^^^^^^^ ^^^^
means we recv traffic No no, you want this to say FWD ...
mplsadm2 -I gen:16:0 -O 0x2 -B
will XC gen:16:0 to outlabel with index 0x2
Start with that fix.

You need to type these commands: On A: route add -host 10.0.1.30 gw 10.0.0.20 On C: route add - host 10.0.0.10 gw 10.0.1.20 Normally it should work. Regards. On Tue, 10 Sep 2002, Wayne W.

Hi, Just downloaded, installed and compiled the latest version into the kernel. I am trying to setup two LSPs, one going from A to C and the other going from C back to A in the following simple network, but could not get ping to work from A to C nor from C to A. 10.0.0.10 (eth0) 10.0.1.20 (eth1) A---------------------B---------------------C 10.0.0.20 (eth0) 10.0.1.30 (eth1) The commands issued are as follows, and I have checked /proc/net/mpls* and it seems all the entries are recorded correctly. On A: ===== mplsadm2 -vAO 0 -o push:gen:16:set:eth0:ipv4:10.0.1.30 # returns <key1> ip2 route add 10.0.1.30/32 via 10.0.0.20 lsp <key1> mplsadm2 -vAI gen:20:0 mplsadm2 -vL eth0:0 On B: ===== # for LSP from A to C mplsadm2 -vAI gen:16:0 mplsadm2 -vAO 0 -o push:gen:16:set:eth1:ipv4:10.0.1.30 # returns <key2> mplsadm2 -vI gen:16:0 -o <key2> -B mplsadm2 -vL eth1:0 # for LSP from C to A mplsadm2 -vAI gen:20:0 mplsadm2 -vAO 0 -o push:gen:20:set:eth0:ipv4:10.0.0.10 # returns <key3> mplsadm2 -vI gen:20:0 -o <key3> -B mplsadm2 -vL eth0:0 On C: ===== mplsadm2 -vAI gen:16:0 mplsadm2 -vAO 0 -o push:gen:20:set:eth1:ipv4:10.0.0.10 # returns <key4> ip2 route add 10.0.0.10/32 via 10.0.1.20 lsp <key4> mplsadm2 -vL eth1:0 I have doubled-checked the commands and I believe they are accurate and complete. Any ideas on what could be wrong and suggestions on what to do? Thanks, -Wayne |

Hello, I've tried to install a test bed of MPLS. Up to now all seems to go well (Kernel 2.4.17 & mpls-linux-1.1 's compilation,Labels' add). To know if the flow of the traffic uses mpls protocol, i've setup ethereal in each host of the network. While i ping one host ethereal sniff well all the packets but doesn't display a mpls flag to be sure that it's working.Could someone tell me all the steps to follow in order to filter mpls packet. P.S. For information i think to have well set up all the LSPs'. |

There are differnt paths that achieve this, the most common is by marking routes in the IPv4 FIB as MPLS routes. In this case the link between IP and MPLS is done via 3 steps: -mark routes in the IPv4 FIB with info about which LSP they map to -in IPv4 "slow path code" identifies route lookups that match marked FIB entries and makes a MPLS aware dst_entry -packets are redirected to mpls_output() due to the MPLS aware dst_entry Jim On Sun, Sep 08, 2002 at 06:37:32PM +0530, Anjaneya Pal wrote: > > hi friends, > > i was just going through the mpls code which i had downloaded from > www.sourceforge.net. since mpls works above data-link layer...there must > be some function in the link layer which will be calling an mpls layer > function....can ne'one tell me wht r the two functions? > also plz tell me the two functions used in between ip and the mpls layer. > > thnx in advance > > -- > Anjaneya Pal, > > > Member of Technical Staff, > > > eInfinitus Technologies Pvt.

First suggestion is to get mpls-linux-1.170 ;-) mpls-linux-1.1x changes the way FEC bindings are done. So it's not even worth going through trouble shooting the problem your having on mpls-linux-0.996. Jim On Sat, Sep 07, 2002 at 11:09:06PM -0400, Wayne W.

Hi all, I have four identical PCs running kernel 2.4.8 and I have successfully patched and compiled mpls-linux-0.996 into the kernel on all of them. However I realize that the FEC binding command only works on one of the PCs. For the other PCs, after issuing the command, will not result in a new entry in /proc/net/mpls_fec. So in the current setup, I can only setup one LSP (because FEC binding only works in one PC). I am suspecting that I might have accidentially unchecked some kernel options on those 3 PCs that are required for this mpls package. Any suggestions on what to do? Thaks, -Wayne |

Hi, I could compile linux using kernel 2.5.8 and zebra 0.93a. I could run mplsd and configure it. However I am not able to capture any ldp packet on ethereal. I know there is something wrong with the configuration of mplsd. I am running zebra first, and then mplsd. Is there anything else to do..... Or... Can anyone tell me where to find the documentation on how to configure Mplsd. Thanks, Manish " ZenSar Technologies Ltd.

You can start with mpls-linux and ldp-portable. ldp-portable contains a patch against zebra-0.93a which runs ldp-portable inside the zebra routing environment. Currently there is close relationship between zebra + ldp anf mpls-linux. http://sf.net/projects/mpls-linux/ On Tue, Sep 03, 2002 at 02:16:39PM -0300, Alexandre Carlos de Oliveira wrote: > Hi all, > > Where can i find an implementation of LDP or CR-LDP on linux? > > Regards > > Alex > > > You won't find it as a draft any more .... try RFC3212 :-) > > > > On Mon, Sep 02, 2002 at 11:01:55PM -0700, Paresh Patil wrote: > >> Hi all, > >> > >> I want to do some developement in CR_LDP area.

You are correct in your observation. There are two motivations for the change. First of all the LSR MIB gives us a hint that this is the "correct" way because the key to the outsegment table is a sequential index. Why would the MIB do this though? I believe the main reason for this is the conflict that can occur when running MPLS on an broadcast interface. What would it take to maintain unique keys when we receive multipla label mappings on the same interface with the same label value, but from 2 differnt nexthops? The straight forward answer is: outgoing interface index, outgoing label, and nexthop ip (which could be IPv6!). So instead of trying to hash a 68 bit (or 84 bit!) value, why not just maintain a sequential index :-) (BTW that is my 2nd motivation) Jim On Fri, Aug 30, 2002 at 06:55:03PM -0400, James Li wrote: > Hi Jim, > > I noticed in version 1.16, the radix key for outlabel is changed to a sequential index, vs the old scheme.

This key is returned to the user = land, and expected for a delete operation.=20 What's the motivation behind this change? Now the user land needs to maintain a mapping from label to key. It = sounds better to me, if kernel can take care of that mapping, and allow = label (instead of key) as the input parametre for delete operation. Thanks, James |

I forgot to change the file needed for MPLS + Iptables. So a work around for now is not to configure your kernel with MPLS + Iptables. I will release a new version with a fix.

Hi all,
I have small querry regarding MPLS-LDP implementaion.
In ldp-portable-0.110.tar.gz In the directory doc
there is file ldp_struct.txt that shows various
elements in LDP implementations and relations between
them as shown below.
-----
| |
.------| Adj |
/ | |
---------- / -----
| In Label |-------. 1:1 |
---------- N:M / |
| \ / 1:N
1:N \ / |
| --------- --------
---------- N:1 | | N:1 | | 1:1|
|Out label |<----->| Session |<----->| Entity |<----|
---------- | | | | |
--------- --------
| |
N:M 1:1
| |
------ -----
| | | |
| Addr | | If |
| | | |
------ -----
1. I am not clear about what is 'Entity' in this
diagram.
2. There is little confusion about mappings. Why is
in:out label mapping is 1:n and not n:m.
Regards,
Paresh
