Abstract: In one embodiment, an edge router receives an update message from a neighboring EBGP edge router, creates a modified origin validation state extended community, prepares a modified update message by attaching the modified origin validation state extended community to the update message, and sends the modified update message to a route reflector. The route reflector receives the modified update message, performs a prefix origin validation and a path validation based on the information contained in the modified update message, prepares a validation message based on the prefix origin validation and path validation, and sends the validation message to the edge router and to all other neighboring IBGP edge routers. The edge routers receive the validation message from the route reflector, parse the validation message, and inherit a validation state parsed from the validation message.

Abstract translation: 在一个实施例中，边缘路由器接收来自相邻EBGP边缘路由器的更新消息，创建修改的原始验证状态扩展团体，通过将修改的原始验证状态扩展团体附加到更新消息来准备修改的更新消息，并且发送修改的 更新消息到路由反射器。 路由反射器接收修改的更新消息，基于修改的更新消息中包含的信息执行前缀原点验证和路径验证，基于前缀原点验证和路径验证准备验证消息，并将验证消息发送到 边缘路由器和所有其他相邻的IBGP边缘路由器。 边缘路由器从路由反射器接收验证消息，解析验证消息，并继承验证消息中解析的验证状态。
