Re: EIGRP Mystery??
Hi Denis,
Do the 4 remote networks show as Active in the EIGRP topology table ("sh ip
eigrp top" then look for "A" next to routing entries
With a relatively large network like yours the EIGRP quiery boundry for the
DUAL algorithm may be causing 4 of your routes to get "Stuck in Active"
Do the remote sites have a full routing table, or just a summary / default
produced by the core routers - if full table then check your bandwidth
settings on the edge routers. Eigrp will only use 50% (or ip eigrp-bandwidth
X) of the _configured_ bandwith that a link has.
This has happened to me before, where although the site has 32k, for some
reason the configured bandwith on the serial int was 3.2k (typo in config)
and thus the eigrp process forced itself to use 1.6k for all routing updates
and hellos. consequently adjanceys dropped despite the pvc remaining
operational.

Stupid Cat 5xxx question
I've just read (and never noticed on the 5500 we have at work), that the 5xxx series has a RS-232 console connector (I assume this to mean DB9 or DB25) that requires the use of a rollover cable (it did not say null modem), so I guess that means I need two DB25/DB9 to RJ-45 connectors and a rollover between them to log on through the console port.

Router 1 is the ABR that connects to the backbone, Router 2 is the ASBR that is redistributing some IGRP networks into area 4 and Router 3 is just an internal area 4 router. They are connected together over one ethernet. I would like to set the "P" bit on the type 7 LSA's that the ASBR produces to zero, so that the ABR (r1) will NOT convert these to Type 5's and NOT put them into the backbone (see Doyle, p483 if you dont know what I mean) the closest command I can come up with is the "area 4 nssa no-redistribute" , which I thought would work when I typed it in on R2 (the ASBR) - but this seems to block the production of the type 7 LSA altogether, so that R1 and R3 can no longer see the IGRP routes at all If I type the "area 4 nssa no-redistribute" on the ABR (R1) then this has no effect whatsoever, and the type 7 routes still get converted to type 5, and flooded into the backbone. Doyle says this command should be implemented on the ASBR not a seperate ABR so this doesn't surprise me too much Does anyone know how to do this? _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

WAN Protocols, Connection Oriented V Connectionless ?
Hi, Does anyone have a link for a definitive comparison between cnnection oriented versus connectionless WAN Protocols ? e.g SDLC, HDLC, HDLC (Cisco), LAPB, PPP. I realise that SDLC, HDLC, LAPB, PPP are all in effect the same frame format and I´m thinking they should all be connectionless allowing higher level protocols like TCP to provide the reliability. I have some confusion though with the similarity with IEEE 802.2, i.e I´ve read that PPP contains a control field of 03 making it connectionless. However, if an application used 02 in the control field it could presumably be connection orientated. i.e it has the ability to support both. Any thoughts ? Regards, Phil. Do You Yahoo!?

It is my belief that the P bit is unmodifiable. Type 7's are advertised as 5's to the OSPF domain in almost if not all manufacturers equipment.

What kind of traffic is being passed? You can set it up so that ip traffic or whatever traffic keeps the line up. Or you can use "dialer idle-timeout 3600" command to specify the amount of time the link is up after it comes up. We use an access list to bring up a connection i.e. "dialer-list 1 protocol ip permit" with this, any ip traffic will bring the link up and it will remain up for 3600 seconds.

I have some confusion though with the similarity with IEEE 802.2, i.e I´ve read that PPP contains a control field of 03 making it connectionless. There are additional cases of 802.2. Class 1 is indeed connectionless and unreliable. Class 2, which essentially is SDLC over LAN, is connection-oriented and reliable. Additionally, the Manufacturing Automation Protocol suite has a variant, 802.2 class 3, which is connectionless but reliable (i.e., acknowledged datagram). This is a very special application intended for real-time robot control, an application in which it would make no sense to route the traffic. However, if an application used 02 in the control field it could presumably be connection orientated. i.e it has the ability to support both. Yes, it could be connection-oriented.

Re: GRE VS. IPSEc
Liwang, You aren't comparing apples to apples in your questions. Let me see if I can shed some light on the subject. IPSec is a VPN technology that is responsible for securing a data stream between two VPN peers. It does not provide multi-protocol support, so if you need to transport anything other than IP, you will need to use a GRE tunnel. (assuming you only connect to the outside world using IP) A GRE tunnel does not provide any security. It is a tunneling protocol that can give you the illusion that two tunnel interfaces are connected together. You can then set attributes within those two tunnel interfaces as if you they are directly connected to each other (not everything, but most everything). Thus, GRE tunnels do provide multi-protocol support. In order to determine which technology would be best suited for your needs, your VPN business case should provide you with answers to the following questions: 1) Are there just two sites that need to be connected together? (i.e. are there plans for a large scale deployment?) 2) Do you need encryption? 3) Do you need authentication? 4) Do you need to protect against a replay attack? 5) Who are you protecting your data from? Cisco Encryption Technology (CET), which is frequently used with GRE tunnels, is a precursor to IPSec and has been available since IOS 11.2. While there are similarities between IPSec and CET, they do not provide the same functionality. This is why I asked the previous questions. CET can only encrypt your data streams, while IPSec can encrypt, authenticate and provide protection against a replay attack. CET does not provide for a Public Key Infrastrucutre (PKI) and thus if you had 100's of sites to connect, CET could become an administrative nightmare. On the other hand, IPSec does provide for a PKI which can ease administrative burdens, but can give you a whole different set of problems. For example, who administers the Certificate Authority server and where do they get their authority. This is important if it is an Extranet VPN. In an Intranet VPN this is not nearly as important since most Companies can inherently trust themselves (notice I said MOST not ALL ;-). CET is fairly simple to setup, especially since it only encrypts your data streams. IPSec, has a tremendous amount of flexibility and as we all know the more flexibility a technology has, the more complicated it gets. IPSec can take a while to understand all of the underlying technology, but it can give you an extremely secure environment. Personally, assuming that: 1) We want a simple Intranet VPN protecting our data crossing the public Internet 2) We aren't protecting trade secrets worth millions of dollars 3) There are no plans on increasing the number of VPN connections I would go with a GRE tunnel with CET. If any of the above criteria aren't met I would go with IPSec. HTH, AQ At 08:46 AM 11/23/00, Liwanag, Manolito wrote: I have a remote site that I want to connect to our central site that has a PIX.

Re: Dial on demand
I assume you are using ISDN and IP but no matter you can do similar for other protocols. Set the dialer idle timeout to 200 or so. Router#(config-if)dialer idle-timeout 200 Ensure you have something set to make the call for example, Router#(config)dialer-list "dialer group number" protocol ip permit If the routers are often not in use and/or you are not using a routing protocol. ie you are using a static route to talk between the routers set a routing protocol on. Router#(config)router rip You really need all of that plus your interface configs. the book Building Cisco Remote Access Networks is full of good stuff.

Re: GRE VS. IPSEc
Excellent reading ! Adam Quiggle [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Liwang, You aren't comparing apples to apples in your questions. Let me see if I can shed some light on the subject. IPSec is a VPN technology that is responsible for securing a data stream between two VPN peers. It does not provide multi-protocol support, so if you need to transport anything other than IP, you will need to use a GRE tunnel. (assuming you only connect to the outside world using IP) A GRE tunnel does not provide any security. It is a tunneling protocol that can give you the illusion that two tunnel interfaces are connected together. You can then set attributes within those two tunnel interfaces as if you they are directly connected to each other (not everything, but most everything). Thus, GRE tunnels do provide multi-protocol support. In order to determine which technology would be best suited for your needs, your VPN business case should provide you with answers to the following questions: 1) Are there just two sites that need to be connected together? (i.e. are there plans for a large scale deployment?) 2) Do you need encryption? 3) Do you need authentication? 4) Do you need to protect against a replay attack? 5) Who are you protecting your data from? Cisco Encryption Technology (CET), which is frequently used with GRE tunnels, is a precursor to IPSec and has been available since IOS 11.2. While there are similarities between IPSec and CET, they do not provide the same functionality. This is why I asked the previous questions. CET can only encrypt your data streams, while IPSec can encrypt, authenticate and provide protection against a replay attack. CET does not provide for a Public Key Infrastrucutre (PKI) and thus if you had 100's of sites to connect, CET could become an administrative nightmare. On the other hand, IPSec does provide for a PKI which can ease administrative burdens, but can give you a whole different set of problems. For example, who administers the Certificate Authority server and where do they get their authority. This is important if it is an Extranet VPN. In an Intranet VPN this is not nearly as important since most Companies can inherently trust themselves (notice I said MOST not ALL ;-). CET is fairly simple to setup, especially since it only encrypts your data streams. IPSec, has a tremendous amount of flexibility and as we all know the more flexibility a technology has, the more complicated it gets. IPSec can take a while to understand all of the underlying technology, but it can give you an extremely secure environment. Personally, assuming that: 1) We want a simple Intranet VPN protecting our data crossing the public Internet 2) We aren't protecting trade secrets worth millions of dollars 3) There are no plans on increasing the number of VPN connections I would go with a GRE tunnel with CET.

Re: re:cciebootcamp
I read it very carefully which is why I replied. And it's always easy to say let's stop this thread here when another reply doesn't suit you. You quoted my "break the law" comment as if it was wrong to do so and all I have said is that normal people in this day and age know that such activity is illegal - not just with programs/CDs but most other things you actually pay for. Your general comments about how you have done it and probably how we all have done it supports my comment on "Everybody does it so it's ok". If you have done it how can you say you're opposed to it? (at least publicly), in a debate/discussion you can't have it both ways. If your comments were aimed at the "looser" poster it would have been nice if you attached your reply to that post or at least qualified your remarks. I am very opposed to the "benefit of the doubt" idea (not your comment) as that says to me that the general techie population isn't very aware of the very basic protections afforded original work. I don't believe that is the case. Especially in this forum where just about everyone knows what products are out there and who they benefit and especially who created them. Although this is a large list, the technology we represent is a specialized niche and we all know each other (almost). Finally, if you can't stand the fire - don't jump in.

Hi, I am working towards CIPT 2.0 (Cisco Call Manager v3.0) exam. I have a CAT 6K in the core with 6608 (8 port E1 blade) as per the CIPT LABs. The problem is that the 6608 resets itself after about 40 S, making it very difficult to complete a call over the E1 link. It seems to help if I disable the unused (un-terminated) E1 ports. However, the 6608 still resets itself all be it not quite so frequently. I have tried a 2nd SUP 1A 2GE card, a different PSU and a different 6608 blade - all without success! Any ideas?

RE: IP Address Calculation [1:1010]
It's important to remember your default mask for all 3 address ranges when
looking at a question like this. A class B address has a default mask of 16
bits, so if " You have an IP address of 172.16.4.58 with a 12-bit subnet
mask." you would add an additional 12 bits to the default mask and from
there determine your valid hosts. 16 bits (default mask) + 12 bits
(additional bits) = 28 = 255.255.255.240; then 256 - 240 = 16. You will have
valid ranges in multiples of 16, 1-16, 17-32, 33-48, 49-64, etc... you do
have to remember to leave out the high and low addresses (network and
broadcast) leaving 14 valid host id's per subnet. Using a 172.16.4.58/28
notation would accomplish the same thing and is just an easier way to say "I
have a class B address with a 12 bit subnet mask". I personally struggled
with subnetting before it finally clicked, it's just important to remember
that there are only just so many combinations available. I would suggest
approaching this from multiple different angles until you find the one that
clicks for you, once it does you'll be amazed at how simple it all seems.

Hi,
It's important to understand the wording
172.16.4.58 is a Class B address. A subnet is the 'borrowed bits' from
the
host portion of the address. In this case it is stated as being 12bits
So by default it has a 16 bit network mask a Class a has 8 and a Class C
24
255 255 00
= 16Bit netmask
|---| |---|
network host
255 255 255 240
= 16bit netmask + 12bit subnet mask
+
4bit host portion
|---| |---||--|
networksubnet host
172.16.4.58 255.255.255.240 is the ip address and network mask
(anyone got a better way of explaining this bit?)
As networks must start on a border of the subnet that they are divisible
by
(anyone got a better way of explaining this bit?)
we can figure out the the network address for this IP address with this
subnet mask starts at 172.16.4.48 (this is not a host address it's a
network/cable/segment address) first available host address is 172.16.4.49
your network size is 16 IP addresses so counting from and including
172.16.4.48 you reach 172.16.4.63. The last address of the network is
discarded as being a host address as well as this will be used as the
broadcast address for the network so the available IP's assignable to
hosts
are 172.16.4.49-62
That explanation probably sounds as clear as mud but hopefully it's
helpful.
It's important to read the questions carefully for the syntax they use and
how it is applied to the subject.

RE: IP Address Calculation [1:1010]
Mitsunori:
I was looking through the Sybex CCNA Study Guide 2nd edition, and couldn't
find the question you reference--I assume it's from a different book in
their CCNA series...
I recently completed a project with Sybex that is due out in January. The
one thing my editor and I really worked on was ensuring that the terminology
used was correct and that didn't confuse the test taker. In my opinion,
when I read "12-bit subnet mask" I assume exactly that -- there are 12 bits
in the subnet mask. If I as the author of the test question wanted you to
calculate a subnet where you would tack on 12 bits of subnetting to the
subnet mask, I would use the terminology "12 bits of subnetting". Travis
was on the right track when he said that "a subnet is the 'borrowed bits'".
Those borrowed bits are "the bits of subnetting".
Often you can deduce the response being sought by looking at the options
available. In this case, the author of the question is looking for a 28 bit
subnet mask response. Same applies for whether when determining the number
of networks or hosts available, whether ip subnet zero is expected as a
response or not. For the CCNA exam, the formula to calculate hosts is
always 2^n-2 (no ip subnet zero). It's really unfortunate that a question
such as this exists, but sometimes we authors don't think about
terminology... I got caught on BRI - I thought it was Basic Rate ISDN. My
editor pointed out BRI is actually Basic Rate Interface. I checked with
CCITT (the organization responsible for ISDN standards). Sure enough, she
was correct!
As an author, I feel that it's very important for authors to think about how
someone less experienced will interpret a question. In this case, I'd say
Sybex dropped the ball - but as long as they keep the editor I worked with
on the CCNA Virtual Test Center project, I'd expect the number of errors or
unclear statements to decrease drastically. If Sybex can keep people THAT
good (and as long as my editor IS the editor), I'd definitely recommend
their future Cisco reference materials!
As you work through your CCNA, a great reference is certificationzone.com.
CertificationZone strives for an extremely high level of technical accuracy
and that really benefits the beginner because you DON'T learn things that
are wrong. Been there, done that--it's no fun. It's so hard to unlearn
things you've learned wrong... I've also heard good things about ccprep.com
(to plug someone I'm not affiliated with...) Yes, both sites charge for
their services, but you get what you pay for with Internet sites...

Subject: RE: IP Address Calculation [1:1010]
It's important to remember your default mask for all 3 address ranges when
looking at a question like this. A class B address has a default mask of 16
bits, so if " You have an IP address of 172.16.4.58 with a 12-bit subnet
mask." you would add an additional 12 bits to the default mask and from
there determine your valid hosts. 16 bits (default mask) + 12 bits
(additional bits) = 28 = 255.255.255.240; then 256 - 240 = 16. You will have
valid ranges in multiples of 16, 1-16, 17-32, 33-48, 49-64, etc... you do
have to remember to leave out the high and low addresses (network and
broadcast) leaving 14 valid host id's per subnet. Using a 172.16.4.58/28
notation would accomplish the same thing and is just an easier way to say "I
have a class B address with a 12 bit subnet mask". I personally struggled
with subnetting before it finally clicked, it's just important to remember
that there are only just so many combinations available. I would suggest
approaching this from multiple different angles until you find the one that
clicks for you, once it does you'll be amazed at how simple it all seems.

Hi,
It's important to understand the wording
172.16.4.58 is a Class B address. A subnet is the 'borrowed bits' from
the
host portion of the address. In this case it is stated as being 12bits
So by default it has a 16 bit network mask a Class a has 8 and a Class C
