Hello James,
I am testing the new MPLS and LDP + Zebra and there=B4s a seg fault =

This is not a restriction makde by MPLS, but a restriction made by the IPv4 stack. It needs the outgoing interface so it can figure out the source address to use on locally originated packets that use this route entry.

Hello, First, I'm sorry if this question has already been answered. Mailing list archives seem to be down for hours now... strange. I've patched stock 2.4.19 kernel with the following options enabled: MPLS, network packet filtering, IP tables support (packet mangling, MPLS target support). I've compiled mplsadm with no problems. I've patched iproute2-2.4.7-now-ss020116 without any problems. Now, the problem is (same problem with another iproute2 version): when trying mplsadm -A -O 0 -o push:gen:16:set:eth0:ipv4:128.104.18.114 (returns key 0x02 for example, which is also in /proc/net/mpls_out) ip route add 128.104.18.114/32 lsp 0x02 I got RTNETLINK: no such device. What's the problem? Kernel or iproute2? Thanks a lot. O.D. _________________________________________________________________ MSN Messenger : discutez en direct avec vos amis ! http://www.msn.fr/msger/default.asp |

Hi all, I'm trying to set up a network to test first intserv/rsvp and then mpls features. Not to have to change the my configuration, I'm using linux-mpls + rsvpd-TE deamon (from Ghent University). My network is very simple : 2 hosts (clients) connected to a central router. I've succeeded in making the software work with kernel 2.4.17 (and rsvpd 0.63) but things seems not that simple with a kernel 2.4.19 configuration. I've compiled this kernel on a development machine and installed it on my the hosts. There is no problem to make the client work but I cannot have the router start correctly. It's boot process is ok but there are some problems with the network services. The only noticeable differences between the router and the hosts are the number of eth accesses (4 instead of 1) and the use of zebra (version 0.92a) on this machine. It seems that zebra doesn't start and dmesg log contains plenty of "mpls_bogus_output" (see bellow). Did anybody heard about such problems ? Thanks :) Eric PS : dmesg log : ... parport0: PC-style at 0x378 [PCSPP,TRISTATE,EPP] eepro100.c:v1.09j-t 9/29/99 Donald Becker http://www.scyld.com/network/eepro100.htmleepro100.c: $Revision: 1.36 $ 2000/11/17 Modified by Andrey V.

Make sure you are running a MPLS enabled kernel. grep for MPLS in the output of the kernel boot message. If you do not find MPLS in the boot message, you're not running a MPLS kernel.

If your are an experienced programmer you can look at the contents of net/netsysm.c.rej and try to hand apply the change to net/netsysm.c. If you don't feel confident in doing this then double check your kernel version and mpls-linux version. The best combination to use: -linux 2.4.19 (not from a distribution package, they add stuff to the kernel source they distribute) -mpls-linux-1.170 > > what is the problem?? > thx > > > > ------------------------------------------------------- > This sf.net email is sponsored by: Are you worried about > your web server security?

Hi James, In my mpls topology, I am trying to measure the protection switching time. For this I want to timestamp the first packate as soon as it is sent through a perticular outgoing interface. How can this be done at easiest and quickest way? Thanks, Nitin __________________________________________________ Do you Yahoo!?

If you want to create static LPS, then all you need is mpls-linux (and the source for iproute2 and/or iptables) If you want to use LDP to setup LSPs then you will need to the ldp-portable package (and the source to zebra-0.93a). > any link where i can get the process of instaling the MPLS_LINUX patch&ldp > portable downloaded from sourceforge it would be of grrt help > thx Start by reading QUICK.START from the mpls-linux-1.170 package. -- James R.

hi im new to this field and i want to install the mpls-linux patch from source forge.net do i need any more software other than ldp portable and MPLS-linux to achieve MPLS capabilities of the linux box....and also if u can provide me any link where i can get the process of instaling the MPLS_LINUX patch&ldp portable downloaded from sourceforge it would be of grrt help thx |

The only reason the user->kernel config is done via ioctls vs netlink is because of ease of implementation. At some point (when I have time) I will convert it back to using netlink (yes back, mpls-linux-1.0 used netlink for user->kernel comunication).

Hi Jim, I have a design question about the Linux MPLS code. Why are the inlabels outlabel and the mapping between those set via usual ioctl? Is there a special reason for not using the netlink socket? Kind regards Georg Klug |

Hi all,
The following patch fixes my symptons, but I am not sure whether this
would be the right place and the right conditions und what the
do_mpls_labelspace() function is called. Probably there need a few flags
to be checked?!?

Hi all,
today I tried sending of labeled packets between adjancent nodes. But
I was facing the kernel message:
"mpls_rcv: MPLS unicast packet recv on interface w/o a labelspace"
I checked that the labelspace needs to be enabled by the LDP during the
do_mpls_labelspace() function. But do_mpls_labelspace() only works if the
ifindex is set correctly. Anyway the function do_mpls_labelspace() is onl=
y
called during config file reading, but the interface data is get afterwar=
ds
when reading the zebra data (after the config file read is done compeltel=
y).
What do you think? Probably I am doing something wrong in teh config file=
?
For your reference I am attaching the mplsd.conf file as well as the
gdb session output:

If you have compiled it with netlink the routes should already have the label binding done. To see if LDP has exchanged labels for routes, check the output of 'show ip route' from the zebra daemon. Then check the output of 'ip route show' (this is the ip from a MPLS patched iproute2). If the output from zebra doesn't show LSP info, then check your OSPF and LDP config. If the output from 'ip' doesn show LSP info, then make sure you've compiled zebra with netlink support.

Hello People, I have successfully installed LDP + Zebra and they are now exchaning = routes with labels... What do I need to do the real labelling of packets in the ingress node? Does MPLS-patched iproute2 label the packets in the ingress node with = zebra+ldp automatically? Pl=EDnio de Paula UNICAMP/Brazil |

Hi James,
I remember that some time back you mentioned that
mpls-patch works with user-mode-linux. Does it
support DiffServ features of MPLS and zebra. Is there
any limitation of mpls in this.
Thanks,
Nitin
Note: I posted this message yesterday, but it seems
that it rebounded back so I am posting agian.
