CCO practice questions

[Fred Danson]

Hi,

Could anyone give me the directions to get to the practice question section 
on the Cisco website? I have CCO access, but I can't seem to find the 
questions. Also, please include directions instead of just a link, I would 
like to be able to see what else is offered in the section.

Thanks in advance,
Fred

E1 and S/T ISDN interfaces in Australia

[Albert Lu]

Hi All,

I'm trying to test an ISDN S/T interface on a 3620. At the moment, I have an
E1 link with 2 channels being used. And I was wondering if it is possible to
test the S/T interfaces on the 3620 with the E1 link? Will I fry the circuit
on the S/T port?

Thanks

Albert

Re: CID 3.0 study material/books?

[Richard Chang]

Well, I used the CiscoPress CID book and that's probably all you need to
prepare for this exam if you already had your CCNP.

Note that I would only recommend this CID books for those who want to take
the CID test. I don't think it is a good Network Design book, you should
have other reference materials so that you know how to deal all those
unclear points in the Cisco CID book.  ^__^

Re: Point-to-point vs. multi-point

[Nigel Taylor]

Thomas,
I guess the most important thing would be that in  a P-t-P
you're limited to using the
"frame-relay interface-dlci" command. Where as in the multipoint you can
make use of the "frame map" command and the interface dlci" command.  Note
that there are some pitfalls in order in which they are used.  Apart from
that there are of course various issues as it related to different routing
protocols.

Chuck L, recently posted some observations he made of the common protocols
listed on the CCIE blueprint(EIGRP, OSPF, and RIP).  Caslow's book has a
little section that covers this topic..

Re: Just picked up 2 routers

You only have 2M Ram on board, if i guess right.  No memory installed in the
DRAM Slot, if
I guess it right.

You can open the chasis of your router, you should able to insert one piece

8 RAM Flash.

RE: Did I luck out or what!

[Daniel Cotts]

If those Cisco boxes are true 4000s not 4500 or 4700s then the FastEthernet
module won't work. Your serial ports are not the standard 60 pin?? If so
you'll need to look on eBay for the correct cables - may have to do a 20'
two cable routine. You could also check out the custom cable companies.
www.stonewallcable.com or LoDanWest.com are two of many.
Verify the DRAM, shared ram and Flash on your boxes. They may need to be
increased to run newer IOS versions.
Hey - the price was right. I recently bought modules on eBay for a 4500M.
Most likely there are better deals. 4-port BRI ISDN S/T $103, 4-port serial
$425, 6-port ethernet $660.

Re: Hexadecimal numbers

[Tom Lisa]

2nd try without HTML!

Don't have a good site, but perhaps this will help.  BTW,
this assumes (and we all know how dangerous that is) that
you are fairly comfortable with binary math.  If you
aren't, I suggest you visit www.learntosubnet.com and
review their section on binary math.

Converting from Hex is quite simple if you use Binary as
your conversion medium or what I call the Nibble Method.
Since Hex is Base16 and Binary is Base2, you can think
of Hex as shorthand for Binary.  In Binary each column
position has a range of two values ( 0 or 1 ).  In Hex
each column position has a range of sixteen values (0-9
& A-F, where A=10, B=11, C=12, D=12, E=14, F=15).
Finally, in Decimal each column position has a range of
ten values (0 - 9).

>From this we can see that it takes four bit positions in
binary to represent all the possible values of one hex
position.  For example, with one binary nibble (four bits):

binary  hex  binary  hex  binary  hex  binary  hex
  =  0   0100  =  4   1000  =  8   1100  =  C
0001  =  1   0101  =  5   1001  =  9   1101  =  D
0010  =  2   0110  =  6   1010  =  A   1110  =  E
0011  =  3   0111  =  7   1011  =  B     =  F

Thus any two character HEX number (as Hex is normally
displayed) can be converted to binary simply by converting
each character separately.

HEX: A D  E7
thus
BINARY: 1010  1101  1110  0111
thus
DECIMAL:  128+32+8+4+1 = 173 & 128+64+32+4+2+1 = 231
PROOF:  16^0=1, D * 1 = 13*1 = 13
16^1=16, A * 16 = 10 * 16 = 160
160 + 13 = 173
PROOF:  16^0=1, E * 1 = 7 * 1 = 7
16^1=16, 7 * 16 = 14 * 16 = 224
224 + 7 = 231

Larger Hex numbers are also easily converted

HEX: 6B F
thus
BINARY:0110  1011  
thus
DECIMAL:  1024+512+128+32+16+8+4+2+1 = 1727
PROOF:   16^0 = 1, F * 1 = 15 * 1 = 15
 16^1 = 16, B * 16 = 11 * 16 = 176
 16^2 = 256, 6 * 256 = 1536
 1536 + 176 + 15 = 1727

Going from Decimal to Hex is just a reverse of the above
process. Convert the Decimal number to Binary, divide the
binary bits (working right to left) into Nibbles and then
convert each Nibble to Hex.

When converting Decimal to Binary I prefer the division by two method.
You divide the Decimal number by two and the remainder becomes the
first binary bit, working from right to left.

DECIMAL:   792
CONVERSION:
  792/2 = 396 Remainder 0,  BINARY = 0
  396/2 = 198 Remainder 0,  BINARY = 00
  198/2 =  99 Remainder 0,  BINARY = 000
   99/2 =  49 Remainder 1,  BINARY = 1000
   49/2 =  24 Remainder 1,  BINARY = 1 1000
   24/2 =  12 Remainder 0,  BINARY = 01 1000
   12/2 =   6 Remainder 0,  BINARY = 001 1000
6/2 =   3 Remainder 0,  BINARY = 0001 1000
3/2 =   1 Remainder 0,  BINARY = 1 0001 1000
1/2 =   0 Remainder 1,  BINARY = 0011 0001 1000
 ^^ Padded to make a nibble
BINARY:   0011  0001  1000
HEX:   3 1 8
PROOF:  16^0 = 1, 1 * 8 = 8
16^1 = 16, 16 * 1 = 16
16^2 = 256, 256 * 3 = 768
768+16+8 = 792

Another method was provided by Priscilla in a response
to a similar question by someone else.  Whichever you
use, just remember that practice is the key to
understanding.

re: 2 ISP's

[Johnny Sun]

Hi,

I want to say,without your own AS and use BGP,you cant do the load balancing
with only one router.One router only permit one interface with "ip nat
outside",this is the problem.I've do the load balancing to two isp using one
pix and two 3620 router,in which two 3620 do the job of nat.You can use
"default-network" plus dynamic routing or link the two 3620 and config
policy routing on them.

Regards.

Re: Hexadecimal numbers

[Tom Lisa]

2nd try without HTML!

Don't have a good site, but perhaps this will help.  BTW, this assumes
(and we all know how dangerous that is) that you are fairly comfortable
with binary math.  If you aren't, I suggest you visit
www.learntosubnet.com
and review their section on binary math.

Converting from Hex is quite simple if you use Binary as your conversion

medium or what I call the Nibble Method.  Since Hex is Base16 and Binary

is Base2, you can think of Hex as shorthand for Binary.  In Binary each
column position has a range of two values ( 0 or 1 ).  In Hex each
column
position has a range of sixteen values (0-9 & A-F, where A=10, B=11,
C=12, D=12, E=14, F=15).  And finally, in Decimal each column position
has a range of ten values (0 - 9).

>From this we can see that it takes four bit positions in binary to
represent
all the possible values of one hex position.  For example, with one
binary
nibble (four bits):

binaryhexbinaryhexbinaryhexbinaryhex
   =  0   0100  =  4   1000  =  8   1100  =  C
 0001  =  1   0101  =  5   1001  =  9   1101  =  D
 0010  =  2   0110  =  6   1010  =  A   1110  =  E
 0011  =  3   0111  =  7   1011  =  B     =  F

Thus any two character HEX number (as Hex is normally displayed) can be
converted to binary simply by converting each character separately.

HEX:  A   D   E7
thus
BINARY:  1010  1101   1110  0111
thus
DECIMAL:  128+32+8+4+1 = 173   128+64+32+4+2+1 = 231
PROOF:  16^0=1, D * 1 = 13*1 = 13
16^1=16, A * 16 = 10 * 16 = 160
160 + 13 = 173

Larger Hex numbers are also easily converted

HEX:  6   B   F
thus
BINARY:0110  1011  
thus
DECIMAL:  1024+512+128+32+16+8+4+2+1 = 1727
PROOF:   16^0 = 1, F * 1 = 15 * 1 = 15
16^1 = 16, B * 16 = 11 * 16 = 176
16^2 = 256, 6 * 256 = 1536
 1536 + 176 + 15 = 1727

Going from Decimal to Hex is just a reverse of the above process.
Convert the Decimal number to Binary, divide the binary bits (working
right to left) into Nibbles and then convert each Nibble to Hex.

When converting Decimal to Binary I prefer the division by two method.
You divide the Decimal number by two and the remainder becomes the
first binary bit, working from right to left.

DECIMAL:   792
CONVERSION:  792/2 = 396 Remainder 0,  BINARY =  0
 396/2 = 198 Remainder 0,  BINARY = 00
 198/2 =   99 Remainder 0,  BINARY = 000
   99/2 =   49 Remainder 1,  BINARY = 1000
   49/2 =   24 Remainder 1,  BINARY = 1 1000
   24/2 =   12 Remainder 0,  BINARY = 01 1000
   12/2 = 6 Remainder 0,  BINARY = 001 1000
 6/2 = 3 Remainder 0,  BINARY = 0001
1000
 3/2 = 1 Remainder 0,  BINARY = 1 0001
1000
 1/2 = 0 Remainder 1,  BINARY = 0011
0001 1000

^^ Padded to make a nibble
BINARY:   0011  0001  1000
HEX:   3 18
PROOF:  16^0 = 1, 1 * 8 = 8
16^1 = 16, 16 * 1 = 16
16^2 = 256, 256 * 3 = 768
 768+16+8 = 792

Another method was provided by Priscilla in a response to a similar
question by
someone else.  Whichever you use, just remember that practice is the key
to
understanding.

Re: ISDN B Chanell

[jenny . mcleod]

Try using 'debug dialer', and 'debug isdn q931' (on both routers).  Is the
router *attempting* to dial?  If so, is the call being seen by the other
router?

Re: HEX

[Tom Lisa]

As President of the OGC, I would like to add an additional point.
Your exam time limit doesn't start until you click on the button.
That means you can take all the time you want to write out all
the conversions on the scratch paper they give before you start
the test! I find trying to do these conversions extra difficult when
I'm worrying if I'll have enough time to finish the exam.

Re: Hexadecimal numbers

[Tom Lisa]

Don't have a good site,
but perhaps this will help.  BTW, this assumes
(and we all know how
dangerous that is) that you are fairly comfortable
with binary math. 
If you aren't, I suggest you visit www.learntosubnet.com
and review their section
on binary math.
Converting from Hex
is quite simple if you use Binary as your conversion
medium or what I call
the Nibble Method.  Since Hex is Base16 and Binary
is Base2, you can
think of Hex as shorthand for Binary.  In Binary each
column position has
a range of two values ( 0 or 1 ).  In Hex each column
position has a range
of sixteen values (0-9 & A-F, where A=10, B=11,
C=12, D=12, E=14,
F=15).  And finally, in Decimal each column position
has a range of ten
values (0 - 9).
From this we can see
that it takes four bit positions in binary to represent
all the possible values
of one hex position.  For example, with one binary
nibble (four 
bits):
binary   
hex    binary    hex    
binary   
hex    binary    hex
   = 
0   0100  =  
4  
1000  =  8   1100  = 
C
 0001  = 
1   0101  =  
5  
1001  =  9   1101  = 
D
 0010  = 
2   0110  =  
6  
1010  =  A   1110  = 
E
 0011  = 
3   0111  =  
7  
1011  =  B     = 
F
Thus any two character
HEX number (as Hex is normally displayed) can be
converted to binary
simply by converting each character separately.
HEX: 
A   
D  
E    7
thus
BINARY:  1010 
1101  
1110  0111
thus
DECIMAL:  128+32+8+4+1
= 173   128+64+32+4+2+1 = 231
PROOF:  16^0=1,
D * 1 = 13*1 = 13
   
16^1=16, A * 16 = 10 * 16 = 160
   
160 + 13 = 173
Larger Hex numbers
are also easily converted
HEX: 
6   B   F
thus
BINARY:   
0110  1011  
thus
DECIMAL:  
1024+512+128+32+16+8+4+2+1
= 1727
PROOF:  
16^0 = 1, F * 1 = 15 * 1 = 15
   
16^1 = 16, B * 16 = 11 * 16 = 176
   
16^2 = 256, 6 * 256 = 1536

1536 + 176 + 15 = 1727
Going from Decimal
to Hex is just a reverse of the above process.
Convert the Decimal
number to Binary, divide the binary bits (working
right to left) into
Nibbles and then convert each Nibble to Hex.
When converting Decimal
to Binary I prefer the division by two method.
You divide the Decimal
number by two and the remainder becomes the
first binary bit,
working from right to left.
DECIMAL:  
792
CONVERSION: 
792/2 = 396 Remainder 0,  BINARY =  0

396/2 = 198 Remainder 0,  BINARY = 00

198/2 =   99 Remainder 0,  BINARY = 000
  
99/2 =   49 Remainder 1,  BINARY = 1000
  
49/2 =   24 Remainder 1,  BINARY = 1 1000
  
24/2 =   12 Remainder 0, 
BINARY = 01 1000
  
12/2 = 6 Remainder 0,  BINARY = 001 1000

6/2 = 3 Remainder 0,  BINARY = 0001 1000

3/2 = 1 Remainder 0,  BINARY = 1 0001 1000

1/2 = 0 Remainder 1,  BINARY = 0011 0001 
1000

^^ Padded to make a nibble
BINARY:   0011  0001  1000
HEX:  
3 
1   
8
PROOF:  16^0 = 1, 1 * 8 = 8
   
16^1 = 16, 16 * 1 = 16
   
16^2 = 256, 256 * 3 = 768

768+16+8 = 792
Another method was provided by Priscilla in a response
to a similar question by
someone else.  Whichever you use, just remember
that practice is the key to
understanding.

RE: Doing things backwards - Question for the CCDPs in the list.

[Robert Padjen]

If you understand 'Cisco' tests taking the DCN cold
should not be too bad. The test is unlike any other,
and it will benefit you if you study books like
Priscilla's. However, CID is much harder in my opinion
regarding actual knowledge of systems, and neither
will qualify you to actually design networks. Good
luck.

Re: Did I luck out or what!

[Kenneth]

Go to Ebay and you'll find people selling network modules and WICS.

If you don't want to bother with it, there are a lot of companies that sell
used Cisco modules if you look it up the internet.

Lastly, if you want it brand new, go to CDW or shopper.cnet.com
and search for the modules there.

Re: Link problem

[Moe Tavakoli]

The Duplex issue that another person raised should fix
this for you.  Force the port to 100-full and make
sure the NIC on the other end, is fine with it too. 
You probably have a high CRC error count also.

Good luck.

Just picked up 2 routers

[vert]

I just bought 2 Cisco 2524's and I am trying to check how much ram they came
with. Can anyone inform me on how to view the memory. When I boot the router
I get this config:
cisco 2524 (68030) processor (revision J) with 1024K/1024K bytes of memory.
Processor board ID 06956739, with hardware revision 
Bridging software.
X.25 software, Version 3.0.0.
Basic Rate ISDN software, Version 1.0.
1 Ethernet/IEEE 802.3 interface(s)
2 Serial network interface(s)
1 ISDN Basic Rate interface(s)
Integrated NT1 for ISDN Basic Rate interface
5-in-1 module for Serial Interface 0
56k 4-wire CSU/DSU for Serial Interface 1
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read ONLY)

Can I figure out what the total amount of ram is from this info? I just
don't want to be cheated. I am new to the Cisco environment.

Re: How would you Explain it.

[Tony van Ree]

Hi All,

We supply quite a lot on 'LAN' connect services.  These have a Gig coming back to a 
core with a number of 100Meg ports some to various clients 'a shared connection' 
others going to a site operated by the one orgaisation.  

These come bace into a core and do so in the couple of major cores we provide this 
network.  The cores are connected using several ATM links thus providing a number of 
VLAN's statewide.  In a number of cases the 'backbone' ie the links between sites 
provides less of a bottleneck than the LAN's they connect.  This will however change 
as the LAN's are upgraded.

Typically we would have something like a 2928G.  This might provide several VLAN's 
including 'public' and 'private' address space.   These would be connected using 'BVI' 
interfaces thus allowing integrated bridging and routable networks.

This works well and is being extended to others faster than I could imagine.

My to bob's worth,

Teunis

Re: Link problem

[John Kurkjian]

Try forcing speed/duplex on the switch port and client side. I've seen this
problem when auto-negotiation doesn't work right. Try upgrading the NIC
drivers too.

dialer watch

[FERREYRA Marta]

Hello!

I have  dialer watch in a BRI interface to be backup of FR multipont
interface.

When the link goes down and the route is not in table the backup link goes
up

The problem is that the backup link go down each 121 seg and then go up
again, but the primary link is down

It is correct because there are not interesting traffic?

thanks in advance

Re: Route-map

[Vincent]

1) Check the traceroute result.
2) From your configuration, after you correct it, you may find out that you
can control outgoing traffic.
You probably can not control incoming traffic.  Generally, it is very
difficult for you to control incoming
traffic.

Re: ISDN with 1 Spid

[Craig Columbus]

Ok...since the interface won't come up, I'd say it's pretty safe to assume 
that your problem isn't SPID related.  If the SPIDs are bad, the interface 
will still come up, but you'll see an error similar to the following when 
running a "sh isdn status":

Global ISDN Switchtype = basic-5ess
ISDN BRI0 interface dsl 0, interface ISDN Switchtype = basic-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 64, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Spid Status:
TEI 64, ces = 1, state = 4(await init)
spid1 configured, no LDN, spid1 sent, spid1 NOT valid
TEI Not Assigned, ces = 2, state = 1(terminal down)
spid2 configured, no LDN, spid2 NOT sent, spid2 NOT valid
Layer 3 Status: 0 Active Layer 3 Call(s)
Activated dsl 0 CCBs = 1
CCB:callid=0x0, sapi=0, ces=1, B-chan=0, calltype = INTERNAL Total 
Allocated ISDN CCBs = 1

Since your interface won't come up, you're probably seeing a message 
similar to the following:
The current ISDN Switchtype = basic-ni1
ISDN BRI0 interface
Layer 1 Status:
DEACTIVATED
Layer 2 Status:
Layer 2 NOT Activated
Layer 3 Status:
No Active Layer 3 Call(s)
Activated dsl 0 CCBs = 0
Total Allocated ISDN CCBs = 0

If this is the case, you're experiencing a physical level problem.  Check 
your cables, verify if you're connecting with a U or S/T interface, 
etc.  You may want to have the telco do a loopback to the smartjack.
For more info, refer to http://www.cisco.com/warp/public/112/chapter17.htm

Hope this helps.

LOL.
You've been eavesdropping on some of my math sessions with my children,

you.  I've learned more about the foundations of arithmetic since I had
kids than I
did studying math in school :)

Right.
But I would assume that that doesn't mean that you are deprecating
cleverness,
per se (after all, cleverness is the Aunt of invention) but, maybe just
want to
leave cleverness where it belongs -- in the lab :)


I tend to go for the clever first and, then, after proving that it
works, start to
worry about the potential obfuscation (not to mention the phone calls)
and change to
a more "self-documenting" route.

So, one moment I might code the single ACL;
the next I would change it to the "self-documenting" two-statement ACL.

   (In fact, I would agree that you could easily argue that the second
is the more
elegant since it kills two birds with one stone:
 functionality
and no   extra documentation  :)
   )

  I've always regarded an elegant solution as one that is necessary
  and sufficient for all criteria. Maintainability is a criterion.

  A professor, in his* Tuesday class, droned on "it is obvious that
XXX
  is ZZZ."

  A student responded, "Professor, are you sure it is obvious?"

  A look of professorial alarm. "Class dismissed."

  On Thursday, the class returned to find their professor still at
the
  board, fairly obviously unwashed and unshaven since Tuesday,
perhaps
  nourished only by incessant cups of coffee.  With a tired,
triumphant,
  yet demented look, he announced: "Yes, it is obvious."

* choice of pronoun gender deliberate.  This is a guy thing**,  the
academic version of refusing to ask for directions.
** a female professor, however, might want to share the experience of
confusion.

>Cleverness :)

  There is a poorly documented corollary of Murphy's Law that
establishes
  that idiots inherit the work of the clever.

  Military organizations have much folklore about this.  In working
with
  US Navy personnel, I learned the valid distinctions between
idiot-proofing
  and sailor-proofing.  Or, as it is said, the five most dangerous
things
  in the Canadian Navy:
 -- Ordinary Seamen saying: "I learned this in Boot Camp"
 -- Petty Officers saying "Trust me, sir"
 -- Sublieutenants saying "Based on my experience"
 -- Lieutenants saying "I was just thinking"
 -- Chiefs saying "Watch this [output traffic from male cow]"

Well, can you phrase this as "full employment for consultants?"

In all fairness, there is a regrettable Cisco tendency to teach and
test for obscurity.

Re: Flash RAM erro - Cisco 2500

This sounds like incompatible or bad memory.  Your right, with the boot =

Re: How would you Explain it.

[SREY]

Kenneth,
Optical providers can be used as either an ISP or to create a MAN or WAN.
We use Yipes as an ISP, but It's not an issue.  Anybody can connect a
router, firewall, or even another switch (just use a non-routed VLAN to
seperate it from your internal network) to the ethernet port on the
provider's switch.  That is all there is to it.  The provider will advertise
your class C or even a subnetted class C.  It is up to you.  You will still
have full control over your addresses on your public subnet (except for the
gateway IP which is on the provider's equipment).  We host applications
(ASP), WWW sites, FTP sites, DNS etc.  This in no way limits my ability to
use my public IP addresses.

RE: Route-map

[Howard C. Berkowitz]

Andrew Cook gave an excellent response, to which I have some inline comments.

The whole multihoming issue is very complex.  I discuss it at some 
length in Chapter 7 of my _WAN Survival Guide_ (Wiley, ISBN 
0471384283), but as part of a broader discussion of fault tolerance 
and load distribution.  I'll get into much more detail in my next 
book on exterior routing, but that isn't available yet.\

In the meantime, RFCs 1998 and 2270 give some insight.


>Hi Jacek,
>
>If the secondary IP on FastEthernet0 is from your address space and there is
>no dynamic routing between the customer and ISP B (ISP B has no knowledge of
>your address space at the customer site), then traffic from your IP block
should NOT return via ISP B.

The situation would be handled differently if your address space was 
allocated to you directly (i.e., provider independent or PI), or if 
it was sub-assigned by one of your providers (i.e., provider assigned 
or PA).

With PI space, if you are doing this for fault tolerance as well as 
load distribution, you must:

  announce your less-specific aggregate to both ISPs
  announce the more-specific prefixes to the ISP you prefer to have
traffic to that block come into your AS

With PA space, you must:

  anounce your less-specific aggregate to both ISPs
  announce the more-specific prefixes to the ISP you prefer to have
traffic to that block come into your AS
  be sure that the assigning AS advertises your more-specific as well
as its aggregate
  be sure that the other AS coordinates with the owning AS that it can
announce a more-specific from another AS's space.
  (must in Europe, strongly recommended elsewhere) Be sure that all
three AS (you and the two ISP) register the routing policies describing
this in a public routing registry.

>
>
>If you can't/won't use BGP to solve this, I only see the following choices
>left:

To be a little more blunt,

 You can't get 100% compliance with what you appear to want even if
you use BGP.  You can, however, increase the probability it will
happen most of the time.

 In many global routing situations, saying you can't use BGP is about
as relevant as a man drowning in the ocean saying, "but the US
constitution gives me a right to life."  The ocean doesn't care.
AS with whom you have no business relationship (i.e., that collect
no money from you) are under no obligation to follow policies you
announce with BGP.  They certainly aren't going to follow policies
that they don't know about because you aren't announcing the information
about your policy in BGP, or in routing registries.

In other words, there's a reasonable mind set that comes from working 
in routing that's limited to an enterprise -- that you can control 
all flow given sufficiently powerful policy enforcement mechanisms. 
To work effectively in ISP/global routing, you have to accept that 
you are no longer in complete control, and accept that the best you 
can do is influence to some extent.

If you need tighter control than that, an interprovider VPN is the 
only alternative.  VPNs, however, require that you know all the 
endpoints before configuring.  They do not support connectivity to or 
from arbitrary Internet addresses.

I remember the behavior changing in 10-something, 10.2 to the best of 
my recollection.  That was the first release where access lists had 
significant backward compatibility problems.  The IOS, for example, 
always substituted "telnet" for "23" in TCP extended access list 
rules.

It definitely was 10.3 where the behavior of access-group changed. 
Prior to 10.3, if you defined "ip access-group 100" but there were no 
"access-list 100" lines, all traffic through the interface with the 
access group would stop.  This is quite consistent with good security 
practice, such as the Principle of Least Privilege, but was highly 
unpopular.

-

Going back to the original premise of this thread, using 
discontiguous masks to minimize the number of access list 
comparisons, writing a general program for doing so would be 
straightforward for anyone who has studied (and understood) code 
generation optimization in compilers.  While it's always hard to 
prove that something doesn't exist, I have never heard of such a tool 
in the computer-scientist-rich carrier environment.

I can think of a sort-of-reverse-case, not an optimizer but a 
code-generating program that used discontiguous masks.  When Sean 
Doran originally implemented the prefix length policy for Sprint, 
prior to the IOS supporting prefix length filters,  he wrote a 
program that generate about 16 page of access list rules.   That 
policy, incidentally, was always more complex than a simple "block 
anything longer than /19".

RE: Flash RAM erro - Cisco 2500

[Don Wahl]

This generally means the boot ROM doesn't understand the newer flash chips.
You can usually get around this by booting a newer IOS from TFTP (conf t,
boot system IOS_VERSION TFTP_SERVER,ctrl/Z, wr mem, reload) and then you can
erase the flash and copy the new IOS to it.

  I've always regarded an elegant solution as one that is necessary

  A professor, in his* Tuesday class, droned on "it is obvious that XXX
  is ZZZ."

  A student responded, "Professor, are you sure it is obvious?"

  A look of professorial alarm. "Class dismissed."

  On Thursday, the class returned to find their professor still at the
  board, fairly obviously unwashed and unshaven since Tuesday, perhaps
  nourished only by incessant cups of coffee.  With a tired, triumphant,
  yet demented look, he announced: "Yes, it is obvious."

* choice of pronoun gender deliberate.  This is a guy thing**,  the 
academic version of refusing to ask for directions.
** a female professor, however, might want to share the experience of 
confusion.

  There is a poorly documented corollary of Murphy's Law that establishes
  that idiots inherit the work of the clever.

  Military organizations have much folklore about this.  In working with
  US Navy personnel, I learned the valid distinctions between idiot-proofing
  and sailor-proofing.  Or, as it is said, the five most dangerous things
  in the Canadian Navy:
 -- Ordinary Seamen saying: "I learned this in Boot Camp"
 -- Petty Officers saying "Trust me, sir"
 -- Sublieutenants saying "Based on my experience"
 -- Lieutenants saying "I was just thinking"
 -- Chiefs saying "Watch this [output traffic from male cow]"

Well, can you phrase this as "full employment for consultants?"

RE: Route-map

[Andrew Cook]

Hi Jacek,

If the secondary IP on FastEthernet0 is from your address space and there is
no dynamic routing between the customer and ISP B (ISP B has no knowledge of
your address space at the customer site), then traffic from your IP block
should NOT return via ISP B.

If you do not meet these criteria, let me ask some questions:
1. Is the secondary IP range that you are trying to use policy-routing to
force to your ISP from your address space (or does the secondary range NAT
to one of your IPs)?  If yes, then all clients using that space should be
coming back through your link if you are the only BGP speaker announcing
that network.  If it is address space from ISP B or they are announcing the
network in addition to you, then there could be multiple routes.  It needs
to be your address space unless you do option 2 below.
2. Is this a permanent solution or are you trying to get the customer to go
with you and drop ISP B altogether?  That makes a huge difference in
configuration if redundancy/failover needs to be factored in.  I'll assume
the customer wants to keep both connections in my responses below.

If you can't/won't use BGP to solve this, I only see the following choices
left:
1. If you have no communication/relationship with ISP B -
 Customer gets addresses from both providers - default to provider B, policy
route A addresses to provider A (that's what you're trying if the secondary
is your IP).  You'll need a floating default to provider A in case the B
link goes down, and you'll need to NAT A addresses if they take the B path
and NAT B addresses if they take the A path.  That way all traffic can get
out if a link fails and all traffic can find its way back, and it will
return via whatever pipe it goes out.
2. If you have communication/relationship with ISP B -
 Both ISPs can announce the addresses delegated to the customer from the
other ISP (or you as ISP A announce the ISP B addresses and don't assign any
of your own to the customer).  You'll both have to announce the same NLRI
for the range or BGP will actually prefer the other provider for your space
(takes the most specific route).  Keep policy mapping as is, no NAT needed,
but this will not guarantee symmetrical routing for reasons Howard and
others stated earlier - you have no control over other AS routing policies.
3.  If you are using private address space (can't tell from your sample but
I didn't see NAT statements so I assume you replaced public with private
before sending), you can use a variant of either 1 or 2 - there will be NAT
going on all the time rather than for specific uses.

It sounds like 1 will be the easiest and will show the customer how your
connection performs versus the competition.  If you don't need redundancy
then you can do #1 and not worry about any NAT at all.

If you want even more answers, I suggest posting to comp.dcom.sys.cisco -
someone there can probably give you the same or better answers as I did but
in an intelligible format :)

Re: Can't get console on a Cisco WS-C1924C-A

[Brad Ellis]

Im guessing it's an older 1924?  I had a similar problem a couple years ago.
You need to get/make a different console cable.  I think it's just a
null-modem cable, but I can't be 100% certain (memory just isnt what it used
to be).  Call TAC and get the cable-pinouts.

Hope that helps.

RE: wildcard in access-list

[Bob Vance]

Let's see...
You don't care whether bit 16 (or is that 17 :?) is a 0 or a 1, right?
Then the wildcard bit can be 1 :)

A general statement would be:
If you have two otherwise identical ACL statements with
addresses that differ only in one bit position, then you
can combine the ACLs into one with the mask having that
bit position set to 1 (don't care).
You can then iterate the above for more consolidation.



>3) compare the result with the original IP address in the access-list

The actual logical compare that must be done is:

  Do the care bits of the ACL address
  match the care bits of the processed address.

(obviously :)

So, technically, the ACL address must also be ANDed with the mask
complement, in case the ACL address, as entered, doesn't have all the
don't-care bits set to 0.  Of course, this would only be done once, at
initialization, and the value stored.

IIRC, at least stating at some IOS version level, this is being done
automatically for you by IOS when it stores the ACL in the
configuration.  Thus, if you typed:

  access-list 101 tcp permit any 141.120.128.0 0.0.135.255

it would actually show up via a  'sh run'  as

  access-list 101 tcp permit any 141.120.0.0 0.0.135.255

I'm not sure about this, though --
I'm sure that someone else will confirm/debunk it.



> the comparison fails

Still correct :)

Subject: wildcard in access-list


I have two parts of a large network, the first part using 141.120.0.0
thru 141.120.7.255 and the second part using 141.120.128.0 thru
141.120.135.255. At the router connecting to Internet I want access from
outside limited only to these subnets and not to other addresses used. I
know that the following will work for TCP:

access-list 101 tcp permit any 141.120.0.0 0.0.7.255
access-list 101 tcp permit any 141.120.128.0 0.0.7.255

I want to condesnse this to a single statement as follows:

access-list 101 tcp permit any 141.120.0.0 0.0.135.255

Will this work?
For example 141.120.9.2 should not be allowed.
In binary 141.120.9.2 is 10001101.0000.1001.0010.

My understanding of the steps of how the access-list works is :

1) perform a NOT the mask, which gives in binary
  ..0000.
2) perform an AND between this and the IP address, which gives in binary
  10001101.0000.1000.
3) compare the result with the original IP address in the access-list
  the comparison fails
4) if successful, allow, otherwise drop.
  so the packet is dropped.

Is the above correct?
I don't have a lab to test this. I would appreciate any help. Thanks.

Why?

Or, to put in other terms, how would you like to find that access
list statement in an undocumented configuration you've just been
asked to troubleshoot?

A good rule of thumb:  suspect any mask octet that doesn't have
contiguous bits,
unless you are EXACTLY sure why it's being done:

   Subnet   Wildcard
   --   
  255   0
  254   1
  252   3
  248   7
  240  15
  224  31
  192  63
  128 127
0 255

image checksum error

[Rizzo Damian]

I have two 1600 series routers that I am trying to upgrade to a IPsec
feature set IOS. The problem I am experiencing is no matter version of the
feature set I try (I've tried 4 so far), after the image appears to load
successfuly from a TFTP server, the router displays the message "Image
Checksum Error" and then procedes to boot from ROM. I have enough memory,
flash shouldn't be of concern since I'm booting from a TFTP server. So what
gives? Anyone else experience this problem? Is it likely I got 4 bad images
from Cisco?  Thanks.

I have checked the cables they are perfectly alright. I added
carrier-delay of  4 sec but got no advantage.

What could be the source of the problem and can I solve it.

Re: Route-map

Hi Jacek,

Did you try the extended ping like I told you too... This will
enable you to specify a source and destination IP address before pinging..
This way you can clearly trace which interface; packets generated from a
specific subnet will traverse.

I am not a 100% sure, but i think your culprit is the default
route

Thanks,
Santosh

I'm confused now what your question is.  If it's why does the ping 
response often come in through a different path than the response 
went out of, nothing is broken -- there's no reason for it not to do 
so.

Be sure you are dealing with a real requirement rather something a
