Hello,
I am trying to test some features with an MX5-T router with
logical-systems but my results are below expectations and I don't
understand what's wrong.
The topology and the config are very simple: R1 --- R2 ---R3 :
mx5t# run show version
Hostname: mx5t
Model: mx5-t
JUNOS Base OS boot [11.4R2.14]

mx5t# show R3
interfaces {

peer-unit 23;
family inet {

}
family iso;
family mpls;
}
}
lo0 {
unit 1003 {
family inet {

}
family iso {

}
}
}
}
protocols {
rsvp {

}
mpls {
interface all;
}
isis {
interface all;
}
}
While a ping from R1 loopback to R3 loopback is successful , a traceroute
from R1 to R3 doesn't show the transit router R2 (I tried with and without
mpls), and a lsp from R1 to R3 is failing to come up.
