I saw it before, but it's strage since I do not guess that lldp pkt can be filtered (I've BGP peering between two sites).

Sometimes line flap and BGP goes down, but when it's up the line (and BGP) I expect to have lldp neighbor up.

What does "show lldp statistics" show for the interfaces connected to each other?

What version Junos? I ran into some LLDP bugs on early 11.4 versions.

I’ve a couple of EX in VC configuration

mode (same Junos) connected with two links in LAG mode and LLDP switched-on on the

aggregate interface.



The problem is that on one VC I see

lldp neighborship with the other, on the other nothing…



Any idea ?
