Hi Renato, in attachment the pcap capture. For this capture I have disabled all traffic-eng on FRR and removed from interface on Cisco. regards Alessio Il giorno mar 22 gen 2019 alle ore 15:37 Renato Westphal < renato@opensourcerouting.org> ha scritto:
Hi Alessio,
Interesting problem. Could you provide a pcap (showing TCP port 646 only) so that I can analyze which LDP speaker is behaving badly?
Your config looks fine to me. Using "mpls traffic-eng tunnels" or not on the Cisco side shouldn't matter since this is one of the commands used to enable RSVP-TE, which is a different protocol.
Regards, Renato.

The OSPF is up and Loopback are in both routing tables. I try with/with-out "mpls traffic-eng tunnels" with same result. Timers/MTU are corrects.
The result is that the devices don't share the labels becouse neighbors are down
This is a bug? or wrong configuration?
