hi again ,

i tried this time using 1x G/E, 1000 BASE-SX connected to annother router
and it is working.

but I'm still trying to figure out why back to back link ( crossover cable)
on the same physical router is nnot working,
I added new 4x F/E, 100 BASE-TX PIC and trying to crossconnect the 2 PICs
but noway !!!

set logical-routers PE2 interfaces fe-0/2/0 unit 0 family inet address
10.0.123.1/30
set logical-routers PE3 interfaces fe-0/3/0 unit 0 family inet address
10.0.123.2/30

any idea ????
