[mpls-linux-general] Simple examples, they do not work!

[Jung J. <jj...@hs...>]

Hi!

I have just read the manual and insalled mplsadm2, and iproute.
I have a simple network, like "2. Simle example":

-----------------------------------------------------
Host A:
eth1: 10.120.0.5
---------------
Host B
eth1: 10.120.0.6
-----------------------------------------------------

I would like to set up a manual LSP between them.
(as shown in example 2)

A:
mplsadm2 -AO 0    (out: key1)
mplsadm2 -O key1 -o push:gen:16:set:eth1:ipv4:10.120.0.6
ip route add 10.120.0.6/32 lsp key1
#out:RTNETLINK answers: no such device

what does it mean? what is RTNETLINK?
i think this host can not send
IP packets over mpls :)

mplsadm2 -AI gen:17:0
but can it receive packets?

mplsadm2 -L eth1:0
-----------------------------------------------------
And when I try to set up a tunnel:
(4. MPLS tunnel interfaces)

A:
mplsadm2 -AO 0 -o push:gen:1024:set:eth1:ipv4:10.120.0.6 (out:key2)
mplsadm2 -AT tunnel1
ifconfig tunnel1 10.120.0.5 netmask 255.255.255.255
mplsadm2 -BO key2 -T tunnel1
route add -host 10.120.0.6 tunnel1

and now Host A can send packets to host B
(with ethereal i can see it!!!)
and host B can send packets to Host A

BUT THEY CAN NOT RECEIVE PACKETS, JUST SEND!
(ping between A and B did not work)

what should i do?

regards!
