Establishing neighbor connection

摘要

According to an example, virtual systems are established in a same Intermediate System to Intermediate System (IS-IS) process as a local IS-IS system. Each local IS-IS system and virtual system can enable a maximum of M IS-IS interfaces. A system is selected for each IS-IS interface from the local IS-IS system and the virtual systems. A virtual neighbor connection is established between the local IS-IS system and each of the virtual systems, and a route cost of the neighbor connection is 0. For an IS-IS interface connected to a remote device, a packet is sent for establishing a neighbor connection with the remote device, the packet carrying a system ID of the IS-IS interface.

1. A method for establishing a neighbor connection, comprising:
establishing, by a local device, N virtual systems in a same Intermediate System to Intermediate System (IS-IS) process as a local IS-IS system, wherein
N is an integer being greater than or equal to 1,the local IS-IS system and the N virtual systems are identified using different system IDs, and determining, for each IS-IS interface of the local device, a system from the local IS-IS system and the virtual systems; enabling, by the local device, each IS-IS interface; establishing, by the local device, virtual neighbor connections between the local IS-IS system and each of the virtual systems, each virtual neighbor connection having a route cost of 0; and sending, by the local device, a packet to establish a neighbor connection with a remote device via an IS-IS interface connected to the remote device, the packet carrying a system ID of the IS-IS interface.
