Hi Gents,

We have VPNV4 routes getting from peer PE3 router on my two local routers PE1 & PE2. Below is the screenshot. Now VPNV4 routes transferred to PE1 VPN-instance but not in PE2 VPN-instance as both have same import  RT value.


My question is why not transferring to PE2 vpn_instance VPN1_in as transferred to PE1 vpn-instance VPN1_in.....both have same import RT.



The below picture is PE2 10.2.33.0  Route is best & valid.

PE2



The below picture is PE2 10.2.41.0  Route is best & valid.

PE2


The below pictues is PE2 10.2.33.0 & 10.2.41.0 Routes not best & valid in vpn-instance VPN1_in.....but in above picture is best & valid but in vpn-instance VPN1_in not best & valid.

PE2

From your output, on PE2, the VPNv4 route doesn't iterate to a MPLS tunnel, you are kindly advised to check the MPLS tunnel between the PE2 and the route sender.
You can follow the steps Viktor listed.

You only can send routes witch is installed on your FIB. Routes installed on FIB are marked with "*". We need more information about your configurations to inform why this routes are not selected for FIB.

Hi friend hope below can help:


1. Configure the device to import IPv4 direct routes, static routes, or IGP routes from one VPN instance to another VPN instance.

2. Configure the device to import IPv4 BGP routes from one VPN instance to another VPN instance's BGP routing table.

3. Configure the device to import BGP-labeled routes in a VPN instance's labeled address family to a specified VPN instance's BGP routing table.

4. Configure the device to import BGP-labeled routes in a VPN instance's labeled address family to the routing table of a specified VPN instance's BGP-labeled address family.

5. Configure the device to import BGP routes in a VPN instance to the routing table of a specified VPN instance's BGP-labeled address family

Can you share the topology and key configurations? From the screenshots, we cannot know which IP addresses belong to which devices.

Good morning, Guys!

As for VPN environment, you can check your particular route and see why the route is not installed in the VPN instance routing table.
display bgp vpnv4 all routing-table 10.2.33.0 30
What comes to my mind - if you already have your routes in BGP RIB - maybe you have the NEXT-HOP reachability problem, it means you do not have tunnel towards Next-Hop.

Thank you and have a great day!
Viktor

Good day, @LSA!
As you can see from the problem route detail- in the Relay Tunnel Out-Interface: NO TUNNEL IS Available. And also it is Not Valid, Active or Best.
As always, the issue is somewhere on top 
Please, check:
- Do you have IP route towards 172.16.1.11 – make ping 172.16.1.11
- If MPLS LSP is present 172.16.1.11 – tracert lsp
- If MPLS is activated on Interfaces
- If MPLS LDP peers are established
- compare the ping and tracert LSP results with the devices that already wor
