Hi, I installed the current mpls in linux-2.4.7. Some of the commands as given in the manual work such as ./mpls ai 100 0 30. But ./mpls as 0 30 2 30 doesn't work. It says. AddSwMapping failed: 105 (No buffer space available). What am I missing ? Thanks, Dhiman |

Thanks for the clarifications.
I am still facing problems in setting up a zldp based
network. Here is the configuration I have:
eth0 eth0 eth1 eth0 eth1 eth2 eth0 eth0
------- ------ ------- ------ -------
| Host1 |------| LER1 |-----| Core |----| LER2 |-----| Host2 |
------- ------ ------- ------ -------
150.1.40.2 40.1 | 1.2 2.2 2.1 | 5.2
192.168.1.1 132.10.5.1
I have configured zebra running ospf, rip and bgp on all the routers
along with zebra ldpd. All the routes are properly set, ospf, bgp and
rip are behaving as expected.
Linux kernel is ver - 2.4.5 with mpls_linux patch.
I have zldpd running with the following config files
(I have inherited these conf files from the sample in the
source tree..so I suspect some misconfiguration here)
At LER1:
hostname ldpd
password a
log stdout
interface lo
interface eth0
mpls ip
interface eth1
mpls ldp router-id 192.168.1.1
mpls ip
line vty
(Q: what are these mpls commands and how do they relate to
corrosponding interface commands?)
At Core:
hostname ldpd
password a
log stdout
interface lo
interface eth0
mpls ip
interface eth1
mpls ldp router-id 192.168.1.2
mpls ip
line vty
At LER2:
hostname ldpd
password a
log stdout
interface lo
interface eth0
mpls ip
interface eth2
mpls ldp router-id 192.168.2.1
mpls ip
line vty
zebra_ldp is sending hello packets seemlessly..but I dont see the
neighbour list getting updated as it reports to have not established
sessions. On doing 'show mpls ldp routes' on the ldpd console, I can
see correct routes being shown.
I think I have a fundamental problem in the configuaration.
Is this configuration and enough to setup LSPs?
My next question: I understand that zldpd allocates the labels
and FECs based on the information gathered from Zebra routing
tables, if so, how do I specify my own FEC and LSP. Is my
understanding right?
And, how do I understand the mpls proc files. Is there any pointers to
which I can refer?

Hi, I downloaded the rsvp daemon and added the patches. There are few questions. 1) Do I need to add the mpls patch from sourceforge in addition to the the rsvp-te patch ? 2) When compiling rsvp deamon, it was saying linux/mpls.h not found. I had to put the exact path /usr/src/linux/include/linux and I had also done ln -sf /usr/src/linux-2.4.1 /urs/src/linux 3) While linking the rsvpd, it could not find -lefence in the Makefile option, so I had to compile after commenting that. So, why was the error ? 4) Can we test ldp, ingress mapping so as in sourceforge pkg, by patching only the rsvp patch ? -Dhiman pim...@in... claims the following: > Hi all, > > I guess that some of you might be interested in that fact that we have > released a RSVP daemon for Linux supporting DiffServ over MPLS. > > More information at: > http://ds_mpls.atlantis.rug.ac.be > > Mailinglist: > http://www-lists.atlantis.rug.ac.be/mail_external/listinfo/ds_mpls > > So, if your interested check it out. > > Cheers, > Pim. > > -- > Pim Van Heuven > Ghent University - IMEC > Department of Information Technology (INTEC) > Sint-Pietersnieuwstraat, 41 > B-9000, Gent, Belgium > tel.: +32-(0)9267 3592, secr.: +32-(0)9267 3570 > fax : +32-(0)9267 3599 > e-mail : pim...@in... > WWW : http://www.intec.rug.ac.be > > > > -- Keep America beautiful.

I am using rh7 and linux 2.4.6. I tried to patch and whatever failed I added manually. Where are the definitions of the following in the kernel or iproute patches due to which the kernel is not compiling. 1) where is ECHO defined as used in __PF(ECHO, echo) (iproute patch)? 2) where is "struct mpls_label" defined as used in linux/include/net/mpls.h (kernel patch). -dhiman pim...@in... claims the following: > Hi all, > > I guess that some of you might be interested in that fact that we have > released a RSVP daemon for Linux supporting DiffServ over MPLS. > > More information at: > http://ds_mpls.atlantis.rug.ac.be > > Mailinglist: > http://www-lists.atlantis.rug.ac.be/mail_external/listinfo/ds_mpls > > So, if your interested check it out. > > Cheers, > Pim. > > -- > Pim Van Heuven > Ghent University - IMEC > Department of Information Technology (INTEC) > Sint-Pietersnieuwstraat, 41 > B-9000, Gent, Belgium > tel.: +32-(0)9267 3592, secr.: +32-(0)9267 3570 > fax : +32-(0)9267 3599 > e-mail : pim...@in... > WWW : http://www.intec.rug.ac.be > > > > -- "Somewhere", said Father Vittorini, "did Blake not speak of the Machineries of Joy?

I run ldp_linux on the 3 routers, then on LER B I try to add the route
10.0.1.1/32 via 10.0.3.1 and ldp_linux crashes (see below output with
gdb). My goal is to add 10.0.1.1/32 on LERB, 10.0.4.2/32 on LERA, and
both 10.0.1.1/32 and 10.0.4.2/32 on LSR. If I do so, ldp should establish
the LSPs between 10.0.4.2 and 10.0.1.1, correct ?

All: I am trying to configure zldpd to run according to the configuration mentioned in README. I have zldpd running as daemon along with zebra and ripd. (I am not doing the static route allocation) When I did 'add global' in ldp_linux, it dumps core. Using gdb, it was found that ldp_linux was crashing at: ldp_socket_impl.c:ldp_socket_readlist_del() Here are my questions: Am I doing the right thing running zldpd and ldp_linux together? I assume I need to use mplsadm to specify the FEC bindings and the ldp will do the LSP allocation, is this right? - Praveen |

On 2.4.6 the ARPHRD_MPLS_TUNNEL conflicts with an existing value. Search for *.rej in your kernel source and manually add ARPHRD_MPLS_TUNNEL with a differnt value.

Hi all, I guess that some of you might be interested in that fact that we have released a RSVP daemon for Linux supporting DiffServ over MPLS. More information at: http://ds_mpls.atlantis.rug.ac.be Mailinglist: http://www-lists.atlantis.rug.ac.be/mail_external/listinfo/ds_mpls So, if your interested check it out.

Hi, a quick question about the "route" commands inside the ldp_linux client: I would like to force the client to create the labels manually by using the "add route" command. In other words, I would like to dynamically change the ldp routing information from the client (obviously, this routing onformation will be lost as soon as I exit the client, but I just want to force the label mapping creation and exchange). Is this supposed to be achieved with "add route" ? I tried with a simple example but it does not seem to work.

Hi to all, I wonder if you could help me with the following problem. I have already downloaded the mpls-linux-0.993.tar.gz image. I applied the patch to my kernel (2.4.6). I activated all the necessary fields through make xconfig and tried to compile the new kernel. I got the following results. mpls_tunnel.c: In function `mpls_tunnel_init_gen': mpls_tunnel.c:252: `ARPHRD_MPLS_TUNNEL' undeclared (first use in this function) mpls_tunnel.c:252: (Each undeclared identifier is reported only once mpls_tunnel.c:252: for each function it appears in.) make[3]: *** [mpls_tunnel.o] Error 1 make[3]: Leaving directory `/usr/src/linux-2.4.6/net/mpls' make[2]: *** [first_rule] Error 2 make[2]: Leaving directory `/usr/src/linux-2.4.6/net/mpls' make[1]: *** [_subdir_mpls] Error 2 make[1]: Leaving directory `/usr/src/linux-2.4.6/net' make: *** [_dir_net] Error 2 Any ideas?

Set the compiler to kgcc make CC=kgcc most of the "errors" should go away.

When I try compile ldp_linux this warning ocur: ldp_nortel.h:194:8: warning: extra tokens at end of #endif directive and the compilation stop, to compile I remove option -Werror in Makefile, then the binary is formed, but in compilation a lot warnings ocurr, such as: ldp_label_abort.c:55:3: warning: pasting ""ENTER: "" and ""ldp_label_abort_send"" does not give a valid preprocessing token ldp_label_abort.c:55:3: warning: pasting ""ldp_label_abort_send"" and ""\n"" does not give a valid preprocessing token It can cause problens?

Hi , I am new to this linux networking field . I have background of networking basics . I was going through the MPLS code at sourceforge. I am not able to undersand the way of interfacing to "IP" and ethernet. I am looking for some help where I can get some info how layers are hooked with each other. And how to put our hook of new protocol in those like done here in MPLS code?? I know this is not possible for you busy experts to teach me all but I will be thankfull if you can give any guideline and help. Any URL where I may get some help ? Thanks in advance Surya _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com |

PPP assumes that no protocol packets can flow until a NCP for that protocol has registered and syncronized with the peer. In the case of IPv4 IPCP can negotiate many things (IP addresses, DNS servers ....). In the case of MPLS nothing needs to be negotiated, the only purpose for MPLSCP is to identify that MPLS packet can be sent on this link.

Hi, I have a question regarding MPLS over PPP. What is the expected function of MPLSCP ? Since as per RFC 3032 that is to be sent after NCP then once Network layer negotiations are complete, what will MPLSCP do ? If this is not proper alias for this Q, can you guide me ?

Hi James,
The following is the outcome of Ur suggestion:
U have asked me to try:
( 1) . route add -host 10.1.6.33 gw 10.1.3.28 on LER A
route add -host 10.1.317 gw 10.1.6.17 on LER B
(2). Run gdb on it and tell me where it's crashing.
* This is not clear to me ...... whether I should set some
break points while running " gdb ldp_linux "
and send U the output file ..... also I am not clear what
crashing means ....
( 3). Send me the output from:
show route & show database On each of the LDP speakers.
* I am attaching those files
Also note that No entries are formed in /proc/net/mpls_out and
/proc/net/mpls_fec. Entries in /proc/net/mpls_in
are the same as given earlier.
Hope after going through the files attached U will suggest me accordingly.
Cheers !!!

Hello, Sorry for the delay in responding to this. Unfortunatly the mpls-linux-general mailing list is a closed list, so this had to be approved by the list admin (me) before getting set to the list. You may want to join the mailing list to avoid this in the future: http://lists.sourceforge.net/lists/listinfo/mpls-linux-general On Fri, Jul 13, 2001 at 10:15:30AM +0530, Pradeep wrote: > Hi > I am working on MPLS project.

Your question about how mpls-linux 'communicates with the Layer-2 and layer-3' is a little too general. I'd be more then happy to answer more specific questions. Jim -- James R. Leu |

Hi James,
We have configured 3 machines as follows :
10.1.3.17 eth1 10.1.3.28 10.1.6.33
-------- ------- ------
| LER A |-------| LSR |---------| LER B |
-------- ------- ------
eth0 eth0 eth0
10.1.6.17
The following is the configuration :
At LER A:
route add 10.1.6.33/32 gw 10.1.3.28
add global 10.1.3.17
add interface eth0
At Ler B :
route add 10.1.3.17/32 gw 10.1.6.17
add global 10.1.6.33
add interface eth0
At LSR :
add global 10.1.3.28
add interface eth0
add interface eth1
The following are the results ( outcomes ) :
1. In /proc/net/mpls_in
At LER A:
40004000 gen 16 0 POP DLV
40004400 gen 17 0 POP DLV
40004800 gen 18 0 POP DLV
At LER B :
40004000 gen 16 0 POP DLV
40004400 gen 17 0 POP DLV
40004800 gen 18 0 POP DLV
At LSR :
40004000 gen 16 0 POP DLV
40004400 gen 17 0 POP DLV
40004800 gen 18 0 POP DLV
40004c00 gen 19 0 POP DLV
40005000 gen 20 0 POP DLV
40005400 gen 21 0 POP DLV
40005800 gen 22 0 POP DLV
40005c00 gen 23 0 POP DLV
2. No entries are formed in /proc/net/mpls_out and /proc/net/mpls_fec.
3. In addition to the configuration made at LSR if I give
add global 10.1.6.17 there is an error " Segmentation Fault ( core dumped )".
Can U tell me why this is happening?
Hope somebody can help me in giving the configuration details for the above if I am wrong.
With best regards

Hi,
I can't get any labelled packets out of my atm interface. I'm using a 2.4.6
kernel and the mpls distribution 0.993.
Here's what I do:
# atmarpd -b
atmarpd:ARPD: Linux ATM ARP, version 0.78
atmarpd:IO: SVCs are not available
# atmarp -c atm0
# /sbin/ifconfig atm0 192.168.0.1 up
# mplsadm -A -B -O atm:0/50:atm0 -f 192.168.0.3/32
I seem to get the label created, but no FEC:
# cat /proc/net/mpls_out
80320003 PUSH(atm 0/50) SET(atm0)
# cat /proc/net/mpls_fec
#
Am I doing anything obviously wrong? Anybody any ideas?
Peter.
