Abstract:
Techniques are presented for distributing host route information of virtual machines to routing bridges (RBridges). A first RBridge receives a routing message that is associated with a virtual machine and is sent by a second RBridge. The routing message comprises of mobility attribute information associated with a mobility characteristic of the virtual machine obtained from an egress RBridge that distributes the routing message. The first RBridge adds a forwarding table attribute to the routing message that indicates whether or not the first RBridge has host route information associated with the virtual machine in a forwarding table of the first RBridge. The first RBridge also distributes the routing message including the mobility attribute information and the forwarding table attribute, to one or more RBridges in the network.
