[j-nsp] LDP/MPLS is mandatory in the route-reflector bgp vpnv4 uplink?

[Ricardo Tavares]

Hi guys,

I did some tests using JunOS 9.4 acting as BGP reflector for vpnv4
address-family and found that when I disable LDP in the uplink to the MPLS
core the routes sent by this reflector are discarded by the PEs (Cisco or
Juniper) but the routes advertised by a Cisco router acting as vpnv4
reflector works fine without LDP.

 Is this a normal behavior? If yes someone can explain the process? If yes
maybe there is a knob to control this?

Best Regards,
