Abstract:
Techniques are presented herein for distributing address information of host devices in a network. At a first router device, a packet is received from a first host device that is destined for a second host device. The first host device is dually-connected to the first router and a second router device. The second router device is part of a virtual port channel pair with the first router device. A message is sent to the second router device, the message indicating that the first host device is connected to the second router device. The packet is encapsulated with an overlay header and is sent to a third router device that is connected to the second host device. The encapsulated packet contains a Layer 2 address associated with the first host device and a Layer 3 address associated with the first host device.
