Hi james,
Thanks alot for your help,
I did all of you said step by step:
at first remove all routes and interfaces addresses on
both machines:
[root@laleh root]# ip route flush scope global type
unicast
[root@laleh root]# ip addr flush eth0
are these command are enough?
I started zebra,ospf and mplsd on each machine:
on comp A(192.168.2.207)
[root@laleh sbin]# ./zebra -f /etc/zebra.conf -P 1024
-d
[root@laleh sbin]# ./ospfd -f /etc/ospfd.conf -P 1025
-d
[root@laleh sbin]# ./mplsd -f /etc/mplsd.conf -P 1026

I telnet to zebra, ospf and mplsd for each machine.
In zebra I did a 'show ip route' and 'show router-id'
on each machine:
on comp A:
uml-1# sho ip route
Codes: K - kernel route, C - connected, S - static, R
- RIP, O - OSPF,
B - BGP, > - selected route, * - FIB route
K * 127.0.0.0/8 is directly connected, lo
C>* 127.0.0.0/8 is directly connected, lo
C>* 192.168.2.0/24 is directly connected, eth0
O 192.168.50.1/32 [110/10] is directly connected,
dummy0, 00:01:00
C>* 192.168.50.1/32 is directly connected, dummy0
uml-1# sho router-id
router-id: 192.168.50.1
on comp B:
uml-1# sho ip route
Codes: K - kernel route, C - connected, S - static, R
- RIP, O - OSPF,
B - BGP, > - selected route, * - FIB route
K * 127.0.0.0/8 is directly connected, lo
C>* 127.0.0.0/8 is directly connected, lo
C>* 192.168.2.0/24 is directly connected, eth0
O 192.168.50.3/32 [110/10] is directly connected,
dummy0, 00:02:15
C>* 192.168.50.3/32 is directly connected, dummy0
uml-1# sho router-id
router-id: 192.168.50.3
At the linux shell I can ping across the ethernet
subnet.
In ospfd I did a 'sho ip ospf nei':
on comp A:
uml-1-ospf# sho ip ospf nei
Neighbor ID Pri State Dead Time
Address Interface
RXmtL RqstL DBsmL
on comp B:
uml-1-ospf# sho ip ospf nei
Neighbor ID Pri State Dead Time
Address Interface
RXmtL RqstL DBsmL
From the linux shell I can't ping the router-id th
other machine:
[root@laleh root]# ping 192.168.50.3
connect: Network is unreachable
But before starting zebra, ospf and mplsd, when I
ping, there were responses:
[root@laleh root]# ping 192.168.50.1
PING 192.168.50.1 (192.168.50.1) from 192.168.2.231 :

In mplsd, I did a 'sho ldp' and 'sho ldp nei':
comp A:

I don't know how to redirect the output of mplsd to a
file(it's very simple question, sorry)
Why there is no label distributed?!
I really appreciate your help.
Thanking in advance.
