Abstract: Various implementations disclosed herein include apparatuses, systems, and methods for providing virtual/virtualized network functions. In some implementations, a method includes determining that a first virtual router is configured to operate as a backup router for a second virtual router. The first virtual router and the second virtual router may reside within a public cloud. The method also includes determining, by the first virtual router, whether the second virtual router is able to route packets. The method further includes updating, by the first virtual router, a routing table to indicate that the first virtual router should be used to route packets when the second virtual router is unable to route packets.

Abstract translation: 本文公开的各种实现方式包括用于提供虚拟/虚拟化网络功能的装置，系统和方法。 在一些实现中，一种方法包括确定第一虚拟路由器被配置为作为第二虚拟路由器的备份路由器进行操作。 第一虚拟路由器和第二虚拟路由器可以驻留在公共云中。 该方法还包括由第一虚拟路由器确定第二虚拟路由器是否能够路由分组。 该方法还包括由第一虚拟路由器更新路由表以指示当第二虚拟路由器不能路由分组时，应当使用第一虚拟路由器来路由分组。
