[mpls-linux-general] what's the next step to dig in LDP code

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

Hi James,

Last time you told me to do "Start ldpd, telnet localhost 2610, =
configure, turn on LDP globally, turn on LDP on an interface, use the =
'?' key to figure out what commands are availble".

I have tried it , and I got the result below, there seems only few =
comands available.  What should I do on next step??

uml-1(config-ldp)#
  disable           Disable
  end               End current mode and change to enable mode.
  exit              Exit current mode and down to previous mode
  help              Description of the interactive help system
  list              Print command list
  lsp-control-mode  control mode
  lsr-id            LDP Label Switch Router Identifier
  no                Negate a command or set its defaults
  quit              Exit current mode and down to previous mode
  show              Show running system information
  trace             LDP debugging
  write             Write running configuration to memory, network, or
                    terminal

Start ldpd, telnet localhost 2610, configure,
turn on LDP globally, turn on LDP on an interface, use the '?' key to =

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

If you were to search the mailing list you would find many of my
responses in which I state that quagga+ldp is not ready for users.  In
otherwords it has bugs .. lots of them.  If you're not going to dig into
the code and fix bugs, it's not worth your time.

BTW please send messages about MPLS linux to the mailing list, not
to the admin ....

If you search the mailing list you will see what my standard response is:

On linux, traffic prioritization is only slight different for MPLS vs IPv4.
So the first step is for you to learn how to do traffic prioritization
for IPv4 traffic (google for it there are plenty of HOWTOs about it), then
show me the commands to do the prioritization you want via IPv4 and I can
tell you how to modify them to work with MPLS.

If all you want to do is puts some EXP bits on the wire, just add the
'set-exp' opcode to your instructions ('set-exp' is the key word you
can use with the newer 'mpls' utility, if you are using the older
'mplsadm2' utility then you would use the 'set_exp' key word)

OK.  Now I understand your question.  A 'peek' past the last label is the
same as a 'dlv', the packet is delivered to layer 3.

The reason this semantic was added was an upstream LSR will not always know
if the label it allocats will be used by itself or as part of a labelstack.
Thus by always doing a pop/peek either the next label in the stack will be
searched for, or the packet will be send to the layer 3 protocol bound to
the ILM.

BTW you should switch to the newest mpls-linux and start using the 'mpls'
utility, as opposed to using mplsadm2.

Hi James,

I remember last time you gived me the answer about LDP question which =
was showed below

"Have your tried to run it yet?  Try that and start working on the first =
segfault you hit ...."

Now, I want to know how to try it, if Quagga+LDP is not ready for users, =
how do I try it? Could you give me a hint?

Quagga+LDP is not ready for users.  It will not work.  If you plan to help
fix it, grab the latest code and dig in.

Hi James,

I am trying to run LDP now. But I don't know where to start? And how to =
try it. Could you give me some examples or some scenarios?

Thanks

I do not understand your question.

To explicitly force an ILM to pop all labels and send the packet to layer

[<ram...@wi...>]

Hi,

In transit,through mplsadm I added an incoming label.so the default
operation is pop and peek.Now an packet comes with that label but no
binding is there.
Now what will happen whether the packet will dropped or it will send to
ip layer and iprouting will take place?

What is the use of dlv operation?

Thanks in advance.

[mpls-linux-general] Tunnel with wlan0?

[mynor <myn...@gm...>]

I have read the configuration with Hierarchy via 'Tunnel interface' in
your documentation.
What I didn't understand is what interface represent by 'wlan0'?

Is it means that using tunnel can solve many LSPs in just one path?

Is it packet loss is cause by ping from different tunnel?

For your information, I'm doing a research for my degree, comparing
MPLS network performance with current routing protocol network.

I still don't know how to configure Zebra or Quagga. If there is a

I'm Mynor

I have try installing MPLS-Linux in 2 platform using VMWare
What I'm confusing about is what different LER and LSR and if I want
to make both of them in one network together, is it needs different

I want to make 3 LSP after the LSR and Engress will receive it and unlabel it.
How can I do it and where can I get manual or documentation about it?

Re: [mpls-linux-general] QoS on MPLS-Linux

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

Do a search on the mailing list and you will see that doing QoS on
MPLS Linux is very much like doing QoS on normal Linux IPv4.  So I suggest
figuring that out first (do a google search and you will get plenty of hits=
).
Once you can describe to me what you want to do and the commands of how
you would setup it up for Linux IPv4, then I can tell you how to make it
work over MPLS Linux.

The mpls-te commands only control the flow of OSPF-TE LSAs.  Those commands
are part of the main quagga distribution, you will have to ask on the quagga
mailing list about the usage.  Commands like:

mpls static ...
label-map ...
ip route ... gen ...
create mpls-tunnel ...

=2E.. are commands added by me.  You can ask questions about them here on t=
he
mpls-linux-general mailing list.

Correct me if I'm wrong, but IPSEC looks like an normal IP packet to the
lower layers.  Therefore MPLS will not even know it is carrying IPSEC
packets.  Have you tried yet?

Re: [mpls-linux-general] Ping in MPLS

Hello again,
    I have been reading some documents about MPLS and an Internet draft
(draft-ietf-mpls-lsp-ping-07.txt) about how works mpls ping but I don=B4t
understand very well how it works (how to fill in the differents fields o=

the MPLS UDP echo request packet, what have to do a LSR when it receives =
an
MPLS echo request or an MPLS echo reply, etc). Can you send me where I ca=

see documents about how works mpls ping and an example of it in order to
implement it? About what you say in the mail below, where can I obtain th=
e
code of the MPLS socket implementation in order to finish it and informat=
ion
about what do the functions that are implemented? Finally, I don=B4t
understand very well the part in wich you explain to me NHLFE Key and ILM.
Can you say more details about it?

Thanks in advance.

Tomas.
