Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the following embodiments are only examples for helping to understand the technical solutions, and are not intended to limit the present invention.

[0031] In the present invention, for the two border gateway protocol (Border Gateway Protocol, BGP) neighbors that have established the connection, the BGP neighbor requesting to obtain the routing information is the requesting party, and the BGP neighbor sending the routing information to the requesting party according to the request is the routing provider.

[0032] Such as figure 1 As shown, this embodiment discloses a method for obtaining routing information.

[0033] The requester extends the Border Gateway Protocol (BGP) message, and adds a route refresh filter flag (Refresh Filter Flag, RFF) and a refresh route filter entry (Refresh Route Filter Entry, RRF...

Abstract

The invention relates to a method for requesting obtainment of routing information and corresponding routing equipment. The method comprises the following steps: a requester expands a border gateway protocol (BGP) message and adds a route refresh filter flag (RFF) and a refresh route filter entry (RRF) to the BGP message, wherein the RFF means that a route provider is requested to filter all the routing information in a routing information set Adj-Rib-Out corresponding to the requester according to the RRF to obtain the routing information; and the requester sends the expanded BGP message to the route provider to request obtainment of the routing information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for requesting to obtain routing information and corresponding routing equipment. Background technique [0002] Border Gateway Protocol (Border Gateway Protocol, BGP) is used to control and forward large-scale routing information between autonomous domains (Autonomous System, AS). [0003] A refresh (Refresh) message is a BGP protocol message defined by RFC2918, and the message carries address family information, such as address family identifier (AFI) / subaddress family identifier (SAFI). When issuing a route refresh request, the requester specifies address family information in the Refresh message, and the route provider receiving the Refresh message publishes all routes under the address family information to the requester. The Refresh message is a one-time route refresh request. The route provider determines the route to be sent to the requester according to the add...
