[mpls-linux-devel] QUAGGA 99.6 + LDP-Portable

[<gsr...@al...>]

Hi James:

You'll have to forgive me, I had some important business to finish =
before christmas.

I've downloaded the latest quagga-mpls and ldp-portable from your P4 =
repository and

test it in a simple scenario with two PCs.

And these are the versions of the RPMs related to MPLS and QUAGGA and =
the modules I load:

11.0.0.0/24 dev eth0 proto kernel scope link src 11.0.0.1

13.0.0.0/24 via 10.0.0.1 dev eth1 proto zebra metric 20

The result is that, althaugh the NHLFE and ILM tables add a new entry =
for 10.0.0.0/24 subnet,=20

I'm not able to send labeled packets from one host to another because IP =
table doesn't change=20

to route the packets via mpls.

I think we're very close to solve it, but I need your help.

Thanks in advange,
