1. A method for segment routing service processing, applicable to a first segment routing (SR) node, the method comprising:
configuring by the first SR node, a local segment identifier (SID), the local SID being used for indicating an associated SR proxy node and preventing the associated SR proxy node from being assigned with an SID, wherein the first SR node is adjacent to the associated SR proxy node;
notifying by the first SR node, reachable information to a second SR node, the reachable information comprising the local SID;
acquiring by the first SR node, service attribute information of the associated SR proxy node; and
transmitting by the first SR node, a notification message containing the service attribute information to the second SR node;
wherein, the method further comprises:
generating by the first SR node, a forwarding table according to related information of the associated SR proxy node;
receiving by the first SR node, an SR service message orchestrated by the control plane;
transmitting by the first SR node, the SR service message to the associated SR proxy node according to the forwarding table; and
receiving by the first SR node, the SR service message returned by the associated SR proxy node; and
before transmitting by the first SR node, the SR service message to the associated SR proxy node according to the forwarding table or after receiving by the first SR node, the associated SR service message returned by the SR proxy node, the method further comprises:
processing by the first SR node, the SR service message according to the forwarding table.
