I think you can convert the EXP bits to tcindex(or nfmark) in the ILM and then in the NHFLE convert from tcindex(or nfmark) back to EXP _before_ each push. Something like this: mplsadm2 -A -I gen:16:0 mplsadm2 -I gen:16:0 -i exp2tc:0:0:1:1:2:2:3:3:4:4:5:5:6:6:7:7:pop:fwd:0x2 where 0x2 is the key for this NHLFE: mplsadm2 -A -O 0 Key: 0x2 mplsadm2 -O 0x2 -o tc2exp:0x3f:0:0:1:1:2:2:3:3:4:4:5:5:6:6:7:7:push:gen:17:tc2exp:0xf:0:0:1:1:2:2:3:3:4:4:5:5:6:6:7:7:push:gen:18:set:eth1:ipv4:1.1.1.1 The result is that in the ILM we store the EXP bits in the tcindex. Then before we push we set the "current EXP bits" based on the tcindex. After every push the "current EXP bits" are cleared. > > But there is no reason why I cannot > > create a flag that allows this sort of operation to occur. > > Would you like this to be a flag on the ILM, on the NHLFE, or > > a global flag? > > Personally I would like to have it done in any way convenient for you. > But the big issue is that we are still using the old version 1.172 > because there is some other linux functionality required not available > in 2.6 kernel.

Personally I would like to have it done in any way convenient for you. But the big issue is that we are still using the old version 1.172 because there is some other linux functionality required not available in 2.6 kernel. Please ignore my request if you have found it inappropriate... Many thanks for your comments... Cheers, Jonathan |

Currently the EXP bits are new for each level of the hierarchy, this is considered the 'best common practice' by those in the MPLS WG at the IETF. At one time we discused the senerio you are talking about, the the general concesus was that it was a bad idea. But there is no reason why I cannot create a flag that allows this sort of operation to occur. Would you like this to be a flag on the ILM, on the NHLFE, or a global flag?

If you installed the new RPMs from my site, then you use the 'spec_nh 0x8847 0x2' syntax, not 'lsp 0x2' On Wed, Aug 11, 2004 at 04:09:28AM +0000, sandeep goyal wrote: > hello friends > please any one can tell me what is the solution to this "ip route " > problem. this is when i use ip route .... > i am not able to rectify it . even i am having iproute mpls rpm installed. > [root@localhost root]# mplsadm2 -A -O 0 > MPLSADM mplsadm.c:692:main: Out segment input: 0 > Key: 0x00000002 > Out Segment add: Success > [root@localhost root]# mplsadm2 -O 0x2 -o > push:gen:13:set:eth1:ipv4:192.168.40.3 > MPLSADM mplsadm.c:692:main: Out segment input: 0x2 > MPLSADM mplsadm.c:688:main: Out instr input: > push:gen:13:set:eth1:ipv4:192.168.40.3 > MPLSADM mplsadm.c:292:fill_instructions: Instruction: push > MPLSADM mplsadm.c:229:fill_label: Label type: gen > MPLSADM mplsadm.c:292:fill_instructions: Instruction: set > MPLSADM mplsadm.c:181:parse_nh_info: eth1 > MPLSADM mplsadm.c:182:parse_nh_info: 192.168.40.3 > MPLSADM mplsadm.c:204:parse_nh_info: Nexthop protocol: ipv4 > MPLSADM mplsadm.c:596:fill_instructions: Length: 2 > Out Instr: Success > [root@localhost root]# ip route add 192.168.40.3/32 via 192.168.40.3 lsp 0x2 > Error: either "to" is duplicate, or "lsp" is a garbage. > [root@localhost root]# ip route add 192.168.40.3/32 lsp 0x2 > Error: either "to" is duplicate, or "lsp" is a garbage. > [root@localhost root]# iproute add 192.168.40.3/32 via 192.168.40.3 lsp 0x2 > bash: iproute: command not found > [root@localhost root]# man ip route > [root@localhost root]# > [root@localhost root]# ip route add 192.168.40.3/32 via 192.168.40.3 lsp 0x2 > Error: either "to" is duplicate, or "lsp" is a garbage. > [root@localhost root]# ip route show > 134.74.228.0/24 dev eth2 scope link > 192.168.30.0/24 dev eth0 scope link > 192.168.40.0/24 dev eth1 scope link > 169.254.0.0/16 dev eth2 scope link > 127.0.0.0/8 dev lo scope link > default via 134.74.228.1 dev eth2 > [root@localhost root]# cat /proc/net/mpls_version > 01010702 > [root@localhost root]# cat /proc/net/mpls_out > 0x00000002 0/0/0 1 > [root@localhost root]# ip route add 192.168.40.3/32 via 192.168.40.3 lsp 0x2 > Error: either "to" is duplicate, or "lsp" is a garbage. > thank you very much in advance > sandeep goyal > ccny,cuny > > _________________________________________________________________ > Get head-hunted by 10,000 recruiters. http://go.msnserver.com/IN/46246.asp > Post your CV on naukri.com today. > > > > ------------------------------------------------------- > SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media > 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 > Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. > http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 > _______________________________________________ > mpls-linux-general mailing list > mpl...@li... > https://lists.sourceforge.net/lists/listinfo/mpls-linux-general -- James R.

What Linux distrubution are you using? The RPMs I've created are specifically meant for a Fedora 2 install. If you want to build a RPM from the SRC RPM you should do a google for 'howto build binary RPM from source RPM' BTW when you install a source RPM it puts the source for the RPM in the redhat/SOURCE directory of your current redhat build tree (if you don't know what I'm talking about, check /usr/src/redhat/SOURCE/) On Mon, Aug 09, 2004 at 05:00:02PM -0700, sandeep goyal wrote: > > hello jleu > hey i am working on the implementation of the quagga on the linux for my project. > > .i tried to run th e rpm quagga-0.96.4-1.1mpls_1_935.i386.rpm .but it has failed dependencies ie. > libc.so.6(GLIBC_2.3.4) is needed by quagga-0.96.4-1.1mpls_1_935.also i tried to use the > glibc-kernheaders-2.4-8.44mpls_1_935.i386.rpm file but it also didnt turn up anything .it jjust give up message glibc-kernelheader-2.4-8.44mpls ,what it means it have created the folder having this name , and if yes than what is the path for that.and is not what is the modification it did.and even after making glib-ker........i386.rpm rpm run.the failed dependancies are not gone.and still quagga-0.96.4-1.1mpls_1_935.i386.rpm give up the failed dependancies message. > > > and when i tried to run > quagga-0.96.4-1.1mpls_1_935.src.rpm it didnt turn up any folder . and it ask for jleu user existance.Is it necessary to have jleu user.but if i didnt it say it is making it for root.so what i have to do next.i mean like i worked on previously on quagga from quagga.net and created zebra.conf,ospfd.conf files and runed them.but here i didnt found any folder created as a result of running the > quagga-0.96.4-1.1mpls_1_935.src.rpm. > finally what is the basic difference between the .rpm files and .src.rpm files available on the website. > > thanks for the answers > > sandeep goyal > > next generation internet lab > > ccny,cuny > > new york ,US > > 201-724-4570 > > __________________________________________________ > Do You Yahoo!? > Tired of spam?

I do you mean that you have installed the RPM for Fedora 2? If so then you can try the simple example I show on http://mpls-linux.sf.net/ Or you can try and run the 'zerbra' daemon and use the zebra CLI. If your not familiar with howto run zebra/quagga head over to quagga.net for more info.

Probably not. I only support quagga. You can try and back port the patch I supply.

Dear all, I would like to dynamically set up the EXP bit of an outgoing label (say 100), and push it into an existing shared MPLS tunnel (say mpls200). That is: For high priority traffic: mplsadm2 -O $opcode -o set_exp:0x5:push:gen:100:set:mpls200:ipv4:192.168.50.1 For best effort traffic: mplsadm2 -O $opcode -o push:gen:100:set:mpls200:ipv4:192.168.50.1 Is there any way to make the outer label (i.e. label representing mpls200) inherit the EXP bit from an inner label? Since we are not doing label swapping, I am not sure if the "expfwd" instruction is the way.=20 Any suggestions/comments are greatly appreciated... Cheers, Jonathan |

hello jleu
hey i am working on the implementation of the quagga on the linux for my project.
.i tried to run th e rpm quagga-0.96.4-1.1mpls_1_935.i386.rpm .but it has failed dependencies ie.
libc.so.6(GLIBC_2.3.4) is needed by quagga-0.96.4-1.1mpls_1_935.also i tried to use the
glibc-kernheaders-2.4-8.44mpls_1_935.i386.rpm file but it also didnt turn up anything .it jjust give up message glibc-kernelheader-2.4-8.44mpls ,what it means it have created the folder having this name , and if yes than what is the path for that.and is not what is the modification it did.and even after making glib-ker........i386.rpm rpm run.the failed dependancies are not gone.and still quagga-0.96.4-1.1mpls_1_935.i386.rpm give up the failed dependancies message.
and when i tried to run
quagga-0.96.4-1.1mpls_1_935.src.rpm it didnt turn up any folder . and it ask for jleu user existance.Is it necessary to have jleu user.but if i didnt it say it is making it for root.so what i have to do next.i mean like i worked on previously on quagga from quagga.net and created zebra.conf,ospfd.conf files and runed them.but here i didnt found any folder created as a result of running the
quagga-0.96.4-1.1mpls_1_935.src.rpm.
finally what is the basic difference between the .rpm files and .src.rpm files available on the website.
thanks for the answers

I am trying to QUEUE packets to the userspace using libipq at my MPLS egress router. But I always get the error message stating "Received error message". Is this because the libipq program requires IP packet but I have QUEUED packet on all the chains and got the same error. Can anyone help me as to why I am getting this error message and how to get rid of it? I am doing the same at the ingress and that works fine. Regards, Muhammad R.

Hello Pim and all, i need suggestion here. I want to make a test between MPLS and Intserv RSVP-TE (with FF style) this is what i used : is_config at all node : ..... #$TC class add dev $i parent 1:1 classid 1:3 cbq rate 8Mbit \ #bandwidth 10Mbit weight 800Kbit prio 5 allot 1514 cell 8 \ #maxburst 20 avpkt 1000 $TC class add dev $i parent 1:1 classid 1:7ffe cbq \ bandwidth 10Mbit \ rate 10Mbit weight 1Mbit prio 5 allot 1514 cell 8 \ maxburst 20 avpkt 1000 isolated bounded done ..... The configuration : host1--||--Ingress--|--4 router--|--Egress--||--host2 I am using rapirecv_auto dan rtest2 -f file. I want to use Intserv with FF style : At Ingress : #cat file 13.13.13.2 11.11.11.1 200 1 0 11.11.11.2:12.12.12.2:0 0 Can i make rsvp-te intserv with FF style by that configuration.... ? In my plan, i want to make FTP and HTTP connection between host1 and host2 (downloading file), while TG will be generate traffic at network between Ingress and Egress as the disturber. Like u see at the is_config file i just creating one parent, is this sufficient to my plan.. ? And when i run ./tunnel -L -c after mapping a traffik to the LSPID, i found that a parameter is BE, is this okay.. ? Sorry i have many question. I really puzzled since there is no comperhensive guide to set up intserv rsvp network. =========================================================================================== Netkuis Instan untuk wilayah Bandung (kode area 022) - SD,SMP,SMA berhadiah total puluhan juta rupiah... periode I dimulai 1 April 2004 =========================================================================================== |

I used the following command on the ingress ip route add 192.168.11.2/32 nexthop via 192.168.12.2 spec_nh 0x8847 0x2 \ nexthop via 192.168.15.2 spec_nh 0x8847 0x3 and got the response as RTNETLINK answers: invalid argument However a similar command executes without any trouble on the egress. When I run the following command on the ingress ip route add 192.168.11.2/32 via 192.168.12.2 spec_nh 0x8847 0x2 it executes without trouble showing that "ip route" command is working. Can you kindly tell me the possible reason for this. |

Therefore it will not make a nexthop unique. If you remove the spc_nh tag from the command you'll see why 'ip' is complaining, your telling it to add the exact same nexthop twice. You cannot do that. You must have, at the very minimum, a different nexthop IP address. This is completly orthoganl to your problem though. You do not need to add the multiple nexthops on 'A'. In my sample config I only had one nexthop specified for the route to 2.2.2.2. The process of assigning packets to the different LSPs is done by the MPLS layer NOT the IPv4 layer. > However a similar command executes without any trouble on the egress.

Configuration on B
------------------
mplsadm2 -L eth1:0
eth1 is connected to A
mplsadm2 -A -I gen:16:0
mplsadm2 -A -O 0
Key: 0x2
mplsadm2 -O 0x2 -o push:gen:16:set:eth2:ipv4:192.168.2.2
mplsadm2 -B -I gen:16:0 -O 0x2
LSP #1 comes in eth1 with label 16 and goes out eth2 with label 16
eth2 is connected to C
mplsadm2 -A -O 0
Key: 0x3
mplsadm2 -O 0x3 -o push:gen:17:set:eth3:ipv4:192.168.3.2
mplsadm2 -A -I gen:17:0
mplsadm2 -B -I gen:17:0 -O 0x3
LSP #2 comes in eth1 with label 17 and goes out eth3 with label 17
eth3 is connected to E
Notice I did not add any routes via 'ip route' nor do I add and filters
via 'iptables'. On B (and C,D,E,F,G) we only label switch no IPv4 route
configuration is required.
If B was going to act as ingress LER (as opposed to LSR) here is how you
would configure the the 2.2.2.2/32 route:
ip route add 2.2.2.2/32 nexthop via 192.168.2.2 spec_nh 0x8847 0x2 \
nexthop via 192.168.3.2 spec_nh 0x8847 0x3
NOTE: that is one big long command that specifies multiple nexthops

I got your point regarding the iptables marking and then using the nffwd. Thank yopu very much for elaborating on that with an example. But what if in the diagram below B is the ingress and one LSP is C->D->G and the other is E- >F->G, i.e, 2 different LSPs on 2 different physical paths headed to the same destination which is H. then I am facing the RTNETLINK problem.
