Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0049] The embodiment of the present application provides an SRMS policy infiltration method, which can be applied to an ABR in an OSPF network (for ease of distinction, it may be called the first ABR). An OSPF network can include one backbone area and multiple non-backbone areas. There can be multiple common routing devices in the backbone area and non-backbone areas, and the interfaces of the common routing devices belong to the same area. An ABR with SR capability can be set bet...

Abstract

Embodiments of the present application provide a method and device for infiltrating SRMS policies of a label mapping server, which relate to the field of communication technologies. The method is applied to the first area border routing device ABR supporting the leaking function in the open shortest path first OSPF network, and the first ABR is connected to at least one non-backbone area, and the method includes: when receiving the When using the SRMS policy, determine the target non-backbone area corresponding to the SRMS policy, if in the pre-stored correspondence between the non-backbone area and the device identifier of the ABR, the maximum preset number of devices corresponding to the target non-backbone area If the ID includes the device ID of the first ABR, the SRMS policy is subjected to penetration processing between the backbone area and the target non-backbone area. The application can avoid the waste of network resources.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a method and device for infiltrating SRMS policies of a label mapping server. Background technique [0002] Currently, a network applying an Open Shortest Path First (English: Open Shortest Path First, OSPF for short) routing protocol usually includes a backbone area and multiple non-backbone areas. There can be multiple common routing devices in the backbone area and non-backbone areas, and the interfaces of the common routing devices belong to the same area. There is an area border router (English: area border router, ABR for short) capable of segment routing (English: Segment route, SR for short) between the backbone area and the non-backbone area. Some interfaces of the ABR belong to the backbone area, Some interfaces belong to non-backbone areas. Through the ABR, the label mapping server (English; segmentrouting mapping service, SRMS for short) policy pene...
