Hi, all I had some problem in using MPLS-Linux, which NOT solved in general mail list. What is the the process of applying the mpls label to IP packet, or in which function? ip_route_input -> ip_route_input_slow -> ip_mkroute_input -> __mkroute_input -> rt_set_nexthop -> mpls_set_nexthop? -> mpls_set_nexthop2 ? -> mpls_switch ? -> mpls_output2 ? -> mpls_send ? And follow is the problem what I had post in general mail list ================================================ Date: Wed, 23 Apr 2008 13:04:15 +0300 From: adr...@gm... To: orp...@ms...

If the instruction list contains PUSH, then mpls_push() is called and the label is pushed on to the packet. If you enable debugging (echo 1 > /proc/net/mpls/debug) then you will see in the kernel log the calls to the various functions. > And follow is the problem what I had post in general mail list > ================================================ > Date: Wed, 23 Apr 2008 13:04:15 +0300 > From: adr...@gm... > To: orp...@ms... > Subject: Re: [mpls-linux-general] Does mpls-linux support for add label to normal IP packet? > CC: mpl...@li... > > It seems that no traffic passes through nhlfe 0x03.

Hi all.
Thank you for help.
I patch the quagga-mpls.diff to quagga-0.99.6 and configure && make it.
BUT I found that when I telnet to the shell of zebra, ldpd will crash and can not start again.
If I start ldpd and ospfd, telnet any are ok.
But I start zebra after above two, and telnet to 2601(zebra's shell port), ldpd crashed.
The strace of start ldpd again is follow:

You must start zebra before ospfd or ldpd. Also make sure you start
with an 'empty' ldpd config (just hostname and interfaces) there is a
bug with ldpd (which is fixed in the development tree), that is does not
start if there is an existing config.

Thank you for help. I'll try again. BUT, I don't found the file /proc/net/mpls/debug, there is only one file in /proc/net named mpls.

Hi all: I found that the packet which from ip stack to mpls stack in the ip_finish_output2 had passed POSTROUTING hook in netfilter. BUT the packet from mpls stack to ip stack just use neighbour->output, which NOT hook in PREROUTING in netfilter. In this way, if I do SNAT for ip packet and send into mpls stack, will NOT do Un-SNAT for the reply packet. Is my understand right? How to solved it? _________________________________________________________________ 用手机MSN聊天写邮件看空间，无限沟通，分享精彩！ http://mobile.msn.com.cn/ |

Hmm. I think you are looking at the PHP code. Take a look at the 'deliver' instruction. It will show you that packets destined from IPv4 may be configured to go through 'ip_rcv' which will result in the packet travesing all of the IPv4 netfilter hooks.

I just follow the example in the ldp-portable readme.
____________________________________________________ldpd config____________________________________
hostname uml-2-mpls
password root
enable password root
!
mpls ldp
!
interface lo
!
interface eth0
!
interface eth1
mpls ip
!
interface eth2
mpls ip
!
interface eth3
mpls ip
!
interface dummy0
!
line vty
exec-timeout 0 0
----------------------------------------------------------------------------------------------
BUT crash and can not start again.
Follow your last mail, I change the config to the below
-----------------------------------------------------------------------------------------------
!
hostname uml-1
password root
enable password root
!
interface eth0
mpls ip
!
interface eth1
!
interface eth2
!
interface lo
!
line vty
!
------------------------------------------------------------------------------------------------
And ldpd can start, telnet ldpd shell " en, conf t, mpls ldp " to active LDP instance. It seems OK.
BUT if I write to save the running-config, ldpd can not start again.
How to solved it? Is only to start ldpd by telnet on each system boot?
Where is the development tree I can fetch?
==========================================
localhost zenki # p4 client
Perforce client error:
Connect to server failed; check $P4PORT.
TCP connect to p4.dangermen.com failed.
p4.dangermen.com: host unknown.

I was follow the example of "IPv4 over MPLS: two LER example for mpls-linux-1.95x".

Just to make sure I understand what you're trying to do: You want to get hooked into the PREROUTE netfilter chain for packets coming to a LER from MPLS. To do this the normal 'pop peek' instructions should work just. If you want to 'force' the trasistion from MPLS to IPv4 for packets coming to a LER from MPLS you can use the 'deliver' instruction on the associated ILM.

I found another problem.
I can not add ip r for mpls by ssh connect.
______________________________________________________________________________________________
-bash-3.2# ip r
172.16.0.0/24 dev eth1 src 172.16.0.2
192.168.0.0/24 dev eth0 src 192.168.0.2
-bash-3.2# cat /etc/init.d/mpls
#!/bin/ash
modprobe mpls4
mpls nhlfe add key 0 instructions push gen 1000 nexthop eth1 ipv4 172.16.0.3
ip route add 10.0.0.2/32 via 172.16.0.3 mpls 0x2
mpls labelspace set dev eth1 labelspace 0
mpls ilm add label gen 2000 labelspace 0
mpls nhlfe add key 0 instructions nexthop eth0 ipv4 192.168.0.1
mpls xc add ilm_label gen 2000 ilm_labelspace 0 nhlfe_key 0x3
-bash-3.2# sh /etc/init.d/mpls
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
(0 bytes, 0 pkts)
ip: either "to" is duplicate, or "mpls" is garbage
NHLFE entry key 0x00000003 mtu 0 propagate_ttl
(0 bytes, 0 pkts)
-bash-3.2# ip r
172.16.0.0/24 dev eth1 src 172.16.0.2
192.168.0.0/24 dev eth0 src 192.168.0.2
-bash-3.2# ip r add 10.0.0.2/32 via 172.16.0.3 mpls 0x2
ip: either "to" is duplicate, or "mpls" is garbage
-----------------------------------------------------------------------------------------------------------------------
And when I input the last command by keyboard with connect to the mpls machine.
I also can not found mpls keywords on ssh shell.
-bash-3.2# ip r
10.0.0.2 via 172.16.0.3 dev eth1
172.16.0.0/24 dev eth1 src 172.16.0.2
192.168.0.0/24 dev eth0 src 192.168.0.2

I'm sorry for my poor english.
Just like the follow instance.
< Client Router>-------| LER |--------{ MPLS NETWORK }
The packet from Client got into MPLS NETWORK, will through 'ip_rcv, ip_rcv_finish (ip_route_input ip_route_input_slow ip_mkroute_input __mkroute_input rt_set_nexthop mpls_set_nexthop mpl_set_nexthop2) ip_forward ip_forward_finish ip_output ip_finish_output ip_finish_output2 mpls_output mpls_output_shim mpls_output2 mpls_send'. Am I right?
And the packet from MPLS NETWORK to client, will through 'mpls_skb_recv mpls_input mpls_switch mpls_output2 mpls_send neighbour->output'.
If I want to the packet out from mpls_send got into ip_rcv ......, how to config it?
"mpls nhlfe add key 0 instruction pop nexthop ethX ipv4 (Client Router's IP)"? Right?

This is a PHP config, IE no IPv4 route lookup is being done on the LER
when the packet goes from MPLS to IPv4.
For the packet to go through the IPv4 stack you will want your
ILM to be something like:
mpls ilm add label gen 200 labelspace 0
That is it. The default instruction on a ILM are "pop peek".
Which results in mpls_input() returning MPLS_RESULT_DLV which
ends up with the packet being handle via the IPv4 protocol driver's
(net/ipv4/mpls4.c) local_deliver function.

Thank you first.
I was follow the example "IPv4 over MPLS: two LER example for mpls-linux-1.95x".
And had follow config.
________________________________________________________________________________________________

__________________________________________________________________________________________________
HOST A
------
ip route add 10.0.0.2/32 via 192.168.0.2 src 10.0.0.1
LER1
-----
mpls nhlfe add key 0 instructions push gen 1000 nexthop eth2 ipv4 172.16.0.3
(returns key 0x2)
ip route add 10.0.0.2/32 via 172.16.0.3 mpls 0x2

mpls xc add ilm_label gen 2000 ilm_labelspace 0 nhlfe_key 0x3

HOST B

ip route add 10.0.0.1/32 via 192.168.1.3 src 10.0.0.2
_________________________________________________________________________________________________________________
BUT, the packet from HOST A to HOST B does not through the IP stack on LER2.
Is't my config error?
And another problem for quagga, that the patch file quagga-mpls.diff can not patch to quagga-0.99.9 (latest unstable release) or quagga-0.98.6 (latest stable release).
Do you have the new patch file?
Thank you for help.
