NAT/PAT

[Ole Drews Jensen]

I've just finished the chapter in my bcran book about nat/pat, and I must
say that this was the toughest one so far.

I understand the theory, but I have a hard time really picturing it when we
start talking about overlapping ip addresses and stuff like that.

I will start looking for some NAT/PAT resources on-line at Cisco and other
sites, but if some of you know of a site that really shows a good picture
and some easy-to-read examples of a working scenario, I would greatly
appreciate it.

Thanks in advance,

Ole

CiscoPAW-DC Router Roast Saturday

[Bruce Evry]

Hello,

This is to invite all of you to our Router Roast. Special guest
this time will be Hank Leung, who just passed his CCIE lab last Week. 
He'll be talking about the experience of going through The Lab.

I will be doing a short talk on finishing the CCNP, which I
managed to complete last week while Hank was away.  (it was a good week
for our Cisco-DC group, eh?)

This Router Roast will be at Bob Lowery's new house.
6661 Mohawk Ct., Columbia, MD 
(you can get door-to-door directions from MapQuest.com)

Saturday, August 19, 2000
It will start at 10 am and end at 4 pm. 

As usual, lunch will be served, there will be lots of routers and
switches to play with, and there is no charge or fee. (It's Free...!)
(Do bring sodas and snacks and desserts if you can)

Hope to see you on Saturday!

Yours Truly - Bruce Evry

RE: ip forward-protocol vs. ip helper-address

[Kent]

Hi all,

In the following config, which was cut from the CD, 
why would we need the "ip forward-protocol" there,
I though the ip-helped address would do the job, to
forward all the broadcast to the servers, is that
right?

Thanks

Kent

"In the following example, one router is on network
191.24.1.0 and the other is on network 110.44.0.0, and
you want to permit IP broadcasts from hosts on either
network segment to reach both servers. Figure 14
illustrates how to configure the router that connects
network 110 to network 191.24.1.


Figure 14: IP Helper Addresses
 
The following example shows the configuration:

ip forward-protocol udp
!
interface ethernet 1
 ip helper-address 110.44.23.7
interface ethernet 2
 ip helper-address 191.24.1.19

Re: Default Route in BGP

[Pablo Thoma]

Or you can use the router bgp config command:

default-information originate

which does the same as 1) but for all neighbors.

Re: books on security specialization

[cryptobyte]

Sorry, text only stripped off URL pointer(s).
Ancillary material available from www.smartforce.com
for Cisco Router Firewall &
Perimeter Security; or, www.smartforce.com
for Cisco Security Solutions.
I believe it is available separately (i.e., not bundled with Internet
Security
Consortium CD).  I haven't seen it at Cisco proper.
For that matter, given Security interest, you might take a look at Internet
Security Consortium offering.  It is was $2,500 and covers pretty
near the whole
gambit; however, Check Point and RAS pulled out at last minute.
Not a dealer. Not a rep.
Good luck.

RE: 2924XL and 2600 Trunking problem

[John Neiberger]

I've discovered in my testing that the second VLAN interface will not come
up unless it is made the management interface.  If that happens, the first
VLAN interface goes down and the second comes up.  

This makes sense to me.  I placed IP addresses on both VLAN interfaces,
which is unnecessary.  On a 2924XL, only the management interface needs an
IP address, as far as I can tell.

Anyway, that problem is resolved as far as I'm concerned.

Thanks for all of the responses!

Re: CCIE review....

[Gary Frye]

1).  HDLC will count bad frames and drop them.  It's up to the hosts to
retransmit.

2).  LEC could fail to find a LECS because it isn't configured with the
LECS' VCI/VPI, and the LECS isn't operating on a well-known VCI/VPI (there
are other reasons, but that is the most prominent)

3).  The * means that this route entry is the last resort route.

4.)  No need to worry about STUN.  Cisco has all but dropped interest in it
and you won't see it on any tests (not even the CCIE written/lab).  In its
place, be sure you know the hell out of DSLSw+ and RSRB.

RE: PIX

[Darren Johnson]

Maybe I misunderstood you original question if so then you have your answer
if not...
Yes, it is a completely different box connected through the failover cable
to the primary PIX.  It should be the same version of software as if you are
running a fairly complex config you will probably have some commands not
supported on an older software version.  Also to be truly redundant, they
should be on separate power circuits, etc..
If you have any other questions let me know.

Routers for sale

[Glenn Flood]

I know that this is 
not the place to do this but I need to pay some bills.
 
I have two routers 
that I am about to put on eBay but though someone in the group could use them 
for their lab.
 
1) Cisco 4500m+ w/1 
Ethernet, 2 Token Ring and 4 Serial interfaces
1) Cisco 2611 w/4 
port A/S AIM module
 
Can be sold together 
or individually.
 
Make me an 
offer.
Thanks, Glenn

Or you can use the router bgp config command:

default-information originate

which does the same as 1) but for all neighbors.

Re: about the queuing

[Michael Fountain]

It sets the number of packets the router will hold in queue before 
discarding new packets.  Called congestive-discard.  Default is 64 packets.

Here is a like that explains it better, watch the wrap.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios112/112cg_cr/1rbook/1rsysmgt.htm#xtocid196228

When you need explanation of what a command is doing, the easiest thing to 
do is go to Cisco's web page, and do a search on the command.  ie 
"fair-queue". and you will usually come up with a couple of pages that 
explain the command fairly well.

hope that helps,
Mike

 I actually agree with his suggestion of using 3548XL's.  This

which also gives him 96 ports, assuming he uses the Gig ports for
connecting them.  For about the same as the 3548XL's, he could get the
104-port stack pack, (WS-C2900-XL-EN-104) which includes 1 2924M XL and
4 2924XL's (I don't know what the exact configuration is, lookup the
part number I gave on CCO).  I'm in Canada so I wouldn't be able to
give accurate US prices; besides, I don't generally post prices since I
don't wish to abuse this list (unlike certain others).

 The 5000 family is old, I would go with the 4000 family.  Cost may
change this, but in general I think it is better to go with newer
equipment which is going to have a longer service life.

Re: Why the route in BGP table doesn't appear in IP table.

[Arya Salahi]

As far as I know 2 things could cause this.

1: You don't have a route to the next-hop address in the BGP table.

2: Has to do with the "Synchronization" rule which states that any route 
received from IBGP speakers would have to also been learned through an IGP.  
To get around this rule you could turn off synchronization under the router 
bgp process.

Re: Vlan Error...

[Arya Salahi]

My guess would be that you have some VLANs being trunked which have not been 
configured on the router with the encapsulation isl command.  If this is the 
case, you could restrict the trunk on your switch to only allow VLANs that 
you want to route and not all VLANs which reside on your switch.

Re: Vlan Capable Router

[Arya Salahi]

In a nutshell, a VLAN capabale router is one with a FastEthernet port that 
can be configured for ISL or 802.q encapsulation which would connect to the 
trunk port of a switch.  It would then be able to receive packets from the 
switch and be able to tell to which VLAN each packet belongs to eventhough 
all packets are being received through the same physical interface.  It 
would also be needed to route between VLANs on the same switch.

Re: 2 2501's as a frame relay switch - Once and For All

[Tighe Kuykendall]

I worked through some Frame Relay scenarios last weekend and used tunnel
interfaces to switch frames between three routers on an Ethernet segment
(representing a core).  I had several PVC's up but ran into problems
when I tried
the following:

R1(s0 dte)(s0 dce)R2(tun 0)(tun 0)R3(s0 nni)(s1 nni)R2(tun
1)(tun
1)R4(s0 dce)(s0 dte)R5

You can see the loop between R2 and R3.  All of the DLCI's were unique
on each
router and everything looked like it should work, but no luck.  Although
PVC's
across these devices that didn't create a loop like this worked fine. 
If DLCI's
are locally significant, it shouldn't matter that the PVC crossed the
same router
twice.

How is RouterA suppose to know how to get to 192.68.1.1 (The return
packets)?  Do you think BGP is going to do that for you?  Try "sh ip bgp
neigh 172.16.20.1 adv" on Router B..does it show its
advertising 192.68.1.1?  Probably not.  You should add a network statment
so that it gets advertised.  Also your mask on RouterA is 255.255.255.0
for the loopback (do you really need to bind an entire /24 to
loopback)?  On routerB its just a /32...stick with /32's or
non-overlapping networks imho

Re: Why the route in BGP table doesn't appear in IP table.

[Brian]

A little confusing below, 99% right, but "no sync" causes the IGP and EGP
to not be in sync and is probably what you want in most cases, like
multihoming to multiple ISP's etc.

Re: books on security specialization

[joel.studtmann]

They have improved some.  I was just 
commenting to myself that their current release of BCMSN seemed to be bug 
free   then it crashed on one of the practical 
exercises.
 
If you're paying for them what I am (i.e., business 
has a contract, and I'm not), they're pretty good.  They're worth the time 
it takes to go through them, and finding the mistakes emphasizes the 
material.

simple question about FR/ATM (ethernet)

Ehernet uses csma-cd and hence multiple
computers(hosts)
can access and send data according csma-cd protocol.
fine...

now what about FR and ATM. they are just serial links.
right ?
ie only two computers (hosts etc) can connect across.
right ?

if the above is fine then

 across this line when one computer transmits the
other
listens and then sends... how does it work ?

Hi,
We have a 3640 router that we would like to use instead of a 7505. This 7505

controller card with 2 ports. We would like to configure this controller 
card with the existing 2 T-1's.  Is this possible to begin with??

If so, is configuring the 3640  T-1 card different from configuring the

RE: Why couldn't ping to this address?

[Gils]

It is probably because you don't have routes to the ip addresses of the
loopback interfaces and when you are pinging in a standard manner you are
pinging with the source ip address of the ethernet, when you are pinging
with extended the remote peer don't have a route back to the source ip
address.


   I hope it helps and I hope I got the full picture.

How is RouterA suppose to know how to get to 192.68.1.1 (The return
packets)?  Do you think BGP is going to do that for you?  Try "sh ip bgp
neigh 172.16.20.1 adv" on Router B..does it show its
advertising 192.68.1.1?  Probably not.  You should add a network statment
so that it gets advertised.  Also your mask on RouterA is 255.255.255.0
for the loopback (do you really need to bind an entire /24 to
loopback)?  On routerB its just a /32...stick with /32's or
non-overlapping networks imho

Re: PIX

[Ing. Francisco Quiroz Collazo]

For failover you need two pix's, with the same software (version), and the
same configuration of hardware (#, and type  of ports), and a special cable
for failover. The pin out of this cable is available in pix docummentation.

[Dale Holmes]

No.

No. Frame Relay is a layer 2 specification that is what they call NBMA, 
Non-Broadcast Multi-Access. This means that multiple connections can exist.

ATM is a connection-oriented cell-switching tecchnology where multiple 
virtual circuits, Permanent Virtual Circuits (PVC's) or Switched Virtual 
Cirtuits (SVC's), can exist.

>how does it work ?

I would recommend that you start with the Internetworking Technologies 
Handbook from Cisco Press. This will give you a good foundation and basic 
understanding of these kinds of things (as well as many others...). The book 
is relatively inexpensive and I think you will find that it provides a 
wealth of information.

Perfomance prob with Router-Router IPSEC tunnel..

[Cisco Group]

Hi 
Guyz,
 
We are having a 
cisco router-router IPSEC tunnel between two locations(Intranet VPN) over an 
internal leased line.The performance is very poor even though the link is only 
40% utilised. On examining we found that the tunnel bandwidth is only 9k..Is 
there anyway I can increase the tunnel bandwidth or can i have an IPSEC 
connection without using a tunnel so that i can use more bandwidth in the link.. 
There is a bandwidth command in the interface mode but it is only for 
calculation of cost and it has no impact on the actual tunnel 
bandwidth
 
Can anyone pls help 
me out with this...Thanx in advance..
 
Regards,
Nandu

RE: question on ip packet

[Radford Dion]

Here Here. 

It's a shame that you forgot to answer the question yourself - but I imagine
that was an oversight.

The contents of an IP packet include :

1. A quantity of small, edible 'IPs' (similar to potato chips but not quite
as tasty)
2. A non-edible plastic toy (I emphasis the words 'non-edible' - they are
definitely not tasty!!)
3. Information on where the IP packet was made
4. Information on how many 'IPs' should have been in the packet (the
difference between this value and the actual number of 'IPs' found in the
packet is proportional to the QOS, which is printed on the outside of the
packet).
5. Information on what do to if you swallow the non-edible plastic toy.

Hope that helps.

Dion

RSVP & WFQ

[Mohamed Shommo]

I have basic questions about RSVP and WFQ
1- How WFQ works ? I mean how are the number of queues
are governed when you enable WFQ ?
2- How is algorithm works ? i,e how are the packets
classified and how are the low volume data are placed
on the queue front ?
3- How does RSVP interact with WFQ ? I mean if I
reserved 50k on 128k interface how is the interface is
going to handle  the mixed traffic in terms of queues
and weights of the queues.
Your help will be highly appreciated.
4- How is packet scheduling and classification work ?
i,e How are the internal algorithm works
Thanks

We are configuring a PIX interface with the following Address/Subnet Mask.
They are 10.9.2.3/255.255.255.0

Would this be Class A address? It is using private address space. Would the
subnet mask determine the network class?

Thank you in advance.

Have a look at
http://www.cisco.com/univercd/cc/td/doc/product/software/ios111/cc111/dwfq.h
tm for a discussion of various flavors of WFQ.  

RSVP is a different animal.  RSVP is used to reserve specific resources
across a path.  

See: http://www.isi.edu/div7/rsvp/rsvp.html for a discussion of RSVP.

I'd also recommend that you get a copy of Geoff Huston & Paul Ferguson's QoS

aux vs console port, what's the difference?

[Tom Pruneau]

Greetings All knowledgeable cisco router types

I thned to use the console port for all my out of band access, but on
occcations have also used the aux port, they seem to be interchangeable

but is there a difference?
are there things you can do with a console port that you cannot with an aux?
are there things you can do with an aux that you cannot with a console?

and if they are not different why didn't cisco just call them con 0 and con 1?

RE: Class A or C??

[Taylor, Don]

The address is determined by the bit pattern in the first octet. Anything
that begins with 0 is a class A; 10 is a class B; 110 is a class C; 1110 is
a class D; 0 is a class E. Since 10 (decimal) is 1010 in binary, it
begins with 0 and is therefore a class A.

The idea of class is outdated but we still use the terminology as a kind of
verbal shorthand. In your case I would refer to it as a Class A address with
a Class C mask. It's not meant to confuse the issue, but it's easier to say
"class C" than "two fifty-five dot two fifty-five dot two fifty-five dot
zero." Knowhatahmean? =)

Remember that you have to enable "ip classless" before your address/mask
combination works correctly, so if you're not using classful addressing
anyway, the argument of class is moot.

RE: I am now CCNP 2.0

[McCallum, Robert]

Only through my own experience, but the CCDA is a complete doddle.  It only
tasks your common sense.  The hard part about it is reading the damn case
studies over and over and over again, so much so that you end up getting
peed off with them and guessing the most correct answer.  The CID (CCDP)
exam however is another matter.  As far as I am concerned this is the
hardest exam you will sit in the CCDP / CCNP qualifications.  The sections
are wide and varied i.e.

Desktop Protocols 25% worth.
Wan Design 25% worth
TCPIP design 25% worth.
SNA design around 8 questions.
Stratacom around 2 - 5 questions.
The rest is made up of piddly little areas (I cant remember exactly).  The
problem is not that the content is exactly unbelievably hard it is that you
have to approach the exam with common sense rather than technical.  Most
questions have at least 2 if not 3 correct answers BUT only 1 is the most
correct answer.  One bit of advice is to treat this exam with respect.

Hope this helps.

It appears that the BSCN part of CCNP is the only course that focuses on
BGP.  According to the course outline on Cisco's site anyway.  Can anyone
confirm that?

Dave

I think your right. The CIT course/class outline of "troubleshooting Campus 
networks" might have some in there. I wouldn't rule out having a few 
questions about BGP on the CIT exam, though.
Just my take on it,

Re: Class A or C??

[David Ristau]

it'd be a class A address with a 24 bit subnet mask
generally 10.9.2.3/24

but remember you are locking yourself into 254 hosts on the entire
network. 
A better idea might be to use a 192.x.x.x or a 172.x.x.x and a 16 bit
mask,
this'd make life easier to subnet in the future.  10.9.2.3/16 just won't
work.

the address classes are always the same. the number of bits used in the
mask tell
you how many subnets

RE: Class A or C??

[Timmons, Robert]

The terms Class A, B & C are somewhat dated.  I know Microsoft & Novell 
continue to use them, but in the Cisco world, it would be known as a
10. address with a /24 mask.  The 10. range is considered private and
I would assume it's being used on the inside with some address translation
to get to the Internet.

The address is determined by the bit pattern in the first octet. Anything
that begins with 0 is a class A; 10 is a class B; 110 is a class C; 1110 is
a class D; 0 is a class E. Since 10 (decimal) is 1010 in binary, it
begins with 0 and is therefore a class A.

The idea of class is outdated but we still use the terminology as a kind of
verbal shorthand. In your case I would refer to it as a Class A address with
a Class C mask. It's not meant to confuse the issue, but it's easier to say
"class C" than "two fifty-five dot two fifty-five dot two fifty-five dot
zero." Knowhatahmean? =)

Remember that you have to enable "ip classless" before your address/mask
combination works correctly, so if you're not using classful addressing
anyway, the argument of class is moot.

Only through my own experience, but the CCDA is a complete doddle.  It only
tasks your common sense.  The hard part about it is reading the damn case
studies over and over and over again, so much so that you end up getting
peed off with them and guessing the most correct answer.  The CID (CCDP)
exam however is another matter.  As far as I am concerned this is the
hardest exam you will sit in the CCDP / CCNP qualifications.  The sections
are wide and varied i.e.

Desktop Protocols 25% worth.
Wan Design 25% worth
TCPIP design 25% worth.
SNA design around 8 questions.
Stratacom around 2 - 5 questions.
The rest is made up of piddly little areas (I cant remember exactly).  The
problem is not that the content is exactly unbelievably hard it is that you
have to approach the exam with common sense rather than technical.  Most
questions have at least 2 if not 3 correct answers BUT only 1 is the most
correct answer.  One bit of advice is to treat this exam with respect.

Hope this helps.

Re: RSVP & WFQ

[Michael Fountain]

I'm not familiar with RSVP, can I can help with WFQ.

WFQ is enabled by default on nearly all serial interfaces with speeds less 
then 2Mbps.  (Exceptions are if you are using SDLC, X.25, LAPB, compressed 
PPP, and maybe a couple others).

WFQ is able to sense the various 'conversations' between end stations by 
identifying packets based on a couple of things -
Source/Destination network address
Source/Destination MAC address
Source/Destination port number
Frame Relay DLCIs

If queueing is necessary on a link, then packets are put into the fair 
queue.  They are serviced from the queue in order based on the time of 
arrival for the last bit of each packet.

So, even if a big FTP packet arrives into the router before a small E-Mail 
packet it is likely that the E-mail packet will get transmitted first 
because the E-mail packet finished arriving before the FTP packet.

Because they service the queue like this, smaller packets will have a 
greater chance of being transmitted first which gives them a semblance of a 
higher priority.

The router can also keep track of the 'conversations' and small packet 
conversations can have their queued packets interleaved with the packets of 
a large packet conversation like FTP.  This keeps them from being held up in 
queue too long if there is already a bunch of packets in queue for the large 
packet conversation.

The only adjustable variable for WFQ is the congestive discard.  If a 
high-volume/large-packet conversation has packets in queue, it can only have 
the number of packets up to the congestive-discard value.  Once the number 
of packets reaches that number the router no longer queues packets for that 
conversation until the number of packets in queue drops to 1/4th the 
congestive-discard value.

  I don't know about how RSVP works, but I can explain some about how 
Frame-Relay traffic shaping works in association with queues, and it may be 
pretty similar.

  With FRTS you can give each PVC a CIR & Burst speed.  If the traffic for 
that PVC goes over those amounts it needs to be queued.  After the router 
determines that it needs to be queued, it sends it to the queueing process 
in effect on that PVC (WFQ for our example).  The router then begins 
queueing and de-queueing the packets as explained above.

  I would guess if you reserved 50K of traffic on a link, and the link was 
full, and you had more then 50K of traffic to send, the remainder of the 
traffic (after the 50K) would be queued up, and then the queueing process 
would determine in which order packets were serviced until the traffic load 
dropped and the queue had been emptied.


Hope that helps some,
Mike

Try changing the baud rate on your terminal emulator until a match is found. 
  Usually this problem is caused by a router console port which has been

Re: Easier way to do Access-lists

[Dale Holmes]

What is strange about it is that I can't tell where 214.3.2.50 is in 
relation to the router interface on which this list is applied.

The first two lines allow tcp connections on ports between 6000 and 6063 
both TO and FROM host 214.3.2.50.

Which direction is this list applied, and on which interface?

Say for argument that it is an incoming list on int s0. Let's say that host 
214.3.2.50 opens a tcp connection on port 6001 to some host not on its local 
subnet. The packet will hit int s0, and be subject to the list. It matches 
line one, and so it is permitted. The intended recipient receives the 
message, and replies. Without even going into which port the reply is sent 
to, is it true that the reply will ALSO COME INTO s0? If not, then why 
permit traffic TO as well as FROM? Is host 214.3.2.50 a server that is one 
of many offering services on ports 6000 - 6063?

OR - is this list applied to multiple interfaces and for simplicity's sake 
includes entries for either direction? Hmmm...

By the way, lines 4 and 6 are identical. Maybe line 6 was intended to filter 
UDP?

Other than lines 4 and 6, this list is not redundant, but without seeing a 
drawing I have to say that depending on how many interfaces it is applied to 
and what direction(s) it is applied, I am not sure that this list does what 
the author thinks it does...

Does that help?

Dale

DHCP

Group,

I have a site connected to s DSL cloud to our main office.  The host
DSL router is connected to our Cisco Internet route which also sits on our
LAN.  I am trying to run DHCP on our LAN and have the remote clients request
an address from our local DHCP server.  The DHCP is NT 4.0, when I view DHCP
manager, I see a space with no IP addess, no name, but the MAC address for
the remote PCs.  What am I doing wrong?  I have a DHCP helper on the remote
LAN, and Cisco says there are no special configurations needed.  I was
thinking the router was not allowing the correct node type across the
network, but Cisco says the router does not block DHCP node types.  Help.

802.1Q support on a PCI Ethernet Card?

[ARTO . OLTACI]

Wouldn't it be nice if someone came out with a NIC card for a PC that would
support 802.1Q and allow you to put multiple IP addresses on one computer.
This would be so useful for testing, since one PC connected via trunk to a
switch could simulate multiple machines... you could do pings between one
ethernet subinterface to another through a test network.

If something like this (or close)  is available, please let me know... I'd
buy a dozen.

RE: Using Queing over the Internet

[Chuck Larrieu]

If I understand the question correctly, the answer is that queueing is
defined on the physical interface, not the logical or tunnel interface.

Priority queueing can allow you some refinement based on an access list.
 or other things )

Custom queueing works with protocol and interface traffic, and allows for
some granular control of amount of traffic.

There are things to be aware of with any form of queueing that you may use.
There is a good discussion on queueing at:

Re: Easier way to do Access-lists

[Roger Dellaca]

this is shorter but would deny traffice that was originally permitted - 
from hosts on 211 & 212 to 214.3.1.50 using the specified protocols & ports - assuming 
that's really what you are trying to accomplish

remember the general rule for access lists of least specific to most specific

on the 1st 6 lines though, 3 have 214.3.1.50 as source, 3 have it as destination.  
Assuming you're only going to apply the list to an interface in one direction, half of 
those lines are useless.

Also, in a production environment, you have to remember it's not how long it takes to 
type the list that's important, it's how long most packets take to find a match in the 
list that affects performance.

>>> "Kevin L. Kultgen" <[EMAIL PROTECTED]> 08/17 11:22 AM >>>
Easier way to do Access-listshow about:

access-list 111 denyip 211.0.0.0 0.255.255.255 any log 
access-list 111 denyip 212.0.0.0 0.255.255.255 any log 
access-list 111 permit ip any any 

This would still allow your 214.3.1.50 host to have it's access.  The two denies CAN 
be put togther into a single statement using:

access-list 111 denyip 207.0.0.0 7.255.255.255 any log 

but as you can see it is horribly inefficient as it will deny 207 to 215  The 
211/212 combination are in different subents for a 3.255.255.255.255 wildcard

Comment:  Looks like the 214.3.1.50 host is your SNMP Server.  Your existing ACL at 
first glance appears to be isolating this Server...  but then the bottom line hits and 
your still allowing all access Your first 6 permit statements are useless.

How to use mzmaker

[Sharad]

Hi Folks

I need some help from anyone who has used the MZMaker utility.
I downloaded the MZMaker utility and used it to compress the IOS

eg

"mzmaker c2500-jos56i-l.120-9.bin c2500-jos56i-l.120-9.mz"

After it has compressed the image, do I copy it to my router from the TFTP
server using the
"copy tftp flash" command...
Do I have to rename the ".mz" file to ".bin" before I do that.

Please let me know the steps I should take to carry out this procedure

Yes.  When the router reboots, it will load and uncompress the image.  I
don't know if the filename matters, but I used .MZ

The first time I tried it, it failed for some reason.  It's worked each time
I tried since.  The file might have been corrupted the first time, or the
compression failed or something.  Suffice to say, try it until it works.

Re: default network and default route?

Because IGRP doesn't understand that 0.0.0.0 0.0.0.0 is the default network, so
you have to use ip default-network to announce the default gateway. Other
protocols like RIP, OSPF, EIGRP all don't have to use ip default-newwork
command.
