VPLS Not working over MPLS

VPLS Not working over MPLS

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 see that you have configured the same "to-P1" vlan ipaddress between PE1 and PE2 and also between PE3 and PE4. Can you fix that and re-test?

Also, between P and PE's I would create a /30 vlan.

I'll create a similar virtual lab and provide you an update soon

Hi Antonio,

Could you please confirm if "vpls_service" vlan port 1 is UP (Link-up) for all 4 PE's?

To be complete, I've also made a simple test with only two vXOS configured both as follow to see if the problem may due to my vswitches (only ESRP), but it works in this case: create vlan sales configure vlan sales add ports 1-3 configure vlan sales ipaddress 10.1.2.3/24 enable ipforwarding create esrp esrp1 configure esrp esrp1 domain-id 4096 configure esrp esrp1 add master sales enable esrp esrp1 configure ospf routerid 5.5.5.5 configure ospf add vlan sales area 0.0.0.0 passive enable ospf The master-slave states are correctly acquired from the two routers:

Hi Antonio,

Can you please share the diagram and configuration for both PE's?

I believe it should work in the VM since ESRP will keep VPLS status UP/Ready based on it's priority/role. However, I'm not 100% sure since I just worked in this scenario using physical devices.

Hi, I'm trying to create in my virtual environment the scenario descripted in the GTAc solution: https://extremeportal.force.com/ExtrArticleDetail?an=000080251
I've problem with the ERSP domain defined in this case as: create esrp type vpls-redundancy Both PE devices remain in slave state and are not able to know the Master MAC address. If I buils a simple ESRP lab of type standard it works. Is this problems due to the same limitation descripted above regarding the fact that on the vXOS there is no the emulation of the VPLS dataplane? Thanks
