Hello everyone,

BRAS access through a PW and a VXLAN tunnel. shown in, configure a VPLS network and a VXLAN network intersect at Device 2 and Device 4 for BRAS access.

I have completed the configuration, but there is still a problem I do not understand, the question I want to ask is how does the router determine whether a user goes online through a VSI?

Best regards!

Hello@ster,
Becuase VRRP is associated with PWs on the Device 2 and Device 4 interfaces connecting to the BRASs so that the PW interface of the backup device does not receive or forward VXLAN traffic. Therefor user access packets are broadcast to both Device 2 and Device 4 in the VSI. Because PW packets are blocked on the backup device, only the master device forwards the user access packets.
Glad to help you! Any further questions, let us know.
