[mpls-linux-general] some more ques reg LDP

[Anil.H <a_h...@ec...>]

Hi,

I have the following questions:-

I would like to know, how do i initialize the value of Message ID in the
LDP header and what its significance is?
Am I right in saying that Address and Label advertisement messages occur
in the Operational mode.

Thanks in advance,
Anil

[mpls-linux-general] ldp-portable compilation errors

Hi all,

I am started to play with MPLS on linux.
I am using 2.4.17 patched with mpls-linux_1_128.diff.

[mpls-linux-general] Routing over Linux

[Daniel G. C. <da...@on...>]

(First of all, sorry for my english)

Hi! I'm making a network with 3 PC's with Linux-MPLS installed over kernel
2.4.13 in Red Hat Linux 7.1, now I'm testing the network before configuring
it with 'mplsadm' and I have some questions. The PC's have 2 ethernet cards
in order to make the 'router' interfaces. I don't activate them at boottime,
I activate them with the 'ifconfig' command.

- I can't ping from one side to other side of the network, that is if I have
the following network,
1 ----- 2 ----- 3  I can ping between 2 and 3, and between 1 and 2 but I
can't ping between 1 and 3, and  I can't ping between 1 and the 2 to 3
interface too, and I can't ping between 3 and 2 to 1 interface too. (it says
that network is unreachable)

I think that I have to activate routing, but I have seen with the 'network
configuration' utility (in gnome system menu) that it is activated in PC
number 2 but it doesn't work. Have I activated routing properly? Where can I
check if routing is activated? and if I don`t have activated it, how can I
activate routing properly?

- When I am configuring the ethernet cards (IP address, netmask,
gateways,...) to make a normal network, I have to put IP addresses that
belong to different networks (for the cards of a particular PC), this is
10.1.0.0 /16 (eth0)--- PC ---(eth1) 10.2.0.0 /16    but in a MPLS network
there isn't routers, they are all switches, so I suppose that all the
interfaces in a MPLS network (one MPLS domain) will have IP addresses that
belong to the same network. Is this correct?, or
Do I have to put the cards' addresses in the same way as if they were normal
routers (different net address) when I make the MPLS network?

Can someone help me? Best regards

Dani

[mpls-linux-general] Problems with MPLS 128, kernel crash

[<pim...@in...>]

Hi James,

I am able to crash the kernel (2.4.17+MPLS128+(ftos&dscp) patches from
iptables-1.2.6a) if debugging is off.

Attached is the script that sets up the DS tree.

cat /proc/net/mpls* (only relevant bits)

T21650/1        0x00000003

traffic is mapped on T21650/1 via iptables (default gateway on table 2)

I want to stress the fact that I am only able to reproduce it when
debugging is off.
Let me know if you need additional information/want me to test
something.

Re: [mpls-linux-general] increasing mtu on ethernet interfaces?

[James R. L. <jl...@mi...>]

Unless you use a card that supports jumbo frames, you will subtract the
label shim size from the L3 protocols MTU.

It's a freshly installed slackware 8 with kernel 2.4.12.

Any suggestions would be most appreciated.

Also, is there a working tar version of the zebra port?

[mpls-linux-general] iptables

[William C. <wc...@go...>]

I've followed the mini-how-to guide that is in the archive.
for linux 2.4.17 and mpls-linux 1.128.   Everything
works fine but when i try and use the iptables command.
I get this error


[root@inigo utils]# iptables -A OUTPUT -d 10.10.3.230/32 -j MPLS --set-key
0x00000002
modprobe: Can't locate module ip_tables
iptables v1.2.4: can't initialize iptables table `filter': Table does not
exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

any ideas.

[mpls-linux-general] Can MPLS-linux run on a PC?

[<wyz...@ya...>]

Hi,All
  I have read the codes of mpls-linux-1.0,Can I use it
on a common PC,whose OS platform is linux-2.4.
  With ethereal,I saw the packets all have MPLS
header,but I want to know----Just in this PC,with the
mpls-linux-1.0,can it change to a LSR?
   If so,then where it does the label switch?As you
do,through the operation of Skb_buff,label can be
add/del the IP packet.But I can not find where the
switch happened.
   I am sorry for my stupid question,but I want your
help---after add the label,the IP packet will be
forward to where to continue its process?

  Thanks in advance

Best Regard 

ZHang

Well, nothing in the world is free. So the advantages of MPLS do come at
some cost, viz. Control overhead etc.

I am afraid MPLS is not supposed to replace IP and ATM, It is intended at
a healthy marriage between these two network layer technologies. But its
still in very early stages (shd I say so?) of deployment.

Please read Rekhtar's or Eric Gray's book on MPLS to give u a better idea
of how MPLS evolved.

  I have read several documents about MPLS,and I have

  1. Does MPLS have some shortcomings?Almost in all of

Re: [mpls-linux-general] kernel compile error

[James R. L. <jl...@mi...>]

I don;t have the kernel config dependecies working correctly in the
MPLS code.  You need to turn on:

  Networking options  --->
    QoS and/or fair queueing  --->
      [*] QoS and/or fair queueing
      [*]   Packet classifier API
      <*>     TC index classifier

I hope to have this dependency resolved in the next release.

hi jim,
i am using the latest ldp from CVS..

   -------                        ------------
   |router 1|                    |  router3 |
    --------                     ----------
    eth0 7.2\                      /  9.3 eth0
             \                    /
              \           eth1   /
     eth0 7.3   ---------  9.2  /
               |router 2 |-----
                ---------
all ip 192.168.*
configuration
router 1
----------
mplsadm -L eth0:0
add respective routes m/c can ping each other
./ldp_linux
add global 192.168.7.2
add interface eth0

router 2
----------
mplsadm -L eth0:0
mplsadm -L eth1:0
add respective routes m/c can ping each other
./ldp_linux
add global 192.168.7.3
add interface eth0
add interface eth1

router 3
-----------
mplsadm -L eth0:0
add respective routes m/c can ping each other
./ldp_linux
add global 192.168.9.3
add interface eth0

but after that entries for router1 is not there in router3 but 
entry for router2 is there. also after quitting from ldp_linux 
entries from router3 are all gone and also some entries of 
router2.
sometimes my machine hang up if i quit from one of the machine in 
the network.

i have one more query is it neccessary to give diffrent ip address 
to all the ethernets in a single pc to get ldp working..

thanx in advace

Hmmm. Did you try looking at the makefile and see if there are and
directories you need to set?  Is this on a RedHat (or a derivative)
machine?  What glibc do you have?

Hmmm.  Check your MAC addresses, check your IP addresses, then
make sure ARP is doing the right thing by running tcpdump.

Re: [mpls-linux-general] will this work?

[James R. L. <jl...@mi...>]

What you want is a Layer 2 Cross Connect (ietf draft-martini).

For this to work you need MPLS LSPs that traverse from endpoint to
endpoint (across the 'internet' in your drawing).  Then you run an indirect
LDP session from end to end that can exchange 'L2T FECs'.

mpls-linux has the forwarding code to make this happen, ldp-portable
doesn't have the signalling code (yet).

[mpls-linux-general] will this work?

[Hotlinks I. S. <pa...@ho...>]

Dear Group,

I'd like to introduce myself, My name is Panny Malialis and I run an ISP based in London UK.
HELLO :)

I put a diagram in order to help explain my goal below,

Actual connectivity
<switch 1>---(eth1-router1-eth0)---{internet}---(eth0-router2-eth1)---<switch 2>

Logical Connectivity
<switch 1>-------------------------------------------------------------<switch 2>

What I want to achieve is for <switch 1> to see <switch 2> as if there was a really long ethernet cable there.

From what I've read so far mpls is the way to go, am I correct?

Many Thanks

[mpls-linux-general] Problems with ethernet cards

[Daniel G. C. <da...@on...>]

Hi!I'm making a network with some Pcs with MPLS-Linux installed over
Red Hat 7.1.
Now, I'm connecting the PCs directly with cross-connect cables and I
have some problems.
I am trying to connect 3 Pcs in this way 1--2--3, the first PC have a
Realtek and
a 3Com card but I use the Realtek to connect to the second PC, the second PC
have
two ethernet cards, one Realtek RTL 8139(A) and one 3Com 3c509 Tornado
series, and the third PC have two 3Com cards and a Realtek one
but I use one of the 3Com cards to connect to the second PC.

This is:

1 (Realtek) <--> (Realtek) 2 (3Com) <--> (3Com) 3

Before I try to use mplsadm to configure the MPLS network, I am trying
to test the connections making ping between them, but when I try it,
it only work in one way, for example between 2 and 3 or between 1 and
2. And when I deactivate the card that seems that doesn't work in 2,
and then when I reactivate it, it begins to work in the other way but it
doesn't work in the first way that was working before.

It is:

   if the Realtek cards work in 2 <--> 1
       I deactivate the Realtek (in 2) that works 2 <--> 1
       I reactivate it
       now, the 3Com works in 2 <--> 3
       but the Realtek doesn't works in 2 <--> 1

   else
        if the 3Com cards work in 2 <--> 3
           I deactivate the 3Com (in 2) that works 2 <--> 3
           I reactivate it
           now, the Realtek works in 2 <--> 1
           but the 3Com doesn't works in 2 <--> 3

(To activate and deactivate the cards I use the ifconfig command or
the 'network configuration' utilitie that is in the 'System' menu on
Gnome X-window system)
(I am using IP addresses that belongs to the same network for all the
cards, but I don't think this is a problem because I am doing a ping between
two PCs that are directly connected.)

I don't know what it happens, if somebody have seen it before and
know how to fix it, please help me!

And I don't know if it would make problems when I try to configure
the MPLS network with mplsadm, I supose that if I can't ping in one
way, MPLS wouldn't work in this way. Please, help me I don't know what to do
so I
would be very pleased if someone can help me.

Best regards.

Dani

You are correct.  This doesn't mean that ldp-portable doesn't know how to
distribute new labels, it is just that the ldp_linux porting layer doesn'=
t
listen to route changes from the kernel.

[mpls-linux-general] ldp dynamic ??

[Kanwar D. S. <kan...@ya...>]

hi jim,
  i am using latest ldp from CVS. is that ldp dynamic
i mean if i add a new route while ldp is running ..
does it going to distribute labels for it or it just
uses the route which r there in /proc/net/route at the
start of ldp_linux ..

[mpls-linux-general] processing delay of MPLS packet

[yu-xiao j. <yx...@ho...>]

Hi all,

We set up the mpls for linux testbed as followed:

host --Ingress---Core---Egress --host

mpls work fine, we can monitor in ethereal. we want to calculate the 
processing delay on the core router.

For Ip packet, we can use tcpdump to calculate the difference of arriving 
and departure time for each packet.

Now for mpls packet, tcpdump can not catch. our question are:

1. can  ethereal be used to calculate delay?
2. is there any patch for tcpdump to make it see mpls packet?
3. is there any other tools to calculate the mpls packet delay?

thanks in advance

[mpls-linux-general] Problems with iptables

[Zeljan S. <zs...@pi...>]

Help needed,

Background:
Debian Linux. Kernel 2.4.17 patched to support MPLS. Got MPLS patch =
version 1.2.128.
(think it's the newest patch...got it with CVS)
Also patched iptables-1.2.4 with iptables-1.2.4-mpls patch (also got it =
with CVS).

Problem:

While compiling iptables-1.2.4 problems occur. This is what happens :
In file included from libipulog/libipulog.c:19:
/usr/src/linux/include/net/if.h:89: field fru_addr' has incomplete type
/usr/src/linux/include/net/if.h:90: field fru_dstaddr' has incomplete =
type
/usr/src/linux/include/net/if.h:91: field fru_broadaddr' has incomplete =
type
/usr/src/linux/include/net/if.h:92: field fru_netmask' has incomplete =
type
/usr/src/linux/include/net/if.h:93: field fru_hwaddr' has incomplete =
type
make: *** [libipulog/libipulog.o] Error 1

I would be very grateful if anyone could tell me what the problem is and =
if
there is some kind a solution to it (there probably is but I just can't =
see
it :)).

Thanks in advance.

Zeljan
