Ricardo, I think that's expected simply because VPN-IPv4 Routes resolve in inet.3 (being MPLS based)
To support L3 VPNs, the Juniper Networks PE router uses several routing tables. Inet.0 : The first routing table, inet.0 contains routes learned by the provider's IGP and by BGP. These routes include all destinations within the service provider's own network, including the PE and P routers etc. Inet.3 : The second routing table, inet.3, contains all the routes that are reachable via MPLS LSPs that are learned from either RSVP or LDP. This table provides the connectivity for traffic sent between the PE routers by the CE routers. Bgp.l3vpn.0 : The PE also maintains a routing table referred to as bgp.l3vpn.0. This table stores Layer 3 VPN routes learned from other PE routers. Routes learned from other PE routers are entered into this table when they are received. "The PE router resolves the next hop for these routes by executing a route lookup in the inet.3 table". This enables the PE router to determine the path to the PE advertising the Layer 3 VPN route. So unless you have a route/next-hop in inet.3 (LDP/RSVP), these routes will not be installed & will remain hidden/discarded. Though not sure on cisco's interop part of your query. Hope it helps!

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?
