Hi all,
I have a VPLS (think MPLS, but at layer 2 only) that connects all our locations together. Over the connection, there is an untagged network and a tagged network.
For some reason the tagged network (VLAN 101) is dropping frames to one specific location (around 20%), but the untagged one isn't. The rest of the locations that connect over the VPLS don't have issues with the VLAN or connection and the ISP claims it's not an issue on their side and they don't see any errors. All cables within my control have been replaced just in case to no avail.
Is there anything I'm missing here? Is there a good procedure for debugging this? The devices on both sides of the connection are Fortigates and are both pinging fine over the untagged network.
Thanks in advance.
