Abstract:
In one example, a management component executes on a network device, a first routing component executing on a first server device physically separate from the network device to provide control plane routing functionality for a virtual node on the network device, and a second routing component executing on a second server device physically separate from the network device to provide control plane routing functionality for the virtual node, wherein the first routing component and the second routing component operate as a redundant master-backup pair for the virtual node. The management component is configured to detect first reachability of the network device with a first routing component and second reachability of the network device with a second routing component, and send a control message to each of the first routing component and the second routing component, the control message specifying reachability information indicating the first reachability and the second reachability.

Claim (Index 19):
The method of  claim 18 , wherein determining, by the first routing component, whether to operate as the master routing component for the virtual node comprises:\n if the first routing component is currently a backup, and both master reachability bits are not set, acquiring mastership to operate as the master routing component, if the first routing component is currently the backup routing component, and at least one master reachability bit is set, continuing to remain as the backup routing component; if the first routing component is currently the backup routing component, and no subsequent control message is received within a configurable time period, continuing to remain as the backup routing component; if the first routing component is currently the master routing component, and at least one master reachability bit is set, continuing to remain as the master routing component; if the first routing component is currently the master routing component, and both master reachability bits are not set, relinquishing mastership to operate as the backup routing component; and if the first routing component is currently the master routing component, and no subsequent control message is received within a configurable time period, relinquishing mastership to operate as the backup routing component.
