James,
I took your latest ldp-portable and quagga-mpls, as of now(10/16/2006), from
your perforce depot and rebuilt quagga and ldpd successfully.
I am able to run zebra, ospfd, and the ldpd with your latest changes. I am
using the 2.6.14-1.1644_FC4mpls_1.950b kernel.
I have previously successfully used ospfd/quagga with AND without your MPLS
before.
I want to use LDP or RSVP-TE to detect a link outage and do an automatic
reroute of its traffic over a different link by dynamically rerouting an LSP
or by dynamically putting traffic on a different LSP carried on a good
alternate link(Link Protection). Does your latest LDP provide this
capability? I notice that in my LDP log file, I get a message "LDP:
Interface[eth0] state update" when I pull/replace the eth0 cable, so it must
detect link out. Do you know what mechanism it uses to detect link out and
how quickly (in milliseconds) it can detect link out?
I can't figure out how to use your LDP for this. I have looked at the help
information in the mpls program and the help information for all of the
telnet CLIs for the zebra, ospfd, and ldpd daemons. I've also read all of
the README type text files under the various directories. Some of them are
confusing as it appears they have information for items no longer used, as
one example, mplsd.
On your http://mpls-linux.sourceforge.net/ welcome web page change of
7-14-2006, you stated "there exists a new RSVP-TE implementation for quagga,
we're working on integrating it with mpls-linux". Which RSVP-TE
implementation is this? Will it provide the link protection capabilities I
am looking for?
I am willing to help test, fix, and program LDP and/or RSVP-TE if you would
like.
Also, I have tried Adrian Popa's method for link protection. It works quite
well but I would like to use LDP or RSVP-TE for this as I am hoping to get
quicker link failure detection and traffic reroute times. What would you
expect reroute times using LDP or RSVP-TE for link protection?
Thanks in advance and thanks for producing and maintaining mpls-linux.

Subject: [mpls-linux-devel] ldp-portable update
Just a quick note to anyone who is working with LDP portable and
quagga-mpls from my development tree, you will want to update your
ldp-portable and quagga-mpls trees.
I have been doing some significant bug hunting that fixes many
of the outstanding issues with quagga-mpls and it's use of ldp-portable.
