Sure, you can create a second dummy interface with the same address on the default VRF and it should work fine. On Fri, Jan 18, 2019 at 2:32 PM Alessio Leonarduzzi <alessio.leonarduzzi@gmail.com> wrote:
Hi Renato,
thank you for the tip. That loopback is also announced by OSPF so I can not move to default VRF. Is it possible to set a second dummy interface in default VRF only for LDP?
regards
Alessio

Hi Alessio,
It seems your dummy0 interface (which has the 1.1.1.1/32 address) is assigned to the VRF-PUBLIC VRF, and ldpd works on the default VRF only. Moving dummy0 to the default VRF should fix the problem.
Best Regards, Renato.

Hi all,
If I set loopback interface IP as discovery transport-address in MPLS configuration the DEBUG output is: [CUT] 2019/01/17 12:05:19 LDP: nbr_establish_connection: error while binding socket to 1.1.1.1: Cannot assign requested address 2019/01/17 12:05:23 LDP: nbr_establish_connection: error while binding socket to 1.1.1.1: Cannot assign requested address 2019/01/17 12:05:27 LDP: nbr_establish_connection: error while binding socket to 1.1.1.1: Cannot assign requested address 2019/01/17 12:05:32 LDP: nbr_establish_connection: error while binding socket to 1.1.1.1: Cannot assign requested address 2019/01/17 12:05:36 LDP: nbr_establish_connection: error while binding socket to 1.1.1.1: Cannot assign requested address 2019/01/17 12:05:40 LDP: nbr_establish_connection: error while binding socket to 1.1.1.1: Cannot assign requested address [/CUT]
but if I use the physical interface all works good.
This is the configuration:
vrf VRF-PUBLIC ! interface dummy0 vrf VRF-PUBLIC description Loopback0 ip address 1.1.1.1/32 ! interface enp2s0f0 vrf VRF-PUBLIC description P2P01 ip address 2.2.2.2/30 ip ospf network point-to-point ! interface enp2s0f2 vrf VRF-PUBLIC description P2P02 ip address 3.3.3.3/30 ip ospf network point-to-point ! mpls ldp router-id 1.1.1.1 dual-stack cisco-interop ! address-family ipv4 discovery transport-address 1.1.1.1 label local advertise explicit-null ! interface enp2s0f0 interface enp2s0f1 ! exit-address-family ! !
The FRR version is 6.0.2 and I need to use MPLS on two interfaces (enp2s0f0 and enp2s0f1).
thank you for your help
