thanks Nilesh and Cristian ,
I checked the autoneg and it seems ok ( show interface extensive) :
 Autonegotiation information:
    Negotiation status: Complete
    Link partner:
        Link mode: Full-duplex, Flow control: None, Remote fault: OK

I lunch 2 pings :
ping 10.0.24.1 count 1000
ping logical-router PE2 10.0.123.2 count 1000

and I have been collecting info from FEB but nothing happen always same
result before and during and after the pings :

admin at M10> start shell pfe network feb
SBR platform (266Mhz PPC 603e processor, 64MB memory, 512KB flash)

SBR(M10 vty)# bringup bchip 0 read 0x3002
B0 0x00003002: 0x00000000

SBR(M10 vty)#

any idea Nilesh?

Cristian :
information in log chassid seems correct and also there no reject on the
"show route ..." command :
log chassid

show route logical-router PE2

inet.0: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

10.0.123.0/30      *[Direct/0] 12:12:45
                    > via fe-0/3/0.123
10.0.123.1/32      *[Local/0] 12:12:48
                      Local via fe-0/3/0.123
show route logical-router PE3

inet.0: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

10.0.123.0/30      *[Direct/0] 10:47:51
                    > via fe-0/3/1.123

                      Local via fe-0/3/1.123


here is the configuration again :

fe-0/3/0 and fe-0/3/1 back to back connection ( crossover cable )
fe-0/3/2 =>> connected to annother router

set logical-routers PE2 interfaces fe-0/3/0 unit 123 vlan-id 123
set logical-routers PE2 interfaces fe-0/3/0 unit 123 family inet address
10.0.123.1/30
set logical-routers PE3 interfaces fe-0/3/1 unit 123 vlan-id 123
set logical-routers PE3 interfaces fe-0/3/1 unit 123 family inet address
10.0.123.2/30
set chassis aggregated-devices ethernet device-count 1

set interfaces fe-0/3/0 vlan-tagging
set interfaces fe-0/3/1 vlan-tagging
set interfaces fe-0/3/2 unit 0 family inet address 10.0.24.2/30

set interfaces fxp0 unit 0 family inet address 172.31.16.35/25
set interfaces fxp1 disable

any idea

thanks guys
