I would like to build a dedicated VPN to manage all CEs on my network. All CEs should be connected only to my NOC CE (where is my all NMS), and conversatins between CEs cannot occour.
I my lab, I test this environment, but allways all CEs connected on same PE can connect.
I need to know if anyone experienced this situation and how to fix it.
Thank's

I guess you are looking at a hub & spoke MPLS-VPN solution where the NOC-hub should communicate with all CEs, but the CEs (spokes) should not communicate with each other.
You may have to manipulate the route targets to achieve this.

Hi there, The title and the description are not in sync. I am confused as what you are looking for. Route-maps make route manipulation really flexible. Forward your topo and configs if you still want a solution.

Hello Jose,
In your case, the best topology would be a hub and spoke MPLS VPN, where the spokes cannot see each other. For this route-targets should be manipulated.
Consider central site X, remote CE sites A and B.
On the PE For the 2 sites, A and B, you would be creating two VRFs for each site. say VPN_A and VPN_B.
ip vrf VPN_A
rd 10:1
route-target export 100:1
route-target import 200:1
ip vrf VPN_B
rd 20:1
route-target export 300:1
route-target import 200:1
On the PE For the NOC CE,
ip vrf VPN_NOC
rd 30:1
route-target export 200:1
route-target import 100:1
route-target import 300:1
This should isolate the VPN connection from each CE to NOC CE. Individual CEs wont see each other in this case.

Hi, the best solution would be to setup managed router service (a central service like VPN topology) The idea is: have a separate NMS vrf and import only the loopback IPs from the managed CEs. Mark those routes through a route-map with an additional RT and import it in vrf NMS. mark your NMS networks with another RT and export the routes.
In case you need an example config, let me know.
kind regards
