Abstract: Provided in the embodiments of the present disclosure are a method and apparatus for receiving border gateway protocol routing, and a method and apparatus for sending border gateway protocol routing, and a storage medium. The receiving method includes: Virtual Private Network (VPN) service routing is received by a first Provider Edge (PE) device in a first domain from a second PE device in a second domain, where the VPN service routing includes an address of the second PE device; an Outbound Route Filtering (ORF) entry strategy is generated by the first PE device according to the VPN service routing, and the ORF entry strategy is sent to a border device, where the ORF entry strategy includes the address of the second PE device; and Border Gateway Protocol (BGP) routing matching the ORF entry strategy and sent by the border device is received by the first PE device.

Abstract: A BGP route sending method includes: receiving, by a second node, a first BGP route advertised by a third node, wherein the first BGP route carries a first attribute and a second attribute; performing, by the second node, first processing on the second attribute to obtain a second BGP route, wherein the second node is unable to recognize the first attribute, but has a capability of recognizing the second attribute; and in response to the second node being unable to recognize the first attribute, adding, by the second node, first indication information to the second BGP route while retaining the first attribute in the second BGP route, and sending, by the second node, the second BGP route to the first node, wherein the first indication information is indication information used for indicating whether the first processing affects the first attribute.

Abstract: Provided in the embodiments of the present disclosure are a method and apparatus for receiving border gateway protocol routing, and a method and apparatus for sending border gateway protocol routing, and a storage medium. The receiving method includes: Virtual Private Network (VPN) service routing is received by a first Provider Edge (PE) device in a first domain from a second PE device in a second domain, where the VPN service routing includes an address of the second PE device; an Outbound Route Filtering (ORF) entry strategy is generated by the first PE device according to the VPN service routing, and the ORF entry strategy is sent to a border device, where the ORF entry strategy includes the address of the second PE device; and Border Gateway Protocol (BGP) routing matching the ORF entry strategy and sent by the border device is received by the first PE device.

Abstract: Provided are a protocol processing method and apparatus, and a storage medium. The method includes: in a Routing In Fat Tree (RIFT), supporting an RIFT community structure to carry a Point of Delivery (PoD) field, and controlling, by a configured community structure policy, import or export of an RIFT route indicated in the PoD field.
