Hi @nozomiislove ,

 

You need to change the PEs (R3 and R8) loopback interface addresses to 255.255.255.255 (/32). This is a requirement for MPLS VPN.

Hi @nozomiislove ,

 

I just noticed that you are using BGP between R5 and R6, which means you don't have an end to end LSP between R3 and R8, as BGP is not advertising labels by default. You would need to use BGP label unicast to complete your design. For this, you need to add the following commands on R5 and R6:

 

R5:

router bgp 2

neighbor 10.0.0.2 send-label

 

R6:

router bgp 3

neighbor 10.0.0.1 send-label
