions. And, of course, you have SNMP!I assume that you have some type of monitoring software? If so, monitor the router: whenever it goes down, you should be paged immediately, and have a phone in that room with teh router so that you can call this person and tell them to get out of there NOW.

Replace this with a physical path, usually C:\Program Files\Internet Explorer. This has worked every time I tried except once. Not sure what was different about that machine, but I didn't bother troubleshooting it too far... > > ""Bharat Suneja"" <[EMAIL PROTECTED]> wrote in message > 8ifomk$o82$[EMAIL PROTECTED]">news:8ifomk$o82$[EMAIL PROTECTED]... > > I think it sucks big time. why couldn't they make a better > documentation > > CD ?

The controller configuration sets up the basic parameters of the physical interface/CSU-DSU, and instantiates the serial interface. The serial interface doesn't exist until the controller is configured.

Router Rentals
Hi all, I can't find the message someone posted not too long ago. They were asking about a list of where you can rent routers online. This is a list I have gathered myself over time. http://labsonline.remote.net http://www.cciehq.com http://www.simrouter.com http://www.routeru.com http://www.mentorlabs.com http://www.virtualrack.com http://www.cciebootcamp.com http://www.fatkid.com http://www.solutionlabs.com http://www.rentarouter.net I am not aware of any others. All of these allow you to rent routers to the best of knowledge, some are busier than others (when you actually want to schedule some time). That is the one problem I encountered was trying to find some with available time not 4 months down the road but sooner. And most don't even post their availability schedules online. Some you email and get no replies, others are great at responding.

re: Difference between OSPF on NBMA Broadcast and Point-to-Multipoint?
Hey, Michael,
Here I go again... Chuck, correct if I say anything wrong!!!:) I am
quoting this from memory...
OSPF modifies its behavior based on what it defaults to on an interface.
For example, OSPF will default point to point over a point to point link
(i.e. HDLC), and will not elect a DR and the two routers on the link
will become neighbors. Hello's are multicasted between each router.
LSA's are unicasted.
You, as the human network engineer, can modify and tell OSPF how it
should behave. For example, if you had two routers connected via their
ethernet (a broadcast network) interface, you could tell OSPF that the
network was point to point; it would not elect a DR as it normally would
on a broadcast network.
When you tell OSPF that the network is Point to Multipoint, it will
treat the network as a collection of point to point links; one of the
routers will be the hub (it has connectivity to all other routers), all
other routers will be spokes. The spokes can talk to the hub and vice
versa, but not each other. Again, as on a point to point network, no DR
is elected, multicasting is supported by default.
When you tell OSPF that the network is nonbroadcast, you are telling it
that it can not multicast. Since it can not multicast its hello's, the
routers on the NBMA network will not become neighbors. You as the
engineer must execute the neighbor command, and tell the routers who
their neighbors are. A DR is elected on a nonbroadcast, and the
priority could become important, depending on the amount of meshing you
have.

Conversation: Difference between OSPF on NBMA Broadcast and
Point-to-Multipoint?
Subject: Difference between OSPF on NBMA Broadcast and
Point-to-Multipoint?
Could anyone clarify for me the difference between OSPF on NBMA
Broadcast
and Point-to-Multipoint? The configuration looks the same to me. I'm
using
the All-in-One CCIE Study Guide as reference, lab 37 or something. I
know
that with P-to-M, that no DR is elected and whatnot, but could you give
me
something more concrete? What is real world difference? When would you
ever
run an NBMA network as broadcast? To cut down on configuration?
Thanks.
Michael

re: Help me catch a Hacker
Nabil, I did not bother to backtrack your message, and I am giving you the benefit of the doubt; however, your message has a distinct smell of salmon about it. Either that, or my paranoid sense is tingling (apologies to Spider Man). First: Get an UPS! Preferably one that you can lock. Take come hot glue, and glue the power cord into the router, and into the UPS (do so in such a way you can tell if the power cord was removed). Put a security tape (like the "do not cross this line" tape used by the cops) over the power switch on the router and on the UPS. (I find it hard to believe that you would have a multi-kilo dollar router that is not on at least 100 buck UPS). That will help detect him/her at the physical layer. I assume she/he gets in through the console port. Secure it, and require a password only you know. Put a modem on the AUX for yourself for OOB management. Implement a TACACS/RADIUS, and assign this person a username/password. Track the hell out of it: there are more ways to do this than to choke a cat. ACL! ACL! ACL! Use them! If this person is telneting, lock down your telnet sessions. And, of course, you have SNMP!I assume that you have some type of monitoring software? If so, monitor the router: whenever it goes down, you should be paged immediately, and have a phone in that room with teh router so that you can call this person and tell them to get out of there NOW. You should have a second number to their boss, and tell him about this person. Then you should have a third number to the boss of the boss. Good luck catching your "hacker".
