The present application provides a method and apparatus for synchronizing information between switches. The method includes: acquiring to-be-synchronized target data; sending BGP routes carrying the target data through BGP sessions established between the switch with one or more designated switches, so that the target data is synchronized between the switch and target switches that need to synchronize with the switch.

Method for synchronizing information between switches, and electronic device

An Egress Tunnel Router (ETR) may establish a neighbor connection with a Map Server (MS). After the ETR establishes the neighbor connection with the MS, or after the ETR detects a status update of the MS from inaccessible to accessible, the ETR may register all Endpoint Identifiers EIDs configured on the ETR with the MS. After the ETR receives a register acknowledgement message with regard to a registered EID from the MS, the ETR may stop registering the registered EID with the MS.

Endpoint identifiers registration

The disclosure relates to a method of routing for an Autonomous System AS in a communication system, in which the AS comprises a plurality of network devices including a first network device and a second network device. The first network device distributes routing information to a forwarding table by calculating a first route from the first network device to the second network device. The first network device receives information of a destination network device of the communication system from the second network device, and forms a second route from the second network device to the destination network device to be stored in the forwarding table using the received information of the destination network device. When the first route fails, the first network device calculates a third route from the first network device to the second network device and updates the routing information in the forwarding table according to the third route.

The present disclosure describes reducing flooding of link state information of a link state protocol in a network with multiple routers. A filtering strategy is pre-configured on a router interface for filtering link state information generated by a first router. The filtering strategy is to enable link state database (LSDB) isolation between a second router associated with the router interface and the first router. Link state information generated by the first router is received or sent according to the pre-configured filtering strategy via the router interface.

Reducing flooding of link state information

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.
