Hi! I have just read the manual and insalled mplsadm2, and iproute. I have a simple network, like "2. Simle example": ----------------------------------------------------- Host A: eth1: 10.120.0.5 --------------- Host B eth1: 10.120.0.6 ----------------------------------------------------- I would like to set up a manual LSP between them. (as shown in example 2) A: mplsadm2 -AO 0 (out: key1) mplsadm2 -O key1 -o push:gen:16:set:eth1:ipv4:10.120.0.6 ip route add 10.120.0.6/32 lsp key1 #out:RTNETLINK answers: no such device what does it mean? what is RTNETLINK? i think this host can not send IP packets over mpls :) mplsadm2 -AI gen:17:0 but can it receive packets? mplsadm2 -L eth1:0 ----------------------------------------------------- And when I try to set up a tunnel: (4. MPLS tunnel interfaces) A: mplsadm2 -AO 0 -o push:gen:1024:set:eth1:ipv4:10.120.0.6 (out:key2) mplsadm2 -AT tunnel1 ifconfig tunnel1 10.120.0.5 netmask 255.255.255.255 mplsadm2 -BO key2 -T tunnel1 route add -host 10.120.0.6 tunnel1 and now Host A can send packets to host B (with ethereal i can see it!!!) and host B can send packets to Host A BUT THEY CAN NOT RECEIVE PACKETS, JUST SEND! (ping between A and B did not work) what should i do? regards! jj |

You should look into using user-mode-linux. With it I'm able to run a 6 node network on my laptop. http://user-mode-linux.sf.net/ On Fri, Jan 23, 2004 at 01:08:00AM -0800, Natz V wrote: > Hi Guys > > > Through the UI, can I check whether its possible to loopback and have two sessions in the same machine communicating with each other... > > Thank you in Advance > > LDP kid > > > > --------------------------------- > Do you Yahoo!? > Yahoo!

Hai ,

A --- B --- C
192.168.1.2/32 In Tag 20 outTag - 20

In my patch quest, I try to patch zebra 0.94 but it failed. I try to manually have thing working but things like ospf were particulary badly patched. I've got almost the same problem with iproute2. Could someone point me to a documentation where I can find how to compile this two elements ? Thanks in advance, --=20 Eric Leblond <ele...@in...> Alphalink |

I will let James answer this question in detail. I don't relly know if it is production ready or not. I have been using it for some time and it looks quite solid, but there are some issues: a) when using RSVPD it is much less stable. I have ot investigated if it is a kernel issue or a daemon issues and b) during our work to port to 2.6 we have identified some leaks in error paths that have not been backported to 2.4 (references that are not released after a mem alloc fails etc). Maybe someone with more experience may give you a better answer. Regards, R. |

You should get the lastest version of ldp-portable from the P4 repository. Check out http://mpls-linux.sf.net/ for more info on how to get the latest code from the P4 repository.

started zebra. When i started zebra it is crashing. So I first started

Hi Ramon, I guess this is the first email on that list? I am not even sure if i am on it or not. I sent a design description to James last week and was hoping to receive some feedback. Are you guys discussing in the background?

Hi James/Jamal/Harald/all, Well, yet another experimental release. BIG FAT WARNING: ===================== The kernel compiles and boots. proc entries are created and show the mpls subsystem status, tunnels can be created, and netlink "link layer" is set up ,but the user plane (forwarding) implementation does not work (most notably, it is impossible to add MOIs, given the latest changes in dst/neigh/etc.). Although ioctls are enabled for debug purposes, work is in progress to port to netlink (we need to define the MPLS kernel-userspace protocol, but a first step would be to re-use the existing ioctl data structures). I have (non-officially!) #define'd MPLS_NETLINK 9. Maybe the big guys from netdev@ can allocate a number for us :) Regards, Ramon // ------------------------------------------------------------------- // Ramon Casellas - GET/ENST/INFRES/RHD/A508 - cas...@in...

Hi. I can do "make" by replacing /usr/src/linux/include/linux/in.h with /usr/include/linux/in.h, and I can do "ip route add 192.168.1.20/32 via 192.168.1.20 lsp 0x2" by replacing /sbin/ip with /usr/src/mpls-linux-1.1/patches/iproute2/ip/ip. I can see "192.168.1.20 via 192.168.1.20 dev eth0 lsp 0x2. by "ip route show". Thank you for advising me! May I ask you some questions ? -Should I check the "Network packet filtering" and "IP tables support" when I do "make menuconfig", if I use "iproute2" with MPLS-linux? -What differences are there between "mpls-linux-general" ml and "mpls-linux-devel" ml ? I'm looking forward to any reply.

Hi. I don't think that iproute2-2.4.7-now-ss010824 and kernel-2.4.22 go together. Please tell me which versions of iproute2, linux-kernel and Redhat do you use.

Hi. I downloaded iproute2-2.4.7-now-ss010824.tar.gz, and installed it as following; # cd /usr/src/mpls-linux-1.1/patches # tar xzvf iproute2-2.4.7-now-ss010824.tar.gz # cd iproute2 # patch -p1 < ../iproute2-mpls.diff # make But, I have a error in ll_map.c:19. There is a problem about 'gr_group' type at /usr/src/linux/include/linux/in.h:140. The compile ended with the messages as following. make[1]: *** [ll_map.o] error 1 make[1]: out directory '/usr/src/mpls-linux-1.1/patches/iproute2/lib' make: *** [all] error2 Besides, I set "# export CFLAGS="-l /usr/src/linux/include"". But, I didn't any change. I need some solusions.
