Hi,
Well, more details would certainly be useful ;-)
A few thoughts.. While mpls ldp sync will make ospf advertise the link out
with maximum cost it shouldn't prevent ospf from turning up. You might want
to look at the following:
C: show mpls ldp igp sync
C: show ip ospf interface your_interface
C: show ip ospf mpls ldp interface
J: show ospf interface detail your_interface
J: show interfaces your_interface | match mtu
On the J you want to enable traceoptions under protocols ospf, probably
something like this:
traceoptions {
file ospf-debug;
flags ldp-synchronization;
flags normal;
flags general;
flags event;
flags hello;
}
Check out the file using show log ospf-debug or if you want to tail it in
realtime with monitor start ospf-debug
On the C you want to, at least, debug ip ospf {adjacency,events} and debug
mpls ldp igp sync . Assuming this is really production be careful with debug
on IOS.
Out of curiosity, what IOS and JUNOS are you on? I'm kind of assuming you're
running 12.0S and not XR on the PRP.
