Some Catalyst switches assign a global MAC address, some switches use a pool of addresses assigning one to each interface(You can assign one manually), and sometimes the MAC address can be a virtual MAC address when using HSRP on mulitiple internal route processors such as the MSM, RSM, RSFC, NFFC, NFFCII or the MSFC.

They are connected to the same port on the switch the switch does nothing since the two nodes are in the same collision domain they will see each others traffic. If B. They are in the same VLAN and reside on the same switch, the switch learns the location of each node attached by reading the first frame received and logging the source address and port of arrival in it's Content Addressable Memory(CAM) table. When the switch receives another frame it checks the CAM table and if it knows the port the destination node resides on it forwards the frame directly to that port. If it does not know the port, it broadcasts the frame to

RE: Switches !!!
Is it possible that Cisco's Layer 3 switching has evolved beyond the way things are done of the 5xxx platform. For example, my reading of the product description of the Catalyst 4908G-L3 switch provides this info: - The Catalyst 4908G-L3 provides a complete IP routing solution without sacrificing any of the services that are required to build a scalable network. The Catalyst 4908G-L3 is a feature-rich switch with full Cisco IOS implementation that allows network managers to continue to administer and manage their networks as they do today while scaling their backbone bandwidths to gigabit speeds. The Catalyst 4908G-L3 supports all the routing protocols that are used today in mid-sized networks. These protocols include: * Interior Gateway Routing Protocol (IGRP) * Enhanced IGRP (EIGRP) * Open Shortest Path First (OSPF) * Routing Information Protocol (RIP) Versions 1 and 2 * Static routes * Route redistribution Now if this guy is an OSPF router, and therefore contains a full table of the network topology, why does it have to consult an external router to forward a packet? Doesn't it have its own forwarding table? I remain unenlightened, and appreciate clarification.

We have currently 7 5500's with RSM's, and I tell you it is doing all of the routing for us to include VLANs. Lot's of then. What I am trying to say here is that I can Route between VLAN's just fine with an RSM. I think that someone missed typed RSP with RSM.

NTP synchronization
Is there a command to force time synchronization ? Cheers
2nd time...Passed BSCN Review {long}
For what it's worth, posting a second time...
{Posting thru nntp, if that matters?}
BSCN review
Test : BSCN 1.0
# of Questions: 61
Score : 850
Passing score : 690
Preperation : A bunch!
Exam Prep
Specifically, I took the BSCN 1.0 class through
IMS http://www.imsinc.com/ two weeks ago. Not
an indorsement, just stating where I went. The
class started off kind of rough, as the
instructor did not show up until 1pm on the
first day...travel probs. Additionally we had
a power outage for approximately 4 hours later
in the week. Luckily, I did not pay for the
class directly...work tuition reimbursement.
I took the test this past Thursday.
The class covered the meat of the material. I
think more importantly, it allowed you to
configure the commands on the routers. And at
this time, that worked out for me as my lab is
in a _Public Storage_ facility, until we move
into the house.
Self Study
BGP BGP BGP. Haven't done the ISP thing {yet!}.
This was my biggest lacking.
BTW, thanks go out to the 3 guys who replied
to my BGP Sync Next Hop thread. I wish it had
spawned a bit more conversation in the group...
thought it was a good question...ah well. ;-)
I gave OSPF about 1800 ticks of my study time,
due to experience. However, check the links
section at the bottom for OSPF stuff. All my
OSPF books are also in _Pub Storage_
facility, so I sorta winged it there, with
the class being my reinforcement.
EIGRP reinforcements actually came from the
course. And while I had experience with
EIGRP, I didn't know things like the HELLO/
Update/ Query/ Reply/ Ack packets. So if
you don't either...search Cisco. ;-)
VLSM...you are _EXPECTED_ to know it. Both for
the test and for the class. Not a problem for
me, but if you don't have it down tight, you
need to. Both the test the class EXPECT you
to know how to summarize {supernetting}.
Experience
First 10 years, I did long haul telecom. T1
guru, back when T1 was considered High speed.
Luckily I saw the writing on the wall, and
hi-jacked into the Networking scene 5 years
ago.
During those 5 years, I had to clean up other's
messes...5 users with a /24...that kind of stuff.
Discontiguous networks etc...all the while
integrating non-Cisco gear into the mix. So
I ended up buying 2 books from Amazon on OSPF,
had 10 days to figure it out implement it.
You either beat the learning curve or you
don't! ;-)
Well, that's about it. I got 100% on the IP portion;
I think that was the VLSM/Summarization. The funny
part was I got an 85% on OSPF, and 88% on BGP. Well,
it's funny to me, because I feel I should _know_ OSPF
better. ;-) Still wondering what I missed on OSPF.
BRCAN will be _my_ hard test. Half the time I mis-spell
TACACS ;-)
Good luck all...

Re: EIGRP IGRP
Emilia, Simply to clarify things a bit. No, the 170 is the eigrp metric.. that is calculated using five values(bandwidth, delay, reliability, loading, and MTU) this is a 32-bit number used to calculate the metric for a route which is how eigrp knows which path is the best route and it also give you the flexibility to manually adjust the metric to make routing decisions. The 90 is the administrative distance for the EIGRP.

RE: Switches !!!
Frank, I had the same problem as you did with the concept before. I believe that Sean and Chris are both talking about the same thing. RSM module is essentiality a router that is design to route between VLANs instead of networks. Remember, there are many kinds of switches. (Ethernet, Token Ring, ATM) Main purpose of VLANs is to limit broadcast (that's what most of us use it for but there are other uses like security). From a design point of view and to keep it simple. At the access layer, each switch will have one VLAN. At the distribute layer you would have switches with RSP in it. It will function as the security, switching/routing between the VLANs. At the core layer, you can have only switches. All broadcast had been stop or change to unicast at the distribute layer. In a WAN situation, those switches could be ATM. If you have no broadcast in your network at all, you can do without the RSP and the VLANs. I am not sure how such a network would work but Howard or Priscilla can probability tell you. I hope this helps. A really good book to read about switching is CCIE Professional Development: Cisco LAN Switching.

He claims that the initial route needs to be found by a router and then the RSP can take over. I still have a problem with this concept because I have read about networks consisting entirely of switches from access layer up to the core layers, and switched across WAN's too!!!

In the second part I believe Sean is speaking about Netflow switching where the router determines how to route a source/destinatioon once, and once the switch learns how that packet was routed through the switch, the next time it recieves a similiar source/destination that normaly would require route processing it will just switch the packet to the appropriate port based on what it learned the last time without asking the router to process a route. -Original Message- From: Frank Wells [mailto:[EMAIL PROTECTED]] Sent: Friday, August 11, 2000 12:30 PM To: [EMAIL PROTECTED] Subject: RE: Switches !!!

Delay !!!
Title: Delay !!! Can somebody explain me what is delay ?? I mean the round-trip time of the packet, Is it different from media to media or it is not media-specific, secondly can I know out the links VSAT/DDN which is having a more delay over the other. We have a VSAT link 64 kbps to one of our site and a 64kbps DDN to another site the response of the DDN is much better than the VSAT. Normal pinging to the site connected through DDN is 40-50 miliseconds with one hop. Normal pinging to the site connected through VSAT is 500-600 milliseconds with one hop. Path Delay value=Link delay + Repeater Delay + DTE Delay + 5, If PDV512 the communication path is ok. Link Delay=2 X Segment Length X Cable Delay in BT/m Is the same formula applicable for WAN links, VSAT etc or it is just for ethernet networks. Pls. explain. Thanks in advance.

RE: Switches !!!
Title: Switches !!! A.1 If you want to telnet into the switch you should give the switch an IP address. This IP address should be applied to VLAN 1. "Administrative Interface" A2 The NIC on the PC will broadcast their MAC address to the switch. You're getting the correct picture. However, if for some reason you are not being able to communicate between both PC's you need to check the port assignments on the switch. All ports should be assigned to VLAN 1 by default. If the ports are not asigned to the same VLAN they are going to be on seperate broadcast domains. This means that in that case you'll need a router to do the job. I try to be as simple as possible.

Compressing IOS Images with MZMAKER.EXE
Group, A while back I read about a utility that would compress an IOS image, but still allow you to use it. I found that I had archived a copy on a CD, so I tried it out. It compressed a 14MB image down to 4.5MB. I TFTP'd the compressed image to my 2524 and it rebooted. Upon reboot, however, it wouldn't boot from the image. I don't recall what the error message was (something along the lines of bad CRC), so I removed that image and replaced it with an uncompressed IOS. Has anyone else used this or a similar program? I'm including a link to the file. I'm told it's freeware. The link is only up for a week or so, but it's on my public share (rtimmons) at xdrive.com, and I'll leave it there indefinitely.

Re: Any difference between secondary address and subinterface fora port?
Well from my understanding a subinterface would be better from an administrative point of view. I.E. Say you want to run two IPX networks on the same physical interface using the secondary command. If you where to change the encapulation on the phsyical interface you would affect all IPX networks. Now if you where to have a subinterface this can be avoided. The IOS sees these subinterfaces and different logical interfces on the same physical interface. To round it up, you can perform differnt functions on a subinterface. IF you where to use the secondary, anything you change to affect the interface would affect that secondary addres bound to it. Group correct me if i'm wrong, or sorta right.

Hi 3900 TR switch, why? Because it is on the lab. Good luck finding one... 25xx TR routers. Cat 5K with ATM LANE and ISL,1.q, why? Because it is on the lab. The price is high, you might want to look at a virtual rack. Another 2600 or 3600 router with ATM and VoX, why? Because it is on the lab. Again there is a high price for these and might want to consider a virtual rack. A 4500 or 7000 to act as frame switch. Why, you will be dealing with FR on the lab, plus there will be at least one 4x00 router in the lab. LS 1010, 100, or 2020, so that you can have ATM to connect to your other ATM equipment.

Re: EIGRP IGRP
170 is the administrative distance; the metric will be based on the metric components (as you describe below) that are used with the redistributed routes. EIGRP is the exception for interior routing protocols that has a different administrative distance for exterior (read: redistributed into this protocol) routes, so that routes redistributed into EIGR will be less "believable" than routes directly learned from another interior protocol. Nice feature if use is understood. (And for more fun, remember that an EIGRP summary route has yet another administrative distance, 5, to make it more likely to be used. Don't forget that the longest match rule takes precedence though over administrative distance - longest match first, then administrative distance then metric.) "Nigel Taylor" [EMAIL PROTECTED] 08/13/00 08:03PM Emilia, Simply to clarify things a bit. No, the 170 is the eigrp metric.. that is calculated using five values(bandwidth, delay, reliability, loading, and MTU) this is a 32-bit number used to calculate the metric for a route which is how eigrp knows which path is the best route and it also give you the flexibility to manually adjust the metric to make routing decisions. The 90 is the administrative distance for the EIGRP.

Re: where is routing table located in the router?
An article said the routing table is located in RAM. Correct. I got a little puzzled ,cause if the router is powered off by accident, will the table get lost totally? Yes, with the caveat that static routes are an _input_ to the routing table. If the router is a backbone one,the table should be very big ,so after the power cycle ,the router has to attain all the routes once again,it's time consuming. Yes. In a default-free Internet router with a full routing table, you'll see times of several minutes based on the number of views and the complexity of filters. On the other hand, a serious Internet backbone provider will have more than one router. In an enterprise environment without extensive Internet routing, the initial convergence time may still be noticeable, but could be in the tens of seconds or low minutes. Does the router put some static routes in NVRAM or flash , Yes. NVRAM. or all the routes stay in ram ? If you know the routes are stable, then you certainly can use static routes. If you aren't sure about them, however, how do you know the routes you've kept are still valid?

OT: Employment decisions...
First off: Long time listener, first time caller :o) Thanks for all the thought provoking discussions! A little bit of background. I have been in the computer industry, in various capacities, for 10 years. Specifically I have been in IT Management for the last 4 of those 10 years. The first 6 spent doing everything from hardware support, desktop and server support, network support, consulting, and programming. I have a wide range of experience, however I am currently looking to specialize in the internetworking side of things. I am getting ready to take my CCNA 2.0 and then go on and pursue the CCNP. I have fairly limited hands on experience in routing and switching in the past (mainly small shops), and currently in IT Management I do not get as much as I would like. My question for the list: Should I go ahead and start looking to get out of IT Management and into a more hands on routing/switching job as I pursue higher Cisco certifications? Given my limited hands on experience in hardcore routing/switching, can I expect a fairly significant pay decrease when switching specializations? I guess part of me thinks that it would be beneficial to go ahead and get into the field I want to end up in - the more experience the better. The other part thinks that sticking with the good money now will make it easier to fund my home Cisco lab :o) Thanks guys, Ed Williams -- Edward S.

Re: where is routing table located in the router?
The routing tables are held in RAM. The time to build a table is not very long, were talking miniscule. If the table is large, say it contains BGP routes, it could take a a few seconds. It rely depends on the processor in the router and the routing protocol. Route tables are supposed to be dynamic in nature. As to the power cycle, it takes longer for the router to come up than to learn the routes it needs to communicate.

Routing and NAT config problem
Hello everybody, I have been given the task to enable two separate company's to a vlan on our internet switch. Both company's will use a ISDN link to one 2600, with the eth interface of the router in the internet vlan. So far so good, and no problems configuring. But on comes the challenge. the two company's lets call them foo and bar both use the same IP addressing scheme. For the sake of the argument lets use 10.0.0.0/16 (which isn't far of the truth) From those networks clients will be browsing via the isdn link the services in the vlan, and servers in the vlan have to update systems on both the foo and the bar network. the problem, I can do host routing so the servers on the vlan will be able to contact back office systems on both foo and bar networks, but how to make users from both networks able to browse the network?? As far as my knowledge takes me the inside to outside our outside to inside nat overload, which will do in the case of just one interface will not work here. I could make a different pool for both networks, but how to make sure the foo and the bar network get their nat addresses from those different pools? Hope anyone can lead me in the right direction.

CPA-2509 (2nd try)
I have an opportunity to pick up a CiscoPro 2509. I have physically examined it, but I haven't fired it up yet (I will try to do that soon). The box contained router, power cord, console cable, and docs. This one had the funny multiport plug for the async ports, but didn't include any serial cables (async or sync). The problem is that I need to determine the value of it. Checking eBay indicates that regular 2509's go for about $800 to $900 US, and checking the groupstudy archives people are suggesting that CiscoPro devices are worth about have of the equivalent regular Cisco device. So, I'm guess at a value of approximately $400 to $500 US for this device. Would this be a fair estimate?

canonical and non-canonical addresses
I am having a problem understanding the issues between canonical and non-canonical addressing. I understand that the bits are flipped within the byte. On page 32-33 of Interconnections Second Edition she gives the example of the address a2-41-42-59-31-51. Canonical: 10100010 0101 0110 01011001 00110001 01010001 Non-Canonical: 01000101 1010 0110 10011010 10001100 10001010 If you look at this you can clearly see that the address in canonical format is not a group address (last bit of first byte is zero) but in non-canonical format it is a group address. At this point I can see a big problem because she also states: ".the group bit in addresses was defined not as "the most significant bit" or the "least significant bit" but rather as "the first bit on the wire." Thus, an address that was a group address on 802.3 would not necessarily look like a group address when transmitted on 802.5 because a different bit would be transmitted first." Here is the confusion: In canonical format the least significant bit is transmitted first and in non-canonical format the most significant bit is transmitted first. So on the wire the 1's and 0's would be in the same order. Here is an excerpt from RFC 2469: The figure below illustrates the difference between canonical and non-canonical form using the canonical form address 12-34-56-78-9A-BC as an example: In memory, 12 34 56 78 9A BC canonical: 00010010 00110100 01010110 0000 10011010 1000 1st bit appearing on LAN (group address indicator) | On LAN: 01001000 00101100 01101010 0000 01011001 0001 In memory, MSB format: 01001000 00101100 01101010 0000 01011001 0001 48 2C 6A 1E 59 3D This shows that no matter how the information is stored in memory it looks the same on the wire. So if it looks the same on the wire wouldn't an adapter pickup the packet and flip the bits in the byte if it needed to. Since it on the wire it looks like the bits are in non-canonical format a canonical format media would automatically take the first byte and flip the bits and so on, or so I would think. If anyone can figure out where I am going wrong please let me know. If it would be best to talk, email me directly with a daytime phone number and I will call you. Thanks.

Upon reboot, however, it wouldn't boot from the image. I don't recall what the error message was (something along the lines of bad CRC), so I removed that image and replaced it with an uncompressed IOS. Has anyone else used this or a similar program?

I don't have any documentation for this product. Yes. Even Cisco's "run from flash" hardware (2500, old 1600, etc) will boot a compressed image in to RAM. This is an "undocumented feature". MZMAKER.EXE uses the same algorithm as the unix-based "compress" tool. I've used this (compress, not MZMAKER) on numerous IOS images, and never had anything but success. Usually, though, if I'm looking to skimp on flash for lab purposes I'd just end up using a tftp server. ___ 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] ___ 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]

RE: 2924XL and 2600 Trunking problem
Nope, I don't have VTP configured at the moment. I have a SWAG of my own, too. I think it may be due to the fact that I have no ports configured for VLAN2 that are up/up. My guess is that if I were to go grab someone's laptop and connect it to a port in VLAN2, then it would allow me to do a "no shut". That seems like strange behavior to me, though.

RE: Switches !!!
I don't believe this is correct. "Layer 3 switching is hardware-based routing. In particular, the packet forwarding is handled by specialized hardware, usually ASICs. Depending on the protocols, interfaces, and features supported, Layer 3 switches can be used in place of routers in a campus design... Cisco's Layer 3 switching implementation on the Catalyst family of switches combines the full multiprotocol routing support of the Cisco IOS software with hardware-based Layer 3 switching. The Route Switch Module (RSM) is an IOS-based router with the same Reduced Instruction Set Computing (RISC) processor as the RSP2 engine in the high-end Cisco 7500 router family. The hardware-based Layer 3 switching is achieved with ASICs on the NetFlow feature card. The NetFlow feature card is a daughter-card upgrade to the Supervisor Engine on a Catalyst 5000 family multilayer switch. " This from http://www.cisco.com/warp/public/cc/so/cuso/epso/entdes/highd_wp.htm Also, from the BCMSN course notes, "An alternative to using a layer 2 switch and a layer 3 router is to use the next generation of LAN switches, called layer 3 switches. These new switches integrate layer 2 and layer 3 functionality in a single box". My understanding is that an RSM/RSFC/MSM is a full-featured router on a card. If it swims like a duck, flies like a duck, and quacks like a duck, I don't care if it's called Layer 3 switching. As far as I can see, it's just missing a few tail feathers in the form of WAN interfaces - it can still fly like a duck, just not over long distances :-) JMcL -- Forwarded by Jenny Mcleod/NSO/CSDA on 14/08/2000 10:27 am --- "Odom, Sean/SAC" [EMAIL PROTECTED] on 12/08/2000 03:03:10 am Please respond to "Odom, Sean/SAC" [EMAIL PROTECTED] To: "'Frank Wells'" [EMAIL PROTECTED] [EMAIL PROTECTED] cc:(bcc: JENNY MCLEOD/NSO/CSDA) Subject: RE: Switches !!!

Unless the external route router must be used as a gateway to leave the local boundaries. To answer your question, a switched network must still use an external router for Layer 3 resolution.

I know that they are working because when I dial from an outside line the circuit shows that no bearer channel is avaiable on the incoming call. Cheers Patrick

Re: WICs
I no longer trust "Hot Swappable". Now Cisco said that Network Modules are hot swappable on a 3662. Just to make sure, I asked 2 different peoples. I need to install a WIC into the Network Modules. I pull out the Network Modules, install the WIC. The router was fine until I insert the Network Modules back into the router. The router was SO nice to reboot itself for me. If the router is only carry data, no one outside of the network department may had know. NO, this router also carry voice traffic. Guess what, I cut off the President of the company. For me, there is no longer anything as "hot swappable". Power everything down then insert/remove anything.

Re: where is routing table located in the router?
Interesting question. Yes the routing table is dynamically built by routing protocols. There are also static routing entries if you created in your configuration file. Locally connected active networks will be entered into the routing table immediately after the reset. If the question goes to how the router performs routing using routing table, its different. In the Cisco Express Forward mode, routing table is consulted for the first packet of a given destination. IOS will store the forward(port) information in the module/adaptor card RAM. Subsequent packets target to the same destionation will be forwarded to egress port without going through the routing table.

RE: Ghost sessions on vty ports
Craig, I have had a problem somewhat like that before. What I had to do was to change the exec-timout time. I did not have anything stated in the router, and as soon as I applied the exec-timout 3 command it fixed the problem. It seems that your sessions don't have an expiration time, and sometimes just by closing the telnet window your're not closing the actual session. I would also try to upgrade to a knewer IOS.

RE: Switches !!!
I have to say that I'm a little confused my self! RSP "Route Switch Processor" is used by the 7500's RSM "Route Switch Module" can be used by Cat5500 for example. We have currently 7 5500's with RSM's, and I tell you it is doing all of the routing for us to include VLANs. Lot's of then. What I am trying to say here is that I can Route between VLAN's just fine with an RSM. I think that someone missed typed RSP with RSM. Paulo Nahhh... The guts of a RSM and RSP are the same. The RSM connects to a Cat5000 bus and can have its own WAN interface. The RSP connects to a CBus in a 7x00. There are also faster RSPs available than RSMs. ___ 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]
Re: Any difference between secondary address and subinterface for a port?
Secondary addressing and subinterfacing serve different purposes. In my less than humble opinion, the major applications for secondary addresses are workarounds for problems caused by the dinosaur of classful addressing. These are discussed in detail in Chapter 5 of my _Designing Addressing Architectures for Routing and Switching_, but some applications include: -- making more hosts available than are available with a fixed subnet mask -- fixing discontiguous networks -- dealing with especially stupid host stacks that assume default masks The underlying concepts of secondaries and subinterfaces are different. Secondaries (called multinets in Bay-speak) map multiple subnets/networks to a single broadcast domain, NBMA medium, or point-to-point link. Subinterfaces separate the broadcast domains on a medium with layer 2 multiplexing (e.g., DLCI, VLAN ID, ATM VC, etc.). There are some complex VLAN configurations where it can even be useful to have secondaries on subinterfaces. Personally, I shudder at the thought.

Traffic threshold for BGP?
Here is our BGP setup with a single ISP: external 7507 router (EBGP, AS yyy)) || | 4 T1's | 1 DS3 || ISP router#1 ISP router#2 (AS xxx) (AS xxx) Here's what's happening: All inbound/outbound traffic is going through the DS3, and no traffic is going through the T1s! Here's what the manager wants: Load balancing with the DS3 and T1s (T1's not a backup mechanism). He wants all 5 circuits to be used all the time. He wants the T1's to be used first, for example, and when the load reaches 50% on them (or any other %), the DS3 gets used. Kind of like dialer-load threshold with ISDN ;-) I'm not aware of anything like that, are you? He specifically wanted me to ask that question... But I was thinking that the only way you could do load sharing is have the T1's be preferred outbound (higher local-pref than DS3) and the DS3 inbound (lower MED than T1). Currently on the router the route-maps set both local-pref and MED inbound/outbound on all circuits!

As the maximum spec for HSSI is 50 feet, I would like to know where we could avail of one that long, or at least around 20 feet.

I do not think Cisco would discontinue the use of secondary IP addresses.
