Boa noite!!
Subi dois routers XRv com configuração MPLS com LDP. Contudo nao consigo vizinhança MPLS, LDP e a tabela de roteamento não tem o protocolo MPLS.

Olá, você precisa habilitar o OSPF para que ambos os roteadores reconheçam suas loopbacks e, em seguida, ajustar as configurações de MPLS.
Exemplo AGG01:
#### OSFP CONFIG MPLS####
router ospf 1
router-id 1.1.1.1
mpls ldp sync
mpls ldp auto-config
area 0.0.0.0
network point-to-point
interface GigabitEthernet0/0/0/1
interface Loopback0
##### MPLS ####
mpls ldp
router-id 1.1.1.1
address-family ipv4
!
label
local
allocate for host-routes
interface GigabitEthernet0/0/0/1
