Re: [mpls-linux-general] load sharing in mpls - linux

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

Do you want to load share from ingress LER to egress LER (packets come
in IP and need to be sent down one of two LSPs) or do you want load
sharing to occur in the middle of the MPLS cloud (packets come in with MP=
LS
shim and need to be switch down one of two LSPs)?

[mpls-linux-general] load sharing in mpls - linux

[Miguel G. <mg...@fi...>]

Hi all,
I'm trying to develope an algorithm of load sharing based in the delays =
in the different LSPs, but I don=B4t know how I can do load sharing in =
linux. I have installed mpls-linux-1.170, the idea is to create =
statically different LSPs to reach a same LER. Does anybody know how can =
I do load sharing through different LSPs in Linux?
I=B4d really appreciate any help.
Thanks,
Miguel.

AW: [mpls-linux-general] when mpls_recv

[Georg K. <gk...@gi...>]

Hi roro,

>     is mpls_rcv invoked when a packet reach ingress LSR? If so, which 
> sentence invoke it ?

The mpls_init function registers the Packet Type ETH_P_MPLS_UC to be received 
by the function mpls_rcv. So mpls_rcv is called almost immediately after the
device driver calls netif_rx(). You won't find any mpls_rcv reference in the 
kernel, instead the registration works with the function dev_add_pack();

> And where is mpls_send invoked?

mpls_send is called by mpls_output2, is called by mpls_output_shim is called by
mpls_output which is stored along with the next hop info of the FIB. (see 
mpls_make_dst())

hi,all
    I am reading mpls-linux source code, but I encoutered problems.
    is mpls_rcv invoked when a packet reach ingress LSR? If so, which sentence invoke it ? And where is mpls_send invoked?
    Can you tell me the detailed flow when a packet reach and leave ? It will be appreciated.
    Thanks a lot

[mpls-linux-general] LSP -

[deepak <dxb...@wi...>]

hi all
well im in the testing phase of this mpls-linux forwarding statically 
when i have a scenario like this one :Setup
-----
 ---------             ---------
 |   A   |             |   B   |
 ---------             ---------
     |eth0                 |eth0
     |17.130               |18.114
-----------------------------------
         128.104.16.0/22

here any ways they will ping and the transfer of packets take place but how do 
i know that the LSP is created and the packets use the LSP  is there any 
specific display of labels .......and how do i view the label swapping i 
havent installed ldp ....and one more thing 
i had an error using ip route add to add the lsr ie the next hop so i used 
ip route add 128.104.18.114 via 128.104.17.130 on A and vice versa on B 
will this work ????/help wanted urgently 
thanking you in advance
deepak

You can have OSPF modify it for you:

conf t
interface eth0
  ip ospf cost 15

I think you will need to change OSPF as well.  Without changing OSPF
LDP is presented with 2 equal cost OSPF routes, this is the fundamental
problem for the multipath case.

numbers of incoming/outgoig see above

Multipath and merging.

multipath is bad.  I have idea how to support it, but I know for sure it
will cause things to behave badly.  (as an FYI RFC3036 explicitly says it
doesn't support multipath.  Any solution that vendors have put in place it
proprietary.)

Evil.  Lets try walking before running.  Simplify the topo and let me know
if you still see so much instability.

Eventually mplsd will be able to support this type of 'complex' topo, but
I'm not there yet.  Maybe with you help we can nail down some of the real
troubled areas.

sorry, i afraid i was confused too...
of course im using the latest cvs version of the ldp patch for zebra and
zebra + mplsd and latest patch for the linux kernel....

i started with a simple setup, with static routes in zebra.conf and a 
simple mplsd.conf:

hostname LSR-2
password pppp
enable password pppp
!
!
mpls ldp
! trace debug
! trace event
! trace normal
! trace notification
! trace path
! trace policy
! trace state
  egress connected
  address-mode ldp
!
interface lo
!
interface eth1
  mpls ldp
!
interface dummy0
!
interface eth2
  mpls ldp
!
interface eth3
  mpls ldp
!
interface eth0
!
line vty
  exec-timeout 0 0
!


there was ldp traffic, but no label assigns to remote routes...

i can't reproduce this behaviour again, because i changed the setup and 
use now ospfd too (without static routes) :-)
simple setup with to areas:
area 1: 1 2 7 4
area 2: 3 5 6


now i see the label information and can test them with a ping
(dumping it with a modified uml_switch), but there is a other problem:

mpls_in and mpls_out are constantly growing until around 220 and more 
(peak was 682) enries for in and 35 for LER-1 - then they decrease 
rapidly to something about 40...

do you have any ideas why?

which debugging output would be usefull (which config)?

btw: the systems runs very unstable (i use a while true loop for mplsd),
especially LER-7 (i set the two egress routes per script and don't use 
them in zebra,ospfd,mplsd - otherwise it chrashes immediately)


my testsetup:

          .--------LSR_2-----------.
         /              \          |
        /                LSR_5     |
       /                /     \    |   /
      /                /       \   |  /
----LER_1--------LSR_3         LER_7
      \                \       /   |  \
       \                \     /    |   \
        \                LSR_6     |
         \              /          |
          '--------LSR_4-----------'

     |----------- MPLS ------------|

From reading your other e-mails it looks like you are going down the correct
path working on setting up static LSPs.  I suggest you continue down that
path.

When it does become time to start wokring on setting up dynamic LSPs via
LDP, I suggest you start by learning how to setup LDP between two cisco
routers.  Then figure how to run OSPF between a cisco router and zebra,
then finally add zebra+ldp into the mix.

Not at this time, but it is being worked on.

Re: [mpls-linux-general] MPLS (new user)

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

Start by getting the mpls-linux package from sourceforge and reading the
README files it contains.
(http://sourceforge.net/project/showfiles.php?group_id=3D15443)

Before jumping into the world QoS with mpls-linux, make sure you understa=
nd
howto do QoS with linux first.

mpls-linux is a implementation of MPLS forwarding for the Linux kernel.

ldp-portable is an implementation of RFC3036.  It has a patch that you ca=
n use
with zebra (http://zebra.org) to create a LDP speaker that interacts with
routing.  Before working with ldp-portable + zebra, make sure you know ho=
w
to user zebra first.

The title has me a bit confused.  ldp_linux no longer exists, the only wa=
y
I provide for you to run LDP is with zebra. (using the mplsd daemon).

As far as I know mplsd can create LSPs correctly for the intended environ=
ment
(LSPs being setup for the LDP Identifier) in DU ordered control.  Of cour=
se
not every one understands the ramifications of that statment.

Start out by describing what you are trying to do, what you are observing
and what you expected to see.  Please include a ascii drawing of you setu=
p.

[mpls-linux-general] hi prob

[deepak <dxb...@wi...>]

hi all 
ihad emailed u guys abt the problem i faced when i used ip route add command 
to add to that im givin the details on which machine i did what ....

[root@localhost net]# cat /proc/net/mpls_*
0x00011001 0/0/0 gen 17 0 1 POP PEEK

0x00022001 0/0/0 gen 34 0 1 POP PEEK 
eth0	0	8
0x00000004 0/0/0 1 PUSH(gen 17) SET(eth0,192.168.6.60)
01010702

how do i delete the 0x00011001 & 0x00022001 keys that was the result of
 root# mplsadm -A -B -O gen:2614:eth0:ipv4:192.168.6.60 -f 192.168.6.60/32
 root# mplsadm -A -I gen:1234:0

at lsr 1 
and 
root@lsr2# mplsadm -A -B -O gen:1234:eth0:ipv4:192.168.5.33 -f192.168.5.33/32
  root@lsr2# mplsadm -A -I gen:2614:0

i don know why im gettin this prob that is

root@localhost root]#

*********Error: either "to" is duplicate, or "lsp" is a garbage.***********

the 0x00000004 key is appropriate as i have followed the doc when it was 
created but the commands mpladm i have mentioned is not a part of the package 
document ......so plzz help me out 

[mpls-linux-general] hi prob

why is this so ????????

[mpls-linux-general] (no subject)

[deepak <dxb...@wi...>]

hi all 
i have compiled and installed MPLS-linux now while testing i saw this problem 
i am using 2 PC's as my LSR's and when i gave these commands i got the 
following output i also have given the same key as i got in the mplsout file 
as shown below but im getting this error that either to is dupli.............
when i give a ip route add commd also how do i test that the traffic is 
following the LSP if this works ofcrs

root@localhost root]# cat /proc/net/mpls_out 
0x00000004 0/0/0 1 PUSH(gen 17) SET(eth0,192.168.6.60)

That's true, but would just braces { .. } be sufficient for that purpose?
