我们的网络和客户网络之间有 BGP，到目前为止，每个连接都使用私有 AS 编号（在我们这端，我们为每个连接使用不同的 AS 编号）

我们最近获得了一个公共 AS 编号，用于连接到提供商。现在我们有了这个公共 AS 号，我们应该在我们自己的路由器之间内部使用它（即在设备之间部署新的 BGP 会话等时） - 还是应该继续使用私有 AS 号？

根据我的收集，我们将使用一个 AS 编号（我们的公共 AS 编号）来代表我们的组织（在我们的路由器内部和外部之间）我们可以（这将是公共 AS 编号）。这是正确/最佳实践吗？

我快速浏览了 RFC 1930，其中指出：

 The classic definition of an Autonomous System is a set of routers
 under a single technical administration, using an interior gateway
 protocol and common metrics to route packets within the AS, and
 using an exterior gateway protocol to route packets to other ASes.
 Since this classic definition was developed, it has become common
 for a single AS to use several interior gateway protocols and
 sometimes several sets of metrics within an AS.  The use of the
 term Autonomous System here stresses the fact that, even when
 multiple IGPs and metrics are used, the administration of an AS
 appears to other ASes to have a single coherent interior routing
 plan and presents a consistent picture of what networks are
 reachable through it.

    To rephrase succinctly:

 An AS is a connected group of one or more IP prefixes run by one
 or more network operators which has a SINGLE and CLEARLY DEFINED
 routing policy.
