[mpls-linux-general] LDP_ZEBRA problems

[Yves J. <yv...@no...>]

James,

I am facing 3 issues:

ISSUE #1:
=============================

I tried the ldp_zebra port and the application core dumps when I configure
mpls ip at the router level (CLI) like the examples where showing.

CLI VIEW:
---------------
ldpd# config t
ldpd(config)# mpls ip
Connection closed by foreign host.

Re: [mpls-linux-general] mpls-linux-0.990 setup problems

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

Are you trying to do ingress filtering based on bandwidth or are you
just tring to do a basic ingress LER <-> LSR <-> egress LER?

If you tring to ingress filter based on bandwidth then README.ingress
is the correct place to start.  If your just trying to build a simple
LER/LSR/LER example utils/README.example is the one you want to look at.

I haven't tried ingress filtering in a long time.  Could one of the original
users of it verify that it still works?

[mpls-linux-general] mpls-linux-0.990 setup problems

[jk s. <jk...@us...>]

hi all,
I have downloaded mpls on linux ( mpls-linux-0.990 ) from
www.sourceforge.net.
I have configured the mpls setup as given in README.ingress file.
What I did is configured 2 tcp nodes , 2 LERs and 1 LSR. I used two ether=
net
cards on each of LSR and LER.
My linux kernel 2.4.3 also detects all these ethernet cards.

My problem is that when I run the script on each of this nodes according =
to
README.ingress file running some application like PING or ftp to the end =
node
Host B it gives an error message that =

" Destination address unreachable"from (LER A ip node ).

I hope if any of U tried this package can help me accordingly.
My requirement is to demonstrate MPLS label switching with a small setup
if any of U have alternate solutions let me know.

Cheers ! !

[mpls-linux-general] Version 0.992 is out

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

I just release mpls-linux 0.992 to the SF files area.  Due to lack of sleep
the file is called mpls-linux-1.0pl2.tar.gz.  Don't worry it is version 0.992
with a too optimistic of a name :-)

Check the relase notes for info about what has changed.

http://sourceforge.net/projects/mpls-linux/

As always let me know what breaks :-)

[mpls-linux-general] Problems in compiling ldp under RH

[Roberto M. (ERI) <Rob...@er...>]

Hello all,

I have a little problem in the compilation of the latest version of the ldp-portable source code. If I try to compile it under Mandrake 8.0 it works fine, but unfortunately I'm not able to compile it either under RH 7.0 or RH 7.1. Has anyone experienced such problems? Any hint or suggestion will be greatly appreciated... thank you!

[mpls-linux-general] mpls on 2.4.5

[nomit k. <nom...@in...>]

Hello

sorry fot the duplicate message

I have the version 2.4.5 of Linux kernel. How can I enable MPLS support
on it.
I tried using the mpls-2.4.0-test11.diff patch on this but it did not
work completely on this version ( Is there a different patch for 2.4.5
kernel ). I do not get Multi-protocol label switching option by doing
make menuconfig.



Any pointers what to do.

TIA

[mpls-linux-general] BUG FIX: mplsadm+ingress policing

[Elio F. <el...@ti...>]

The network is:

HOST_A      LER_A                     LER_B             HOST_B
    |   10.0.1.    |         |  131.114.33.  |   |  192.168.4.   |
   ---------------       ----------------       ------------------
     .2             .1     .172             .200    .2                   .1

On LER_A
$TC qdisc add dev $INDEV handle ffff: ingress

mplsadm -L eth0:0

mplsadm -v -A -O gen:30:eth0:ipv4:131.114.33.200
KEY1=`grep 'gen 30' /proc/net/mpls_out | cut -d' ' -f1`
$TC filter add dev $INDEV parent ffff: protocol ip prio 1 u32 match ip
src 10.0.1.2

On LER_B

mplsadm -L eth0:0
mplsadm -A -I gen:30:0

I think the problem is: when the pk forwarding from 10.0.1.2 to
192.168.4.1 comes to ip_recv(  ) on LER_A,  ip_recv( ) doesn't  find
the fib.

So I've added :
on LER_A
mplsadm -v -B gen:30:eth0 -f 192.168.4.1

and patched the kernel file : /usr/src/linux/net/sched/sch_ingress
deleting  skb->mpls_index = TC_H_MIN(res.classid); and adding
skb->mpls_index = res.classid;

Now the ingress policing works

Any comments/help

Thanks in advance

[mpls-linux-general] MPLS configuration on LInux Router

[sakhter <she...@br...>]

Hi,

Is there anybody who can guide me through the steps(commands) to enable mpls
routing on a Linux router.I have made my linux box an Mpls router and
everything has been done properly,but I just wana make sure if following
commands(steps) are correct ;

- First , i assigned the label spaces to eth1 and eth2 ;

   mplsadm -v -L eth1:0
   mplsadm -v -L eth2:0

- Then, I added the routes to it( eth1...10.0.0.28, eth2...10.0.1.2,
gateway....10.0.0.27 & 10.0.1.1

     route add -host 10.0.0.27 gw 10.0.0.27
     route add -host 10.0.1.1 gw 10.0.1.1

     route add 10.0.0.27/32 gw 10.0.0.18
     route add 10.0.1.1/32 gw 10.0.1.2

- Then, I added MPLS labels ;

     mplsadm -v -A -B -O gen:16:eth1:ipv4:10.0.0.28 -f 10.0.0.27/32
     mplsadm -v -A -B -O gen:17:eth2:ipv4:10.0.1.2 -f 10.0.1.1/32

Please guide me if I am wrong anywhere or if I need to do anything else
instead of above.

I will appreciate prompt response from anybody who knows about it.

Thanks
Saeed

Ideally we would hear about interface failures via netlink.
Although on Linux lose of carrier is not converted into an
interface state for all drivers.

Correct.  On a "real" platform you would get the interface notification
and that would trigger LDP to bring down the adj on that link.

[mpls-linux-general] hello socket and link failure

[Scott L. <nat...@ya...>]

James,

Is there any way to know in the socket layer (TCP or
UDP)
that whether the physical link has failed?

I think sendto() does not tell you whether it really
sent the packet or hold it in the kernel memory.
If this is the case, the only way we stop sending
hellos (invoking sendto()) is to let
the hello timer expires (5sec * 3). Is this correct?

Thanks.

Scott

First get the latest version from CVS.

http://sourceforge.net/cvs/?group_id=15443

Second make sure you have the correct routes added to the linux routing table
and that LDP know about them:

prompt> show route

Turn on LDP tracing to see more of what is happening:

prompt> set trace 0xffffffff

Look in the READMEs for more 'show' commands.

[mpls-linux-general] help in ldp_linux

[L S. R. <ls...@ya...>]

hi all,
	i have not done really great thing,but what i observed is after starting
ldp_linux i am using "add global" as peer of that LSR and in the same way i am
doing in the other linux machine. both are establishing session but there is no
further negotiation. i am using ldp-portable-066.clear picture is:
IP addr of Host A is 172.16.2.165 Host B is 172.16.2.2
at host A:
add global 172.16.2.2
add interface eth0
at host B
add global 172.16.2.165
add interface eth0

then it is giving index  x 0xacdefgh/xx x and at the other end it is giving
"Gratuitous Srearch !!" but in some cases it is giving the error of recv_init
failed can't find adj. i not getting why it is giving this,
as i know this ldp_linux won't interact with mplsadm ,(if i am wrong
please correct me ),is this is the problem for that .
is it necessary to configure with mplsadm to communicate ldp peers

CR-LDP support is not complete.  I have the beginings of a TE-MIB implemented
but I still need to add the CR support to LDP.

Use the -DMPLS_LINUX flag to compile ldp-portable to make calls to the Linux
kernel to setup the MPLS components.

I suggest using CVS to get the latest version of ldp-portable (I haven't been
releasing packages because it is changing too much)

There are some example docs in CVS of how tro configure ldp-portable.
