Re: [mpls-linux-general] how to build LSP using IPv6

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

I have never tested andy of the IPv6 support.  If you are willing to
work with me, I'm sure we can fix the userland programs and debug the
kernel.

Since you are a newbie, I'm going to suggest the easiest path possible.

The first thing, is you should install Fedora Core 2 as opposed to 
redhat 9.  The reason for this is that I build RPMs for Fedora Core 2.
After you have install Fedora Core 2 on your machines then download:

    iproute-2.4.7-14mpls_1_938.i386.rpm
    kernel-2.6.8-1.521mpls_1_938a.i686.rpm
    mplsadm2-1.938-1.i386.rpm

From http://sourceforge.net/projects/mpls-linux/ in the 'Files' area.

Then read http://www.dirac.org/linux/rpm.html
In particular you will want to 'upgrade' iproute-2.4.7-14mpls_1_938.i386.rpm
and 'install' mplsadm2-1.938-1.i386.rpm and
kernel-2.6.8-1.521mpls_1_938a.i686.rpm

After you have these RPMs installed and have rebooted to the new kernel,
then read the example on http://mpls-linux.sourceforge.net/

I hope this is enough info to get you started.  Please remember this
mailing list is for discussing mpls-linux related issues ;-)

Good luck

I want to build LSP with 2 hosts using IPv6, with the 
topology below:

[host A]------------------------------------------[host B]
eth0=2002:1::a01:1dd/32 
                     eth0=2002:1::a01:1de/32

I have tried the command below on host A:

[root@PCA root]# mplsadm2 -O KEY1 -o

according from the output above i think the IPV6 address 
assumed as instructions not as address, i would like to 
ask how to build LSP with 2 hosts using IPv6?

Hi all,
I have just join the mailing list and found it very useful as you
people are doing a great job. Plz tell me the installation process of 
mpls on redhat linux 9. plz describe the process in detail as i am a
newbie to linux that is what files i have to download and what command
should i run what are the pre-requirments for the installation.

You're using the old syntax.  Where did you see this syntax?

It is supposed to be:

ip route add 11.0.1.2/32 via 11.0.1.2 spec_nh 0x8847 0x2

Where 0x8847 tells the spec_nh system that this is a MPLS nexthop, and
0x2 tells which NHLFE to use.

[mpls-linux-general] Error: either: "to" is duplicate or "lsp" is a garbage

[<m9...@cn...>]

Hi,

I got a problem when I try the MPLS-Linux example after I install the =
mpls-linux software. The steps I did were:

[root@ root]# mplsadm2 -A -O 0
Key: 0x00000002
Out Segment add: Success
[root@ root]# mplsadm2 -O 0x2 -o push:gen:10000:set:eth1:ipv4:11.0.1.2
Out Instr: Success
[root@ root]# ip route add 11.0.1.2/32 via 11.0.1.2 lsp 0x2
Error: either: "to" is duplicate or "lsp" is a garbage

Is there anything wrong?


Thanks.

Your using ethernet interfaces right?  Whenever you send a packet
over ethernet you need to know the MAC address of the peer on that ethernet
segment.  So that means the nexthop definition in the NHLFE needs to
somehow tell MPLS what the MAC address of the nexthop LSR/LER is.

Would you rather type an IP address or a MAC address? :-)  The IP address
is used to ARP for the MAC of the nexthop LSR/LER.

(BTW the nexthop definition in mplsadm2 is the 'set:eth0:ipv4:1.1.1.1'
instruction)

If you were using interfaces which do not need ARP (ie PPP interfaces) then
your nexthop defintion would be 'set:ppp0'.

The nexthop definition is not a FEC.  A FEC refers to the ultimate destination,
not an intermediate hop along the way.

If you wanted to type MAC addresses everywhere, then yes you could have
a MPLS core without using IP addresses.  mpls-linux would need some minor
modifications for that to work.

Sure ;-)

   ("maplsadm2 .... :eth1:A.B.C.D")

This bothered my as well for the simple example (without label
stacking).  When thinking of smart LERs and dumb LSRs, IP-based FECs
should be needed at the borders only (e.g. R1 will have an entry towards
the IP adress of R4, the right border node, not towards R2).  I know
many MPLS networks use IP in the core to find best paths, i.e. using
OSPF-TE and the like, but can we as well build MPLS-only, non-IP cores
with mpls-linux?=20

I haven't implemented all of the command line args in the new "mpls" program

Hello,

I have the following lab network:

  --[R1]--[R2]--[R3]--[R4]--

I successfully set up manually an LSP from R1 to R4.  However, I now
want to set up additional label stacking between R2 and R3 manually(!)
for demonstrative purposes ("look, this is how label stacking works"). =20

Unfortunately I was not able to do this neither with the "mplsadm2" nor
with the "mpls" command (I prefer to use the latter).  Note that I do
*not* want to use tunnel interfaces.  Is there a neat way to get it done
without using IP/tunnel ifs?

My guesss was to set up appropriate NHLFE entries, like

  mpls nhlfe add key 0x10 instructions nexthop eth0 push gen 1234

but all I get is "MPLS: invalid last op PUSH, len =3D 1(1)", so I'm not
sure what went wrong here....

[mpls-linux-general] sending mpls packet

[soheila j. <sja...@ya...>]

Hi James,
I could establish session between two computers.
And now they send hello msg and keepalive msg and
address msg together and they know others as neighber.
I want to implement mpls packet and send packet from
one computer and recieve on another.
I know socket programming in a little.
What should I do?
Do you know any books or refrences?
Please help me
Best ragards.

Just as with the original fedora 2 kernel there is a RPM that contains the
kernel image itself (vmlinuz) and a RPM for the kernel source that was
used to generate the kernel image.

If you just want to run a MPLS enabled kernel you download
kernel-2.6.8-1.521mpls_1_938a.i686.rpm, if you want to look at the
source code that was used to generate the MPLS enabled kernel, you download
kernel-sourcecode-2.6.8-1.521mpls_1_938a.i686.rpm


> Is "MPLS for Linux project" going to support "Draft-Martini" ? If not, what files (which rpm files) should I download to add Martini feature?

In the forwarding plane:
I have a project called l2cc which enables the linux network stack to
cross connect layer 2 packet onto LSPs.

Currently it is a seperate project and I have not release a kernel that
contains both MPLS and L2CC.  I will be doing that soon. (that kernel will
also contain my Linux VRF code as well).

In the signalling plane:
I have the infrastructure needed to implement the Martini extentions to
LDP, but I have not done the work yet.  I would accept patches that worked
towards this.  If you plan on working on this, let me know and I'll
give you some pointers on where to start.

Re: Re: [mpls-linux-general] Newbie problems

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

If you use the newest kernel and iptables I've posted (1.938)
you can use iptables to sent specific traffic down a LSP.

iptables -A OUTPUT -d 1.1.1.1/32 -j spec_nh --spec_nh 0x8847:0x2

Where 0x8847 tells the spec_nh system your setting a MPLS nexthop
and 0x2 is the key of the NHLFE created via mplsadm2.

(you can use other iptables 'filters', see you an iptables howto
for more info on selecting traffic)  The key to this working is the
-A OUTPUT and the -j spec_nh --spec_nh 0x8847:0x2, in between there you
can use whatever iptables 'filters' you want.

Read the 'RPM Support' section of:

BTW I'm in the middle of releasing mpls-linux 1.938, it has some important
