VOipVoFR [7:34947]

2002-02-09 Thread landcai

Hi, Gang,
 I have a small thing I am still clear about, even though I thought it over.
what's the difference between VOip over frame Relay and VoFR? Does it mean
that for Voip the voice is taken as the data regarded as  layer 4 data, then
encapsulated in layer 3 ip,then further be encapsulated as layer 2 frame
relay frames.  but for VoFR, the voice don't need to be encapsulated by
layer 3 protocol, and directly passed to layer 2 frame Relay network?
 could you shed me light over it? I could not turn it over on my brain. Many
thanks,

Re: MPLS and VPN Architectures book [7:34792]

2002-02-09 Thread Shahid Muhammad Shafi

Advanced MPLS Design book surprises me with the intro
on MPLS. Most of the ideas are exactly worded with
slight modification from Davie's book. The author
seems to have no personnel opinion at all .

TE's good intro is in Davie's book and Eric Gray also
throw some light on it. Also consider reading white
papers at Juniper and Riverstone websites.

For MPLS QoS, consider Zhang's book on QoS.

Thanks,
Shahid

Re: ip unnumbered [7:34936]

2002-02-09 Thread Gaz

Not sure what you're asking there?

The address you're going to is within your Ethernet subnet. Traceroute
shouldn't take too long (no hops).
I take it you mean this is the remote router.

I take it you made that config up (typos and all  :-) ). Paste the real
thing for both ends.
What does traceroute report?

Cheers,

  Hi All,
  I took the Cisco PIX CSPFA exam yesterday and I was
  suprised to find out that my score is 970/1000.  I've
  never worked with any type of firewalls let alone PIX
  Firewall.  I read the CSPFA book and borrowed the
  materials from a friend of mine who went to global
  knowledge training a few weeks earlier.  I am very
  disappointed with the exam.  I don't think anyone like
 
  myself should be able to pass the exam that easily.
 
  I thought yesterday's test score was a fluke so this
  morning I went and took the MCNS exam and I got a
  score
  of 960/1000.  I was completely shocked.  A few hours,
  I
  decide to sign up for the CCIE written exam.
  Amazingly
  I passed with a score of 92/100  That is unbelievable.
  To pass the exam for someone like myself really
  de-value the prestige of Cisco Certification by some
  bookworms like me.  Cisco, after all, should make the
  exam a lot harder than the way it is now.
 
  Anyone care to comment on this.

You MUST keep the fans in use, or it may destroy the equipment.

Several other cooling tips:

If it's a modular router or switch, and has any empty slots, be 
sure to cover the empty slots with blank panels. Not doing so can 
interfere with the cooling air flow inside the box.  Picture the fan 
on the left side, the next-to-the-right slot empty, and the right 
slot with a card in it.  If you left the empty slot uncovered, the 
cooling air might rush out it and not reach the right card.

There may be specific product recommendations on cooling. Offhand, 
the only one I can think of is if you put a FDDI card into the old 
4000 router, it had to go into the middle slot for cooling reasons.

If the routers have cooling air entries or exits on the side, 
preferably stack them vertically. If you have to put them on a table, 
leave a foot or so between them.  Otherwise, there is danger that the 
hot air from one will be sucked into the cool air inlet of the next 
in line, and so forth.  I've seen a bunch of 2500s fail because they 
were pushed agains each other on a table.

Re: MPLS and VPN Architectures book [7:34792]

2002-02-09 Thread nrf

The latest JunOS IJNR (Intro to Juniper Networks Routers) material  give a
better overview of basic MPLS than any of the Ciscopress books.  For a
really really really good understanding of TE, check out the JunOS Advanced
MPLS course stuff.  For a strong in-depth discussion of all manners of MPLS
VPN's, check out the JunOS Advanced VPN's materials.

However, if you want to study this stuff, I would advise you to wait until
Juniper updates its training materials.  JunOS 5.2 just came out, with a
bevy of kickass MPLS features, and you should wait until the courses have
been updated to include these features.  For example, Martini-draft L2VPN's
have just been implemented in JunOS.  What is ironic is that IOS can also do
Martini VPN's (on the 6500/7600) but there is nary a mention of it anywhere
on the Cisco website besides stupid marketing papers.

Good points all.  I'd also add the ability to continue it onto your LAN.  
Once you have LAN-connected telephones, intelligent use of DHCP

absolutely. you want something in either the 700-799 range or 1100-1199
range. see router output below:I've never actually implemented one of these
in real or lab. the choices seem to be permit or deny. There does not appear

Re: IPSec tunnels [7:34742]

2002-02-09 Thread JEK

Patrick,

What you can also do, is when your within the PIX you can issue the command
show crypto ipsec sa.  What you're looking for is the Outbound/Inbound
SPI's
(Security Parameters Index) this is a 32bit number that is negotiated
between the
peers during the IPSec SA negotiation.  There are 2 SA's for each IPSec peer
per IP Subnet and they are uni-directional (inbound/outbound).  What you
should
see is on the PIX side your outbound SPI will be equal to the inbound on the
Concentrator side  then on the PIX inbound SPI will be equal to the
outbound
on the Concentrator side.  If these are equal, then you can look at the
IPSec SA
counters with the same command (show crypto ipsec sa) and look at the
traffic
counters, and you should see the enciphering and the deciphering of data on
both
sides.  Such as, use ping with a set packet count and verify on both sides
that the
enciphering/deciphering of data is happening between the 2 peers.  Check
those
out and give us an update.  HTH.  Thanks,

   - jek

 Hi All

 I'm looking for some information on how to verify the configuration of a
PIX
 with an IPsec tunnel to a VPN concentrator. I have a tunnel that keeps
 bouncing, I think that instabilities across the internet could be causing
 some of the problems as I see the path changing quite a lot from the
 Netherlands to Dubai. I can't find the command(s), or understand the ones
 I've used, which tells me whether the tunnel is up on the PIX, I can see
 from the concentrator that it's down but I want to know about the PIX too.
 Any other advise is appreciated

 Cheers

Re: Block this MAC address! [7:34953]

2002-02-09 Thread Brian Dennis

If memory serves me correct, on a router, the MAC address access-list will 
not work for a protocol if you're routing that protocol. It's used for 
bridged traffic. If you're routing IP and need to filter based on a MAC 
address you might try looking into using a BVI.

Another easier solution would be to just allow from the customer only the IP 
addresses that are assigned to the customer.

Re: Router Fan [7:34952]

2002-02-09 Thread Gaz

I stumbled across the blanking plates for the WIC slots on the Cisco price
list the other day.
Believe it or not, they are 36 quid (50 dollars). Ridiculous price and
that's for the small ones.
I've got a few knocking around that I wouldn't be cheeky enough to charge
for, but I'm in UK, I take it you are in US Craig.
If someone has them locally it may be easier, but if you're desperate, where
there's a will there's a way.

 You MUST keep the fans in use, or it may destroy the equipment.
 
 Several other cooling tips:
 
  If it's a modular router or switch, and has any empty slots, be
 sure to cover the empty slots with blank panels. Not doing so can
 interfere with the cooling air flow inside the box.  Picture the fan
 on the left side, the next-to-the-right slot empty, and the right
 slot with a card in it.  If you left the empty slot uncovered, the
 cooling air might rush out it and not reach the right card.
 
  There may be specific product recommendations on cooling. Offhand,
 the only one I can think of is if you put a FDDI card into the old
 4000 router, it had to go into the middle slot for cooling reasons.
 
  If the routers have cooling air entries or exits on the side,
 preferably stack them vertically. If you have to put them on a table,
 leave a foot or so between them.  Otherwise, there is danger that the
 hot air from one will be sucked into the cool air inlet of the next
 in line, and so forth.  I've seen a bunch of 2500s fail because they
 were pushed agains each other on a table.

Re: Rommon mode Upload in 2509 [7:34958]

You should be able to do:

o/r 0x2101   (return)
then
i  (return)

This should reboot your router and get you to the Router(boot) prompt

From there you should be able to do a normal COPY TFTP FLASH once you've

If not come back to us.

Trunking multiple subnets on the same vlan /port [7:34975]

2002-02-09 Thread McHugh Randy

I have 15 different subnets on a eth 0/0 on a 2621 router with 15 secondary
addresses . I want to know if it is possible to change them to subinterfaces
and trunk more than one subnet accross a 2924 switch and pust more than one
subnet in the same vlan/port. That means putting more than one subnet on one
port in the same vlan. The subnets could be contiguous.

For instance:
ip address 64.41.x.241 255.255.255.248 secondary

ip address 64.41.x.249 255.255.255.248 secondary

Or most are discontiguous.

I did not think it could be done but just wanted to throw it out there to
see if anyone had a solution.
Thanks,
randy

How do you expect us to know why it's happening? Sorry, if that sounds 
harsh, but seriously, how could we possibly answer a question about how 
your network to your customer is being used?

A couple things do stick out though. The output rate is actually 192 Kbps, 
so you must have more than 128 Kbps. It appears that you actually have 512 
Kbps from the BW statistic in the show int output.

Also, 192 Kbps isn't much. Why does that concern you? Maybe your customer 
is accessing your Web site. It's no big deal. Also, to really understand 
network utilization, you have to look at it over a longer term. Is it 
constantly at 192 Kbps or was that a one-time blip?

This is the int as u seeing clearly 47000 is incoming from customer and

Re: HSRP on MSFCs with DECnet [7:34828]

2002-02-09 Thread Priscilla Oppenheimer

Sorry. It's not an answer. ;-) I was wondering if you found an answer to 
this interesting quesiton, however. There may be no other solution than to 
use the BIA and rely on gratuitous ARP? (Well, you could get rid of DECnet 
or try to isolate it to a pocket of the network. That could be a bit 
drastic, though. You probably have some important applications that use it.)

Hi,

I'm working with the following scenario.


 msfc1 msfc2
 ip -10.1.1.1  ip 10.1.1.2
 DECnet - 1.1  DECnet 1.2
 |   HSRP - 10.1.1.3 |
 |   |
-
   |   |
IP hosts DECnet hosts

I'm putting together a design using 2 6509s each with MSFCs. I want to
provide IP redundancy via HSRP, but also run DECnet on both VLAN interfaces.
The virtual MAC address problem of HSRP interacting with DECnet can be
solved using 'standby use-bia' command. However I would prefer not to rely
on the 'gratuitous arp' solution for my IP hosts; I dont know if they are
all compliant.

A better solution for a normal router is to use sub interfaces and the scope
command, say a 2620. That way, I could configure IP on one sub-interface,
and DECnet on another sub-interface. This would mean DECnet hosts could talk
happily to their DR using the DEC aa-00-04-00-xx-xx MAC address, while the
IP hosts could talk to the Cisco OUI virtual mac address - ie HSRP would
only be configured on one of the subinterfaces

eg:

int fa0.1
ip addr 10.1.1.1 255.255.255.0
standby 1 ip 10.1.1.3 pre

int fa0.2
decnet cost 10

But I dont see how I can do this trick with an MSFC. You cant split a VLAN
interface into sub-interfaces.

So how do I make a VLAN interface talk DECnet with aa-00-04 MAC address, and
also respond to the normal HSRP cisco MAC address.

Any ideas ? I really dont want to rely on gratuitous ARP. I'm sure that
anything you can do with a 2620, you should be able to to at least as good
with 6500s and MSFC !!

Thanks in advance

Mark

RE: Trunking multiple subnets on the same vlan /port [7:34975]

Try putting one subnet on each subinterface - each in turn will map to a
vlan. Trunk all the vlans to the switch. On the interfaces where you want
multiple vlans try configuring switchport multi vlan {ADD vlan-list |
REMOVE vlan-list} Valid IDs are from 1 to 1001. Separate nonconsecutive VLAN
IDs with a comma and no spaces; use a hyphen to designate a range of IDs. Do
not enter leading zeros.

 I have 15 different subnets on a eth 0/0 on a 2621 router 
 with 15 secondary
 addresses . I want to know if it is possible to change them 
 to subinterfaces
 and trunk more than one subnet accross a 2924 switch and pust 
 more than one

 one subnet on one
 port in the same vlan. The subnets could be contiguous.
 
 For instance:

 ip address 64.41.x.249 255.255.255.248 secondary
 
 Or most are discontiguous.

Re: hiding an computer ( ip address ) using acces [7:34992]

2002-02-09 Thread Ozzie Sutcliffe

Are you trying to limit remote access from outside the network or  from
within the network (LAN)
From outside the network you can use an access list but the best way would
be to use the security policy on your OS. AKA  password   etc
If you are using win 9xx without a 3rd party app your kinda hosed.
Ditto for physical security also unless you disable the floppy and CDrom.
As Howard would say 
What problem are you trying to solve..

There is a way to hide the IP by having a oneway patch cable but that only
lets the machine recieve but not transmit and because it does not transmit
nothing no arps etc and no other device can see it ..
But also because it's mute it cannot announce itself either therefore it
cannot use any networks services etc. it can just listen only
kinda like taking the number off your house, no one knows where you are ,you
can't get a phome installed or any mail delivered as you have no address..

So collisons are head on wrecks and if  serial could have  a wreck it would
be just a rear end deal .. LOL I bit at one time

Re the cable stuff
The Media Access Control mechanism is normally implemented in hardware or in
a combination of hardware and software. The primary purpose of the MAC is to
share the media in a reasonable way. Both the CMTS and the Cable Modem
implements protocols to do

Ranging to compensate for different cable losses. It is essential that the
upstream bursts from all Cable Modems are received in the Head-End at the
same level. If two Cable Modems transmit at the same time, but one is much
weaker than the other one, the CMTS will only hear the strong signal and
assume everything is okay. If the two signals are same strength, the signal
will garble and the CMTS will know a collision occurred.

Ranging to compensate for the different cable delays. The size of a CATV
network calls for fairly large delays in the millisecond range.

Assigns frequencies etc. to the Cable Modems. The Cable Modem first listens
to the downstream to collect information about where and how to answer. The
it signs on to the system using the assigned upstream frequency etc.

Allocate the time-slots for the upstream.

It is impossible to give more detailed information about the MAC, without
going into the specific standards. This is one of the areas that are most
closely tied to the specific standard.

Why do some TFTP sessions take a lot longer [7:35006]

2002-02-09 Thread Ozzie Sutcliffe

When I do the TFTP lab in class..
I have 6 routers 6 PC  and 6 Xover cables
All have the same configs except for IP addy's
Yet when the class pulls down the IOS the times for a 7 meg bin file vary
from 4 to 15 minutes.
The cables are all the same length same company who made them.
The routers are all 1601's the pc's and NIC's the same all running windoze
98 SE.
Ideas anyone ??
This week I will sniff each PC  and see what that bring up .


Ideas anyone ??


I will post the results next saturday

RE: LAN IP address [7:34934]

2002-02-09 Thread Ozzie Sutcliffe

do
debug ip arp
clear arp
make sure you set the scroll buffer on your terminal client to about 8 
times the amount of hosts .
this will tell you all the hosts the router can see and you can watch all
the
where ARP thou's  do there thing..
Not pretty tho on a busy segment on a production router and be consoled in..

RE: hiding an computer ( ip address ) using access list [7:35008]

2002-02-09 Thread William Pearch

Chiming in on the machine based filtering - 

Windows 2K and XP have an IPSec filter that you can configure to drop,
permit or negotiate security based on IP, DNS, ect.  With a little
creativity, you can configure the box so it can talk to the rest of the
world, but the rest of the world can't initiate conversation with it.
And - for your blessed few that are permitted to initiate traffic to the
'secret box' you can use certificates or preshared keys to negotiate
security and allow communication. There are a few things that can't be
secured with IPSec - IKE for example - but unless your goal is to
completely hide the machine IPSec filters should do the trick.  Frankly,
I think IPSec in W2K rocks, but that's just me.

And a nice host based IDS from Cisco, of course.  ;)

Yes, you could 'hide' the machine based on IP address and access lists,
but this is (in my opinion) a very poor and not very secure design.

Beth,

My choice would be filtering on the machine.  If you're using UNIX,
there are several IP filtering (and free) products.  You could also
tailor the routing table in the machine to only allow it to find your
other machine. 
Why tax the router?

I am adding a computer to my network that i do not want accessible via
network to anyone but myself. Can someone suggest best ways to do this,
is this possible on the router level via access list?

RE: Swithing modes [7:34993]

2002-02-09 Thread Ozzie Sutcliffe

Ath the fatkid thays
Swithing modes but without the lisp...heh
Go to www.fatkid.com
Autonomous switching is used in larger multi-slot routers. Autonomous
switching allows the switch blade or module to perform local fast switching
without placing the packet on the backplane unless it is necessary to do so.

Silicon switching uses ASICs, (Application Specific Integrated Circuits) to
perform the switching function. This allows for many operations to be
completed in a single clock cylce so performance is very fast.  ASICs can be
limiting however, since if there are too many instructions burned ontot the
chip adding functionality later can be impossbile without replacing the chips.
