The present disclosure describes traffic forwarding in a network where a virtual local area network (VLAN) exists in multiple network sites that are geographically dispersed and connected via virtual links. A first edge device (ED) at a first site receives, from a second ED at a second site, information identifying a VLAN of the second ED through a virtual link. The VLAN identified in the information is an active VLAN of the second ED. An association between (i) the VLAN of the second ED and (ii) the virtual link through which the information is received from the second ED is recorded. When forwarding traffic to the VLAN of the second ED, it is determined the virtual link associated with the VLAN of the second ED is determined based on the recorded association and the traffic is forwarded via the determined virtual link.

Traffic forwarding

According to an example, a change of a system ID for a node in a link state protocol network is notified to other nodes in the network. A message may be sent to notify the other nodes of the system ID change.
