Abstract:
Described are mechanisms for verifying configuration information in 2547 BGP VPNs. An originating PE generates a first knowledge digest encoding first configuration information associated with a current set of information advertised for a VRF. The originating PE also generates a second knowledge digest encoding second configuration information associated with cumulative information advertised for the VRF. The originating PE is capable of receiving a message from a user PE, the message including a third knowledge digest encoding third configuration information related to the user VRF. The originating PE is capable of comparing the first knowledge digest to the third knowledge digest and producing a first indication if the third configuration information encoded in the third knowledge digest is not a subset of the first configuration information encoded in the first knowledge digest.
