Method and apparatus for accessing a virtual IP address across clusters, electronic device, and storage medium

Abstract

A method for accessing a virtual IP address across clusters is provided. The method is applied to a gateway node of a first cluster, where the first cluster is connected to a second cluster through a router, and the method includes: matching a received packet with a flow table, where the packet carries a virtual IP address and a MAC address corresponding to the virtual IP address; and in response to the packet being successfully matched with a first flow entry in the flow table, determining that the virtual IP address drifts into a virtual machine in the first cluster, and adding static routing corresponding to the virtual IP address to a router of the second cluster according to the virtual IP address and the MAC address corresponding to the virtual IP address to enable the second cluster to access the virtual IP address in the first cluster.
