I've added tommy <ema...@fr...> to the CC list because he is seeing =
the
same issues as you are Gonzalo.
So it looks like configuring the interfaces via vtysh had no affect. The
last thing that differs between your setup and mine is the kernel.
I assume your using fedora. Are you using fedora 4? If so I will
try building an up-to-date FC4 kernel with the latest patches.
(tommy what kernel and distribution are you using?)
In the meantime. Lets dig into the zebra/kernel communication a little bit.
Here is the debugging I have configured:
log file /var/log/monkey2
debug zebra kernel
In addition lets try a very controlled test and see is that yields a
difference result:
- Add the above config to your LERs
- Remove all MPLS/LDP commands from the config
- Save the configs
- Stop the OSPF/LDP/zebra daemons
- Clean out all MPLS entities with the 'mpls' utility
- Restart the OSPF/LDP/zebra daemons
- Wait for OSPF to converge
- Add the MPLS/LDP config
Once LDP establishes, send me the result of the show commands, and the
relevant output from the log file you configure. (preferably different log
files for each node)
Hopefully this will help me figure out where the problem is occurring.
