[mpls-linux-general] Problem with Ethernet over MPLS example

[Dunc <dun...@th...>]

Hi everyone,

Firstly, I'm new to MPLS, I'm having a go with mpls-linux to try and get 
the concepts firmly in my head.

I'm also new to Fedora, but have experience with Linux for many years, 
and using the Fedora packages seemed like the easiest way to get a 
working system.


I'm trying out the first example, "Ethernet over MPLS example for 
mpls-linux-1.95x 
<http://sf.net/docman/display_doc.php?docid=31115&group_id=15443>"

Everything looks good until I get to the ebtables line......

[root@MPLS-LER-1 ~]# brctl addbr br0
[root@MPLS-LER-1 ~]# brctl addif br0 eth3
[root@MPLS-LER-1 ~]# ip link set eth3 up
[root@MPLS-LER-1 ~]# ip link set br0 up
[root@MPLS-LER-1 ~]# mpls nhlfe add key 0 instructions push gen 1000 
nexthop eth4 ipv4 172.16.0.3
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
         (0 bytes, 0 pkts)
[root@MPLS-LER-1 ~]# ebtables -t nat -A PREROUTING -i eth3 -j mpls 
--nhlfe 0x2
The kernel doesn't support a certain ebtables extension, consider 
recompiling your kernel or insmod the extension.
[root@MPLS-LER-1 ~]#


Now, I'm sure I have an MPLS enabled kernel:-

[root@MPLS-LER-1 ~]# uname -a
Linux MPLS-LER-1 2.6.23.9-85.fc8.mpls.1.959 #1 SMP Thu Jan 17 01:14:18 
EST 2008 i686 i686 i386 GNU/Linux

[root@MPLS-LER-1 ~]# cat /proc/sys/net/mpls/debug
1

.... and the correct version of ebtables:-

[root@MPLS-LER-1 ~]# yum info ebtables
Installed Packages
Name   : ebtables
Arch   : i386
Version: 2.0.8
Release: 3.fc8.mpls.1.959
Size   : 203 k
Repo   : installed

....and have got these modules loaded:-

[root@MPLS-LER-1 ~]# lsmod | grep eb
ebt_mpls                6209  0
ebtable_nat             6081  0
ebtables               19905  2 ebt_mpls,ebtable_nat




When trying the ebtables line, this is what I get in dmesg:-


[root@MPLS-LER-1 ~]# dmesg | tail -n 1
mpls: unable to find ETH_P_ALL driver
[root@MPLS-LER-1 ~]#


Can anyone tell me where I'm going wrong, or even just point me in the 
right direction?

Thanks in advance,

Dunc
