I don't mind if it don't work in this release, but I thougth it could
help with debugging.
If I do
mpls ilm add label gen 200 labelspace 2
it works well, but when I try to add some instructions:
[root@localhost ~]# mpls ilm add label gen 200 labelspace 2
instructions pop set-exp 0x3 forward 0x2
RTNETLINK answers: No such process
[root@localhost ~]# mpls ilm add label gen 200 labelspace 0
instructions pop set-exp 0x3 forward 0x2
[root@localhost ~]# mpls ilm add label gen 200 labelspace 2
instructions pop set-exp 0x3 forward 0x2
[root@localhost ~]# mpls ilm show
ILM entry label gen 200 labelspace 2 proto ipv4
        pop peek  (0 bytes, 0 pkts)
ILM entry label gen 200 labelspace 0 proto ipv4
        pop set-exp 3 forward key 0x00000002  (0 bytes, 0 pkts)

If I want to add the label to a labelspace per interface, and I want
to do something (not the default pop), I get an error. If I add that
label to the labelspace 0 before, I don't get the error, but the
result is the default pop.

I'm sorry. The command I wrote was right, but I forgot to set the
interface into the labelspace. I've tried it with the tunnel interface
and it works well. Thank you very much.

But I'm a bit confused with the tunnel interface. When or why is it useful?
If I send traffic trought the mpls0 interface I have to do,
mpls tunnel set dev mpls0 nhlfe KEY
but I can forward traffic to that nhlfe key without the mpls0 interface.
And when I use set-rx-if and the kernel thinks the traffic comes
throught the mpls0 interface:
if I'm going to do a MPLS forward I don't need the information;
if I'm going to do a IP forward, I can do it with   ILM(pop,
forward)-->NHLFE(nexthop)   or ILM(pop) and after an IP search.

Javier,

Thank you for trying MPLS Linux.  I've answered your questions in-line.
Please continue to send any questions you have to the mpls-linux-general
mailing list and I or others will do our best to answer your questions.

I encourage you to upgrade to Fedora 7 or 8 and use the latest
packages available.

    [root@mpls8-1 ~]# mpls ilm add label gen 100 labelspace 2
    [root@mpls8-1 ~]# mpls ilm add label gen 100 labelspace 0

push without pop is not supported and it against RFC 3031.  By doing
a push without pop your exposing nodes further along the LSP to labels
they have not assigned.

       A ----> B -----> C    

In this picture the arrows represent the direction the packets are flowing.
Currently the only form of label allocation that is standardized is down
stream label allocation which mean the next hop peer assigns the label
on which a MPLS speaker can sent traffic.  In other words, B assigns labels
for which A can send traffic to B.  By doing a push without pop, you are
exposing some node beyond B to labels for which it did do assign.

If you are trying to accomplish label stacking such as is found in MPLS BGP
VPNs or by-pass tunnels, then you will want to utilize the the 'forward'
instruction on a NHLFE to product layers of indirection.

ILM (peek,pop,fwd) -> NHLFE (push,fwd) -> NHLFE (push,nexthop)

set-rx-if is used to set the interface you want to the kernel to believe
the packet arrived on.  It can be used in combination with the MPLS tunnel
interface to provide a bi-direction interface (MPLS tunnel interfaces are
uni-directional since they represent a uni-directional LSP).

I believe set-rx-if must be the last instruction.

First of all, I'm working with mpls-1.950 on fc4 and I think these
things aren't working well.
I don't know if they work on newer releases.

1.
I can add instructions to labelspace 0, but I can't to others:
[root@localhost ~]# mpls ilm add label gen 100 labelspace 0
instructions forward 0x2
[root@localhost ~]# mpls ilm add label gen 100 labelspace 2
instructions forward 0x2
RTNETLINK answers: No such process

2.
I have a problem when I try to add a label to a packet that already
carries one (only one).
In the LSR, I do:
mpls nhlfe add key 0 instructions push gen 2000 nexthop eth0 ipv4 10.6.44.6
mpls ilm add label gen 1000 instructions forward 0x2

And in the ingress LER I do:
mpls nhlfe change key 0x2 instructions push gen 500 push gen 1000
nexthop eth0 ipv4 10.6.44.2
or:
mpls nhlfe change key 0x2 instructions push gen 1000 nexthop eth0 ipv4 10.6.44.2

In the first case, there isn't any problems, but in the second, the S
bit in the MPLS header
with the label 2000 is set to 1. And it must be 0.
I know that I can pop the label 1000 and push it again, solving the
problem; but if I want
to merge some LSP in that tunnel, I have to repeat the nhlfe line for each LSP.
And I think it isn't the desired behaviour.

3.
I don't know how to use
set-rx-if <NAME> forward <KEY>
I tried this:
[root@localhost ~]# mpls ilm add label gen 255 instructions set-rx-if
eth0 forward 0x2
RTNETLINK answers: Operation not permitted

Thank you.

Hello everybody,

I am scholar of "Enginyeria i arquitectura La Salle" an University of
Barcelona. Recently they suggest me a project of implement RSVP-TE on quagga
routers. I  have read that in the past there are some initiatives in this
list to implement a daemon of RSVP-TE. The final idea is to interconnect
Cisco routers and Linux Routers and that they can talk RSVP-TE to implement
MPLS-TE. I think that there are an implementation of OSPF-TE daemon and if
I'm not wrong the only thing that is missing is the RSVP-TE daemon.

Does anybody knows the state of the art of RSVP-TE in MPLS-Linux?

I am completely new on developing in Linux environment and specifically in
open source project like MPLS-Linux but I'm very enthusiastic and motivated
on it. I think that it could be exciting to collaborate with us to success
on the project.

Please let me know your opinion, and please apologize me for my level of
English. I am working on it too :)

Regards,

Jesús Nubiola

Interesting.  Can put a host on one side of the LER<->LER and have
it send the DNS packet?  Then capture the packet on the IPv4 link and
capture the same packet on the MPLS link?  I want to see if the packet
size increases by more then 4 bytes, that would explain the invalid
checksum.

The problem does occur in a LER<--->LER LSP.  I also have proven that 
there is a checksum problem with UDP packets.  If I turn off MPLS dns 
udp packets do not generate a checksum error but when I standup a MPLS 
LSP the path generates UDP checksum errors on DNS queries.  Below is a 
wireshark capture of one packet with a checksum erro, hope it helps.

James

I dont think the push is the problem.  First, it can't be removed based 
on how the LER needs to be configured.  Remembering my network 
configuration is LER_1<->LSR<->LER_2, below is the CLI's MPLS commands 
for each router.  Also, another test using "iperf -u" works, although 
performance is very poor, so it seems only dns and traceroute using udp 
are not working.

Iperf output:

Well give the PHP a shot later today and let U know.  Yes, I've already 
tested the -I option.

PHP config example:

    mpls nhlfe add key 0 instructions nexthop eth0 ipv4 192.168.1.1
    (notice no push in the instructions)

    Then bind it to a route or netfilter rule like normal.

Can you try 'traceroute -I' which sends ICMP not UDP packets.

Not familiar with the PHP implementation, let me collect up the test 
configuration and send it to you for advice on what you want.  A test 
update, the problem seems, so far, to only manifest itself with dns and 
traceroute.  An "iperf -u -c [target_ip}" test does not have a problem.

Hi,

When I apply the patch quagga-mpls.diff (ldp-portable) to quagga-0.99.6,
I get below error. How can I rectify this error and move further?

I am new to using quagga, so any pointers to documentation/setups will
be appreciated.

Thanks,
Raj

Subject: Re: [mpls-linux-general] UDP traffic problem

I haven't seen it, but I can look into it.  Can you try routing traffic
through the same boxes, but use PHP (ie NHLFE without push) at each hop
to see if that breaks it too?

Anyone notice udp traffic problems through a LER<->LSR<->LER LSP?  For 
example, if I attempt to issue the command "traceroute -n [target-ip]" 
the traceroute will fail.  If I add the TCP switch, aka "traceroute -n 
-T [target-ip]", the trace works fine.  Also, any nslookups fail, again 
because the lookup request are udp packets.  Wireshark is showing 
checksum errors on the traceroute packets but I'm not sure that is 
causing the problem as the error maybe misleading.

If the goal is to use NFS as root filesystem all one needs to do is create
a initrd with the NFS modules, it is not required to build a kernel
with NFS statically included.

The key to allowing this to happen is you need to make sure your
/etc/fstab has an entry for the root filesystem that spells out what NFS
resource to use.

For example:

    172.16.1.1:/my/nfs/root / nfs defaults 0 0

Then install the MPLS enabled kernel RPM and as part of that it builds
an initrd, and now that you have a fstab that indicates where to get root
from it should build you a nfs enabled initrd.

James, the original problem was that he needs NFS compiled into the kernel
in order to boot and the binary kernel you provide has it as a module...

Hello Rachid,

About a year and a half ago I experimented with LDP, but it was too instable
to be of any use (it crashed when setting up a LPD adjacency). Now, I've
heard on the mailing list that it is more stable and should work. You should
download the quagga binary (or source) from sourceforge and install/compile
it. You should configure ospf routing first (and make sure it works) and
after that start ldp.

Configuring LDP is easy, something like:
#conf t
(config)# mpls ldp
(config-ldp)#lsr-id *one.of.the.ips.from.this.router*
(config-ldp)#transport-address *one.of.the.ips.from.this.router
*(config-ldp)#address-mode ldp
(config-ldp)#exit
(config)#interface eth1
(config-if)#mpls ip
(config-if)#distribution-mode du
(config-if)#end
#show ldp

Not all the parameters are necessary. The minimum are mpls ldp in global
config mode and mpls ip on the interfaces with mpls.

Ask for more details on the mailing list, in case of trouble.

Adrian

I haven't really been following along with your setup, so excuse me
if I'm asking questions that you already answered.

Why are you install SRPMs as opposed to the binary RPMs?  If you're
on a different distribution and compiling them by hand, please include the
commands you used to do the compilation and installation.

Hello All,

I have compiled and installed 2.6.22 mpls enabled
kernel(kernel-2.6.22.5-76.fc7.mpls.1.958.src.rpm), and also installed
the following packages:-

ebtables-2.0.8-1.fc7.mpls.1.958b.src.rpm 

iproute-2.6.20-2.fc7.mpls.1.958b.src.rpm 

iptables-1.3.8-2.1.fc7.mpls.1.958.src.rpm

But unable to find mpls utility to configure system, please let me know
if I am missing any package or any patch. 

System Information:-

[root@localhost linux-2.6.22]# cat /var/log/dmesg | grep MPLS

MPLS: version 1.958

MPLS: protocol driver interface - <jl...@mi...>

MPLS: IPv4 over MPLS support

MPLS: Ethernet over MPLS support

[root@localhost linux-2.6.22]# sysctl -A|grep os

kernel.ostype = Linux

kernel.osrelease = 2.6.22.5

kernel.hostname = localhost.localdomain

net.core.message_cost = 5

net.ipv4.route.error_cost = 1000

net.netfilter.nf_conntrack_tcp_timeout_close_wait = 60

net.netfilter.nf_conntrack_tcp_timeout_close = 10

net.netfilter.nf_conntrack_tcp_loose = 1

dev.cdrom.info = Can close tray:                1

dev.cdrom.autoclose = 1

[root@localhost linux-2.6.22]#

Kernel Configuration enabled are:-

1.

In Networking Options the following items will be compiled in kernel :

<*> Multiprotocol Label Switching

<*> MPLS: Virtual tunnel interface

<*> 802.1d Ethernet Bridging

<*> Bridge: MPLS support

2.

In Bridge: Netfilter configuration menu the following minimum options
will be selected:

<*> Ethernet Bridge tables (ebtables) support

<*> ebt: broute table support

<*> ebt: filter table support

<*> ebt: nat table support

<*> ebt: 802.3 filter support

<*> ebt: MPLS target support

3.

In Networking Options select QoS and fair queueing

Thanks & Regards

Bhartendu M.
