Abstract
Methods and systems for active-standby switchover are disclosed. Embodiments of the present technology may include a method for operating a network with active and standby host nodes that involves transmitting a Border Gateway Protocol (BGP) route advertisement message from the standby host node, the BGP route advertisement message including route information and a community tag that is indicative of a graceful attract community, receiving the BGP route advertisement message at leaf nodes and spine nodes of the network, wherein the leaf nodes and the spine nodes assign higher BGP preference to the route information in the BGP route advertisement message in response to identifying the community tag in the BGP route advertisement message as being indicative of a graceful attract community, and transmitting a BGP route withdraw message from the active host node after the BGP route advertisement message is transmitted from the standby host node.
