Hi, I wonder can someone explain something to me. I am trying to telnet to a remote management loopback ip address in a VRF from my PC. The host ip address is 172.25.64.13. I can see the packet all the way through to the CE router. The route has been added to the VRF on the router but when i check the bgp vrf table, the next hop is 0.0.0.0 rather than the other end of the WAN link on the PE.
So, the tcp packet never reaches the end-device.
If I remove the host route 172.25.64.13 from the VRF on this router, I can now get to the end device and when I do a traceroute, I can see the traceroute leaving the router and hitting the 1st hop on the PE.
Any idea what the 0.0.0.0 means in the next hop column and where it is picking this up?

This router sits behind a firewall. I am trying to telnet from a device 126.96.36.199 to end destination 172.25.64.13(CE router)
Schematic is :-
Host device 188.8.131.52 - Customer LAN - Firewall - Router - MPLS WAN cloud - CE router 172.25.64.13.
The routes do appear in the show ip ro vrf Astron. For some reason when I do a traceroute from this router, the packet never leaves the router. If I remove the static route 172.25.64.13/32 which is pointing out the wan interface, the traceroute finally leaves the router and heads out over the WAN
One more thing, in relation to the diagram you provided, where does the traceroute stop when you remove the static route? The issue might be that either the remote PE or CE don't have a route back to the source (184.108.40.206 or is this source natted?).
Hope this helps,

When I remove the static route for 172.25.64.13, I can now see an incoming BGP route for 172.25.64.13 with a next hop of 220.127.116.11. This is the PE my CE Router has a BGP neighbor established with. I can now telnet to the CE Router 172.25.64.13 and can ping this address from the HOst device 19.467.240.66.
