[mpls-linux-general] Compilation Problems

[Massimo M. <ma...@ne...>]

Hi all.

I have patched kernel 2.6.11 with mpls patch.

When I try to compile, I have this error back:

net/mpls/af_mpls.c:40: error: `sock_no_release' undeclared here (not in 
a function)
net/mpls/af_mpls.c:40: error: initializer element is not constant
net/mpls/af_mpls.c:40: error: (near initialization for 
`mpls_sk_ops.release')
make[2]: *** [net/mpls/af_mpls.o] Error 1
make[1]: *** [net/mpls] Error 2
make: *** [net] Error 2

I have gcc 3.4.0, and the mpls drivers are compiled into the kernel and 
not as modules.

Thank you for any help.

Re: [mpls-linux-general] About labels and interfaces

[jrussi <jr...@uo...>]

Thank you.

I found the following at you developer's guide:

"The proposed approach in the current MPLS for Linux
implementation is to add a label space to a given interface ..."

For outgoing segments you do it too. The "key" structure is
a labelspace for outgoing segments. You use one labespace
per outgoing segment.

Thank you again,

Josdeyvi

It's a two step process, look at:
mpls labelspace show

Find the labelspace of the interface your interested in:
Then look for that labelspace in:
mpls ilm show

Re: [mpls-linux-general] difference between segment and label

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

segment, as in in-segment and out-segment comes directly from the LSR-MIB.
In-segments and out-segments represent MPLS entities what have one or more
labels associated with them.

[mpls-linux-general] About labels and interfaces

[jrussi <jr...@uo...>]

How can I verify wich label (and labelspace) is assigned to
each interface?

I see that several interfaces can use the same labelspace,
right? So the command mpls ilm show will not give me a
per-interface information. Is that correct? Any solution?

There is no development schedule.  I work on this stuff in my free time

Re: [mpls-linux-general] Do we must have mpls-linux enabled kernel when we test LDP

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

If you want to test quagga-mpls without a MPLS-linux kernel you
can change zebra/Makefile.am:

-mpls_method =3D mpls_netlink.o
+mpls_method =3D mpls_null.o

Then recompile.  The result is that everything from a signaling perspective
is the same. (LDP sends zebra API messages to zebra, zebra populates is
MPLS database).  The only thing that changes is none of the MPLS segments
are created in the forwarding plane.

Hi James,

I have a basic question about LDP testing.

Do we must have mpls-linux enabled kernel when we test LDP? Because I =

I am not sure this concept is correct or not? Please correct me, thanks.

I have attached the concerned code. Here the code run alright.

1)2 nodes node0 and node1 attached to LSR2 which in turn is attached to LSR3 
and LSR5.
2)I have specified the link node0-LSR2 and link node1-LSR2 as 1mb
and the LSR2-LSR3 as 1mb while LSR2-LSR5 as 0.2 mb.
3)And i specified a common destination node node9.
4)Now when i run the simulation traffic from node0 and node 1 both use the 
LSR2-LSR5instead of the LSR2-LSR3 resulting in unnecessary packet dropping.

Re: [mpls-linux-general] I got a error when I restart "mpls ip" command on interface

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

Good work.

A quick look at the trace file shows:

PRT: ldp_cfg_entity_set: no such interface
entity delete
EXIT: ldp_cfg_entity_set
ENTER: ldp_cfg_entity_get
EXIT: ldp_cfg_entity_get
lt-ldpd: ldp_interface.c:101: ldp_interface_startup: Assertion `ldp &&
+li->iff.index' failed.
Aborted

Note the 'no such interface'.  That means quagga tried to configure
an entity for an interface which LDP does not know about.  Trying looking
through the trace to see if any of the ldp_cfg_if_* calls result in
an error ('PRT' usually indicates an error I think).

Re: [mpls-linux-general] I hit the first point when I dig in LDP code

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

What version of mpls-linux are you running?
Make sure to start ldpd in the forground (ie not as a daemon) and redirect
it's STDERR and STDOUT to a file.  My guess is that there are some
error msgs being printed by the ldpd daemon.  You can also try enabling
all tracing (which also goes to STDOUT).

conf t
mpls ip
trace all
exit
int eth0
mpls ip

Try that and see if you can find anything in the output from ldpd.

[mpls-linux-general] I hit the first point when I dig in LDP code

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

Hi James,

I follow the steps that you told me last time.
The two hosts can't establish LDP session.=20
In order to avoid wrong configure I enter, I capture out my configure =
below.

Host A's OSPF configure
Current configure:
!
hostname ospfd
password zebra
log stdout
!
!
!
interface eth0
!
interface eth1
!
interface lo
!
interface sit0
!
router ospf
 network 192.168.1.0/24 area 0.0.0.1
!
line vty
!
end

Host A's LDP configure
uml-1# conf t
uml-1(config)# mpls ip
uml-1(config-ldp)# exit
uml-1(config)# int eth1
uml-1(config-if)# mpls ip
uml-1(config-ldp)# end
uml-1# show ldp

What's the problem? and What should I do?

One doesn't exist yet.  You can look to the output of 'mpls -h' for
the syntax.  You can also look to the examples at http://mpls-linux.sf.net/

Yes, it is used to bind a ILM to a NHLFE.  It is akin to the '-B' bind
command from mplsadm2.  'xc' stands for cross connect.

If you have a particular question about how to do something
with 'mpls' let me know, and I'll try to point you in the right
direction.

[mpls-linux-general] label stack example with the new mpls command

[jrussi <jr...@uo...>]

Hi,

Where can I find a complete description of the new "mpls"
interface? By the way, what is the xc option? Is it a cross
connection (label to label) option?

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

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

First make sure you have OSPF up and running between the hosts across
the same interfaces as you will run LDP.

It's been a while since I have tried, but I believe all you need to=20
turn on is:

ldpd> conf t
ldpd(config)# mpls ldp
ldpd(config-ldp)# exit
ldpd(config)# int eth0
ldpd(config-if)# mpls ip
ldpd(config-ldp)# end
ldpd> show ldp
ldpd> show ldp neigh
ldpd> show ldp ?

If you do this on two hosts, they should form an adj, and then a session
then start exchanging labels.  If you get that far, then try to break thing=
s:
-disable/enable ldp globally
-disable/enable ldp on an interface
-remove/add ldp on an inteface
-remove/add lgp globablly

If you get this far then start playing with addresses:
-add/remove an IP address to a different interface (you should see the
 address be added and removed on the LDP peer

If you get this far then start playing with routes:
-add/remove static routes which get advertised into OSPF

Let me know where things break.  Make sure to keep track of what you
did to break things (consider using the unix utility 'script' to capture
everything you do).

Good luck
