Title: EDGE NODE CLUSTER NETWORK REDUNDANCY AND FAST CONVERGENCE USING AN UNDERLAY ANYCAST VTEP IP
Abstract:
Some embodiments provide a method for providing redundancy and fast convergence for modules operating in a network. The method configures modules to use a same anycast inner IP address, anycast MAC address, and to associate with a same anycast VTEP IP address. In some embodiments, the modules are operating in an active-active mode and all nodes running modules advertise the anycast VTEP IP addresses with equal local preference. In some embodiments, modules are operating in active- standby mode and the node running the active module advertises the anycast VTEP IP address with higher local preference.
