RE: IPX Network addresses [7:11990]
Priscilla, As usual you have such eloquent ways in explaining concepts. But as you mentioned earlier that the IPX net addresses are manually configured (preferred method?), you're implying that i can change these different addresses to be the same IPX network address but with different encapsulations, corrext? I think i'll put this to the test as soon as i have time to get Sniffer running again. Thanks for your insight.

They are not different representations of the same network number. They are different networks. Broadcast domains have nothing to do with it. If all devices in these four networks are connected via hubs or switches, they see each other's broadcasts. They process the broadcasts at the data-link-layer and only process them further if they are running the same Ethernet frame type. If these are really internal network numbers, then the question is moot. Internal network numbers don't need a frame type!?

What's happening here is that the new server has every single Ethernet frame type loaded, and as a result is using different IPX network number for every frame type. New 3.x and 4.x servers will do this if you perform an install using all the defaults. You need to run INSTALL (or NWCONFIG if 5.x), edit the AUTOEXEC.NCF and remove all BIND statements referencing frame types you don't want to use. Ethernet_II is preferred. NetWare 5.x is more restrained and tries to use IP only.

Here is the fix, and I am almost ashamed to say, but I want to pass this on so none of you all fall into the same trap as I did. As I said, in one post before, I kept getting the same error messages even after TAC sent me new memory and a new router. The 3rd TAC engineer was the charm, because he asked me if this was a TELCO version of the 3660. That was a real good question cuss I had no idea, as I have never worked on one. Well, that was the problem, it takes a TELCO FEATURE SET IOS. One telltail clue is that their is not a plastic front on the Telco version. I saw this right off the bat, but thought Cisco had just redesigned it. Man what a day. The other way to see if the router is an Enterprise version or Telco is to run the SN numbers. I can think off all the times i do this before I install an IOS. Maybe i should. Good news is I got it fixed and got a new Router out of the deal (thanks you TAC). And as TAC goes, they have pulled my Butt out of the sling more then once, so I have nothing but good to say for them. Yes I have gotten some DORKS before, but I have the option to tell them to get lost and give me a new Engineer. We pay a lot for this service.

LSA type-5 suppression across OSPF area boundaries?? [7:12189]
hi all, have a problem that has been nagging at me for a good long time now... say you have a pair of ABRs sitting at an OSPF area boundary, and an ASBR is originating Type-5 LSAs from inside the non-backbone area. Is there an easy way to suppress the propagation of the type-5s outside the area? I would have a range statement on the ABRs to advertise the area aggregate, I just want to suppress the more specifics. I have tried using 'distribute-list out ' which would do it for me, but for some reason IOS won't allow this with OSPF: router(config)#router os 1 router(config-router)#distribute-list 1 out FastEthernet 0/0 % Interface not allowed with OUT for OSPF router(config-router)# I suppose that allowing this could potentially screw up routing if done without some care, but JunOS lets you do exactly this sort of thing - you can produce some wacky policies, but at least you have the option ;-) btw - I know I could prolly do this with multiple OSPF instances and redistribute between them, but I *really* don't want to get into this level of complexity. thanks in advance - this one has been driving me mad Andy Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=12189t=12189 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Trace failure indication [7:12191]
Have you checked duplex? Sometimes speed and duplex settings have a similar effect. Things seem to work properly, but you are dropping packets which slows the application down. Obviously if you have one end at 10 and the other is at 100, you will run into major issues, but sometimes autonegotiation is flakey. If you are using auto on both devices, check the interface for speed and duplex it auto'd to. If this is across a serial link, what is the bandwidth? Also, is this a core router that stays fairly busy? what is it's utilization? Sometimes routers will drop pings if they are busy. -Patrick JHIGGINS 07/12/01 04:01PM When I trace from a cisco router to another Cisco router I get a timeout failure every other probe on the last hop It fails on every type of cisco router I have tried, 7513,25xx abd 36xx.

RE: IPX Network addresses [7:11990]
Perhaps I was unclear by my meaning. A station running Ethernet II that receives a ethernet_Snap frame discards it. It is unintelligible. This is was what I meant by being in separate broadcast domains. A router or server advertising services to more than one frame type has to generate a separate advertisement broadcast for every frame type, thusly It is reasonable to say that each frame type creates a separate broadcast domain. (Same wire, separate domains.) The question is rather blurry though. If it truly is a separate broadcast domains, then the NIC should discard the frame without generating an interrupt. If it passes it to the o/s to discard, then I'm not sure what it is?!

Re: Giles, 2nd Edition Errata [7:11858]
John, Maybe I wrote in a little too strong words about the Giles Book .But is just that I made the mistake of spending $ 85 on this book .But that was not my worst mistake .It was going through it . I ended up totally confused about what I needed to know for the written . But I work at Cisco and know a few CCIE's and all of them recommended that I stay off Giles .

It has nothing to do with frame types. This is was what I meant by being in separate broadcast domains. A router or server advertising services to more than one frame type has to generate a separate advertisement broadcast for every frame type, thusly It is reasonable to say that each frame type creates a separate broadcast domain. (Same wire, separate domains.) That's not what is normally meant by a broadcast domain. Any station on the same switched or repeated network hears each of the broadcasts. If the device were on the other side of a router or in a different VLAN, it wouldn't hear them. The device would be in a different broadcast domain. The question is rather blurry though. If it truly is a separate broadcast domains, then the NIC should discard the frame without generating an interrupt. If it passes it to the o/s to discard, then I'm not sure what it is?!

RE: The Proxy ARP process [7:12198]
What it is: Proxy ARP is a method by which routers make themselves available to hosts that do not have a configured default gateway. Proxy ARP is enabled on Cisco routers by default. no ip proxy arp is the command to disable Proxy Arp on a per interface basis. Consider the following: Host A (192.168.1.2/24) needs to send a packet to host B (192.168.2.2/24) located in another network. A router with two ethernet ports connects to the 192.168.1.0 network on its first Ethernet port, and connects to the 192.168.2.0 network on its second Ethernet port. 192.168.1.0 192.168.2.0 Network Network Host A---Router--Host B .2.1.1 .2 Host A does not have a configured default gateway, and therefore does not know how to reach a router to connect to hosts outside the 192.168.1.0 network. Consequently, it may issue an APR request for 192.168.2.2. The router, receiving this request on Ethernet 1 (with Proxy ARP enabled), and knowing how to reach network 192.168.2.0, will issue an ARP Reply with its own MAC address in the hardware address field of the ARP Reply. In doing so, Host A believes that the router's Ethernet1 interface is the interface of Host B.

Hi, You might find that the HP Openview databse still has an entry for the port in an other layer in the model. Do a search for it in the edit mode and then you will need to delete it.

Re: LSA type-5 suppression across OSPF area boundaries?? [7:12212]
Could you accomplish this by making the area containing the ASBR a stubby area? IIRC, you can put an ASBR inside a stubby area but the Type-5 LSAs will not leave the area. I'm not sure about that, but I'd swear I read that somewhere recently. Okay, I just checked this in Giles, 2nd edition. According to him, the above is true.

I was configuring an ISDN link yesterday/today and I just recently read something saying to turn off WFQ also Mike W. Charlie Hartwell wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... It would be interesting to see the document that recommends that action - after all, WFQ is designed to help with low bandwidth links without the need for complicated config. It is more likely that it is recommended to turn off WFQ when using ppp multilink across the ISDN connection. This is probably to avoid any unnecessary fragment delay which could lead to malformed packets and retransmissions. So in answer to your question, there is no real connection between BRI performance and WFQ but cisco probably recommend disabling WFQ to avoid other problems.

RE: Security Specialization (PIX) [7:12129]
Until recently there seemed to be very little available training for PIX's. It was just a small portion of the MCNS course. You may already know this, but just in case: Cisco now has a new security certifiction as of a couple of months ago. They now have a separate full-blown class on the PIX, which logically would mean that even if you don't want to attend that class, you might be able to get the course material from Global Knowledge or Cisco Press. If you can get a copy of the MCNS 2.0 materials, that would probably be a good thing too. Hope that helps.

BRICKS - I need 'em. Seen 'em? [7:12221]
I know this is going to sound unusual, but I figure as much traffic as this site gets, SOMEBODY must have an answer. Several months ago, I was in an ACRC class, and the instructor had a little program that consisted of a bricks server and bricks clients. I believe this was a Windows app. The way it functioned was essentially that you could define what each brick represented such as TCP, UDP, or other packets, what size, and modify virtually any parameter of the bricks. The clients would then pull the bricks from the server, giving show on the monitor a graphical representation of bricks stacking up, with the speed varying as changes were made to the network. It was used in tha class to demonstrate queuing and some other performance-tuning issues. I would like to get my hands on that program, or something very similar if anyone knows where I could obtain it. I want to use it for demonstrating graphically to upper management and others, some plans that I have for network reconfiguration. I can show them utilization stats all day, but I really think the bricks might make it clear to them. Any help is appreciated.

Hi,
Priscilla, thank you very much for the info.
I was hoping for your response for I always enjoy your email on the mailing
discussion.
In fact I enjoy reading your DCN book. It is informative straight to the
point.
In fact I used for reference for some of my propsed solution.
The regional project I am handling was having problem with Port Monitoring
and the customer has various types of Cisco switch. I faced this problem
for the Cat6000 when SPAN was enabled. I guess I need to study further
how to configure the SPAN to I understand the SPAN work on the Cat6000.
When SPAN was enabled on Cat6000, the LAN EIGRP routing entries were
lost on the Router Ethernet port. I guess I have to configure the CAT6000
to forward the EIGRP multicast traffic and other types of traffic. Thus,
this is not a workable solution for my customer to go through all these.
Thank you have a great weekend.

Based on the above diagram for simple discussion.
Does that means EIGRP routing entries will be discarded at the Switch Port1
not updated to the Router
I am assuming that EIGRP multicasts arrive from the router at switch port 1
in your diagram, and port 1 is the monitored (mirrored) port and port 2 is
the monitor port where the analyzer resides. You will not see the EIGRP
multicasts on the destination (monitor) port 2 when using a Cat 1900. The
EIGRP multicasts should go out all other ports on the switch (depending on
VLAN and other configurations.) So, it won't cause any operational problems
on a network. It just makes monitoring difficult.
Note that EIGRP uses multicasts for hellos. It sends routing updates
directly to neighbors, so you would see those on the monitor port.
Ethernet port? Similar CDP, Multicast Video streaming, Mainframe
application, ...etc, will not able
to pass through the Monitored port?
I also do not see CDP on my monitor port on my Cat 1900. I haven't tried
multicast video or other applications.
Lastly, is there a way to enable all traffic to flow through the Monitored
switch port?
Well, it blocks unregistered multicasts. Theoretically you could
register the port to receive multicasts. I don't know how, though. IGMP?
Sorry, I don't know more about this. I'm just discovering the problems
myself. But I think it's just a Cat 1900 problem.

Hope to hear some comments on this. Apprecaite the inputs.

RE: LSA type-5 suppression across OSPF area boundaries?? [7:12235]
I agree with the last post. We did this similar simulation in a lab setup for pre-production implementation on our network. NSSA area works great.Keeps LSA type 7's in the NSSA and then if you want you can translate type 7's to type 5 LSA's at the ABR to area 0.0.0.0 Good reference is John T. Moy's OSPF Anatomy of an Internet Routing Protocol and Cisco Press Routing TCP/IP Volume I.John's book gives you the industry standard view of OSPF and the Cisco Press book will give you Cisco specific issues as well.

RE: LSA type-5 suppression across OSPF area boundaries?? [7:12236]
Setting up the ASBR in an NSSA area will work. We connected a Nortel CVX to two Extreme Networks Layer 3 switches acting as the ABR'S then off to two more layer 2 switches then to two Cisco 7200 routers in a lab. We were able to keep the LSA type 7's in the NSSA area. It works just fine. With the Extreme L3 boxes we could use the translate option to translate LSA type 7 to LSA type 5 through the ABR's.

questions on IPSEc - realworld implementation [7:12238]
Hello - I got some questions on IPSec, wonder if some gurus here can help me out. The questions are not about how to set it up, but rather why you would want to set up certain options. I hope somebody can answer any or all of these questions: 1) Cisco routers allow you to create a tunnel with both AH authentication and ESP authentication (not ESP encryption, but ESP authentication) at the same time. Considering the overhead involved (more SA's have to be built, packet gets longer, etc.), why would you ever want to combine them? More specifically, since AH authentication is stronger than ESP authentication (because AH actually checks the integrity of some IP header fields and ESP does not), then provided that you have already decided to do AH authentication, is there ever a good reason to also do ESP authentication as well? I agree that AH authentication combined with ESP encryption is something good to do, but would you ever want to combine AH authentication with ESP authentication? I'm sure that there is a good reason to do this, could somebody tell me what that reason might be? 2) Can anybody come up with a reason to use a transformset with the keyword esp-null, which is no encryption at all? OK, I understand you might want to create a tunnel with just authentication, and no encryption. Fine, I have no problem understanding that. But then, why not just leave out any encryption keyword (ergo - just don't type esp-des or esp-3des), which seems to me would do the accomplish thing as typing esp-null? Maybe that's just a question of semantics, but it seems quite odd to me that IOS would have a command that does the same thing as typing nothing. 3) As a real-world consideration, is it true that AH is essentially becoming unpopular, and the industry as a whole is consolidating around ESP?

I have 2 routers on the same ethernet LAN (with configs for a wide area network) and I was trying to get the routers to use OSPF to update and distribute the respective routers route tables. However, this did not work. 10.10.30.0|-| int e0 10.10.10.1 255.255.255.0int fast 0|---| 10.10.20.0 | |- -| |- int bri0 |-| |_| int bri0 router 1603 router 1720 This is my setup, I know very cheap. I can get the routers to ping each other and also sh cdp info, but I cant see route updates. This is the command I entered on both 1603: 1720: router ospf 10router ospf 10 network 10.10.10.0network 10.10.10.0 network 10.10.30.0network 10.10.20.0 I checked the sh ip route and could not see anything indicating the routes were known Any help ???
