[mpls-linux-general] zebra+ldp

[Zahra F. <mar...@ya...>]

hi all,
I have two PCs with linux8.0
        A---------------------------B
192.168.2.207                  192.168.2.152
I have installed:
1-kernel-2.4.18-27.8.0+mpls1.172.i386.rpm
2-iproute-2.4.7-5+mpls1.172.i386.rpm
3-iptables-1.2.6a-2+mpls1.172.i386.rpm
4-mplsadm2-1.172-2.i386.rpm
5-zebra-0.94-1+ldp0.310.i386.rpm
successfully.
Now I want to setup dynamic LSP via ldp.
At first,I make a clean start:
#ip route flush scope global type unicast
#ip addr flush eth0
and then to create dummy interface on each router, I
do a 'modprobe dummy' from my linux command line and
type 
'ip link show' to check that it is loaded.
Then using zebra cli, I assign address 192.168.0.1/32
to com A, 192.168.0.2/32 to com B, at this point I
dont know if these addresses are correct or not?
and using the OSPF cli, I add a network statement, but
I dont know if it is right or not?
Here are my deamon files:

Zebra.conf:
!
! Zebra configuration saved from vty
!   2003/08/04 04:05:50
!
hostname uml-1
password root
enable password root
service advanced-vty

!
interface dummy0

!
line vty

------------------------------
ospfd.conf:

mplsd.conf:

!

interface lo
 no mpls labelspace
!
interface eth0
 mpls labelspace 0
 mpls ldp
 !
!
interface dummy0
 no mpls labelspace
!
line vty
!
-----------------------------
Then I run the following commands on both computers:
# ./zebra -f /etc/zebra.conf -P 1024 -d
# ./ospfd -f /etc/ospfd.conf -P 1025 -d
# ./mplsd -f /etc/mplsd.conf -P 1026
but when I run the last command, this message appears:
rsvpte_vty_init
there is no such command
Error occured during reading below line
  mpls labelspace 0
So I try to configure it by hand, telnet to port 1026
and login and execute the below commands:

enable
<password>
conf ter
mpls ldp
tr all
exit
int lo
exit
int eth0
mpls ldp
exit
int dummy0
exit
end

uml-mplsd# sho ldp neighbor

        No discovered neighbors

Why "No discovered neighbors" ?

when I caputre the packets with ethereal, both
cmputres only send Hello message to 224.0.0.2
destination, I'm confused,Please help me.
I'm sorry if the letter is too long, but it's very
important for me to solve the problem and setup
dynamic LSP via ldp, I really need your help.
Thanks alot for your time.

Regards,
Z-Farahmand
