VPLS Not working over MPLS

[Darren_Saliva]

Hi, I have some EXOS VM's set up in GNS3 using Virtual box. I used this link to configure MPLS and VPLS https://extremeportal.force.com/ExtrArticleDetail?an=000081349 The only difference is that I have 4 switches instead of 2. I setup 2 more switches to use as the "customer" to see if traffic was being passed over VPLS from one "customer" switch to the other. It is not. I'm not sure what I'm missing. i am including my MPLS/VPLS configurations for each LSR and a screenshot of my setup in GNS3.

As you can see on the screenshot, I am only testing between Incap-Boca and Incap-Chi. those 2 switches are connected to the service VLAN on their respective LSR's.

I am new to MPLS so any help would be much appreciated. Thank you in advanced for any help you provide.

I've typed the enable command on all the MPLS devices but the show vpls command says that the status is still down:

[Henrique]

Can you please send a "show iproute" output?

I believe that you should enable ldp protocol for all MPLS devices even if using RSVP-TE as follows:

enable mpls protocol ldp

[Antonio_Opromol]

Hi Henrique, on both Glasgow and Birmingham, the vpls_service VLAN has 1 port and the status is active:

[Henrique]

Hi Antonio,

LSP sharing + max-gateways commands are not available in VM. The max-gateways setting changes how the HW is configured for multi-path and there is no EXOS VM emulation for that.

Since that's not mandatory (LSP Sharing) I believe you can get this lab working in EXOS VM environment (just remember that no traffic from CE will ingress the tunnel, however you can ping between PEs using the service vlan IP, if configured).

Is there any active (link-up) port in the service vlan "vpls_service"? That might explain the "Down" state for the PW

[Antonio_Opromol]

I add the followinf two screenshots where the error message is a "Route error"....maybe some mistake in the routing configuration...
