Re: [mpls-linux-general] probelm on MPLS testing

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

As Vino and Aditya have said, the setup should work.  We need more info from
you for us to help debug your setup.

A good start is the exact commands you typed in to setup the LSP and FEC
binding.  A dump of your routing table and interface table is also useful.
After you have setup the LSP, dump the contents of /proc/net/mpls_*

Ship all of that info in a e-mail to the list, we should be able to figure
it out from there.
