MPLS VPRN (L3 VPN) Interop — Nokia 7750 and Cisco 7200 on GNS3
Introduction
In my previous article, I showed how to setup and test layer 2 MPLS ePipe Pseudo Wire network service between Nokia 7750 and Cisco 7200 routers on a Windows 10 PC running GNS3. RSVP-TE and TLDP are used as the signalling protocols to establish the MPLS Transport and Service Tunnels respectively for the MPLS ePipe service. Since ePipe is a layer 2 network service, the virtual PCs connected at the two ends of the MPLS ePipe on GNS3 need to be on the same IP subnet in order for the PCs to ping to each other.
In this article, I will show how to setup and test layer 3 MPLS VPRN network service between Nokia 7750 and Cisco 7200 again on GNS3. This time, LDP and MP-BGP are used as the signalling protocols for establishing the MPLS Transport and Service Tunnels respectively for the layer 3 network service.
The following shows the lab setup on GNS3 on the same Windows 10 PC used in the previous ePipe interop article. Note that R7 and R8 are Nokia 7750 routers and R9 is a Cisco 7200 router.
A VPRN 200 is setup on the three routers. Unlike ePipe which is a layer 2 network service, VPRN…
