[mpls-linux-general] ... leaving Las Vegas ...

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

Hey folks,

Sorry for the LOOONNNNGGG silence.  I was at Networld + InterOp Las Vegas
doing MPLS interoperability testing.  I hope to spin through my mail box
this evening answering questions and responding to requests.

Laters,
Jim

Re: [mpls-linux-general] some questions with ldp-linux

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

THis is a know probelm.  I am working on a fix for it.

I received a hint from Luca (his last name escapes me now) that it might
be the policy layer which is to blame.
