RE: [mpls-linux-general] Egress Router, how?

[T. T. <t_t...@ho...>]

Hi.

I have a similar problem.
I have executed "MPLS Hierarchy" in README and succeeded to setup 200 and 
202 LSP.

                 101
    200        201       202
A------B------C------D

But, I had a problem at "On C" setting about 101 and 201. The command is

 # mplsadm2 -I gen:101:0 -i pop:peek
 In Instr: No such device or address

It didn't seem to be set properly.
When I have executed "mplsadm2 -d", the output of the above command is

mpls_set_in_label_instructions: enter
mpls_in_info_hold: enter
mpls_in_info_hold: new count 2
mpls_in_info_hold: exit
mpls_instruction_build: enter
mpls_instruction_build: exit(2)
mpls_instruction_clear: enter
mpls_instruction_clear: exit
mpls_in_info_release: enter
mpls_in_info_release: new count 1
mpls_in_info_release: exit
mpls_set_in_label_structions: exit

What should I do?
I hope any help.

[T. T. <t_t...@ho...>]

Mr. Leu

Thanks for your quick reply.

I have reset LSPs on C as following.

# mplsadm2 -L eth1:0
# mplsadm2 -A -I gen:101:0
# mplsadm2 -A -I gen:201:0
# mplsadm2 -I gen:101:0 -i pop:peek
In Instr: No such device or address

But they seemed to be set properly except the last command again.
How should I do this?

The information of the machine is

  OS : Redhat 8.0
  kernel : 2.4.22
  mpls : mpls-linux-1.172

If you could take a few minutes to answer my question, I would really 
appreciate it.

Best regards

Hmm.  I just excuted the above commands on 1.930 (on a 2.6.1 kernel) and
it works fine.  Obviously something must have changed since 1.172 and 1.930.
I do not have a 2.4 kernel to test on.  I will try and build a 2.4 environment
to test and debug on.

My gut response is to tell you to upgrade to 1.930 (which is based on a
2.6 kernel).

Hello.

I have tried to update.

I executed the following command, but I didn't succeed.

[James R. L. <jl...@mi...>]

What makes you think your .config from 2.4.18 will work on a 2.6.1 kernel?
Make sure to that MPLS is not a module.

Here is how I do it:

on C
----
mplsadm2 -A -I gen:101:0
mplsadm2 -A -I gen:201:0
mplsadm2 -I gen:101:0 -i pop:peek

on B
----
mplsadm2 -A -O 0
mplsadm2 -O 0x2 -o push:gen:101:set:eth1:192.169.1.2
mplsadm2 -A -O 0
mplsadm2 -O 0x3 -o push:gen:201:fwd:0x2
mplsadm2 -A -I gen:200:0
