Re: [mpls-linux-general] Problem with ip route + lsp

[Alexandra A. <aa...@te...>]

Hello,

Thanks, now the MPLS-Linux example =
(http://perso.enst.fr/~casellas/mpls-linux/index.html) is working.  But, =
what is the real advantage? where can I apply the mpls? What is the =
sense to have MPLS in to PCs with the same network?

I would like to apply this between two remote linux!.  I Have for =
example two simple tunnel linux servers, each of one in differents =
cities with some routers in the middle, and I can make a vpn without =
ipsec between two remote edge with differents networks.  The only =
disadvantage
is that I can't repeat de networks more than once.  MPLS improve this?, =
and if do; can you help me with some examples?


Thanks for your help.

  Hello,

  I have installed in my linux fedora core 2 the next package:

  iproute-2.4.7-14mpls_1_935
  mplsadm2-1.935-1
  iptables-1.2.9-2.3.1mpls_1_938
  quagga-0.96.4-1.1mpls_1_935
  kernel-sourcecode-2.6.8-1.521mpls_1_938a
  mplsadm2-1.938-1
  kernel-2.6.6-1.435.2.3skas3_mpls_1_935
  iptables-1.2.9-2.3.1mpls_1_935
  iptables-ipv6-1.2.9-2.3.1mpls_1_935
  glibc-kernheaders-2.4-8.44mpls

  After reboot the machine, I tried to configure the example:

  [root@mplsa 1_935]# mplsadm2 -A -O 0
  MPLSADM mplsadm.c:692:main: Out segment input: 0
  Key: 0x00000003
  Out Segment add: Success
  [root@mplsa 1_935]#=20

  [root@mplsa 1_935]# mplsadm2 -O 0x3 -o =
push:gen:16:set:eth0:ipv4:128.104.18.114
  MPLSADM mplsadm.c:692:main: Out segment input: 0x3
  MPLSADM mplsadm.c:688:main: Out instr input: =
push:gen:16:set:eth0:ipv4:128.104.18.114
  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: eth0
  MPLSADM mplsadm.c:182:parse_nh_info: 128.104.18.114
  MPLSADM mplsadm.c:204:parse_nh_info: Nexthop protocol: ipv4
  MPLSADM mplsadm.c:596:fill_instructions: Length: 2
  Out Instr: Success
  You have new mail in /var/spool/mail/root
  [root@mplsa 1_935]#=20

  The problem is HERE:
  [root@mplsa 1_935]# ip route add 128.104.18.114/32 via 128.104.18.114 =
lsp 0x3
  Error: either "to" is duplicate, or "lsp" is a garbage.
  [root@mplsa 1_935]#=20

  Why, I installed iproute-2.4.7-14mpls_1_935, and other version with =
lsp patch without succes?

  Can somebody say to me what is the problem or missconfiguration?

  Thanks
