Description

Method and device for checking VRRP configuration

Technical field

This application relates to, but is not limited to, virtual routing techniques in the field of communications.

Background technique

Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. The VRRP protocol consists of two network elements, such as routers, in the local area network. The one network element acts as the primary network element and the other network element acts as the standby network element. When the primary NE is normal, each device in the local area network, such as the host, performs communication through the primary NE and the external device. When the primary NE is abnormal, the VRRP protocol supports each device in the local area network through the standby network element and the external device. Communication.

When the VRRP protocol is used, a VRRP link is required between the two NEs in the virtual router. The VRRP link uses the physical interfaces of the two NEs as their two endpoints. Therefore, the VRRP link is represented by two physical interfaces. When using VRRP, you need to configure one NE to form a virtual router with two or two other NEs. In this scenario, two or more different VRRP objects are usually configured on the same NE. For example, it is assumed that the network element 1 and the network element 2 and the network element 3 respectively form a virtual router. In this case, VRRP object 1 and VRRP object 2 are configured on the network element 1, and VRRP object 3 is configured on the network element 2, and the network is configured. VRRP object 4 is configured on element 3, wherein a VRRP link is established between VRRP object 1 and VRRP object 3, and another VRRP link is established between VRRP object 2 and VRRP object 4. For convenience of description, VRRP object 1 and VRRP object 3 are sometimes referred to as two VRRP objects belonging to the same VRRP link.

A VRRP object belonging to a different VRRP link on a network element device has different identifiers, and two VRRP objects belonging to the same VRRP link have the same identifier. From the above examples, VRRP objects 1 and 2 have different identifiers, while VRRP object 1 and VRRP object 3 have the same identifier, and VRRP object 2 and VRRP object 4 have the same identifier.

Generally, a VRRP object is described by one or more VRRP parameters, and VRRP parameters. The parameters include the identifier of the network element where the VRRP object resides, the VRRP object identifier, the priority, the outbound interface, and the signaling interface. In the art, a VRRP link can be used to represent two VRRP objects belonging to the link, but the VRRP link can only visually represent the two physical interfaces used by the VRRP object belonging to the link, and does not visually represent the VRRP object. Therefore, for the convenience of description, the VRRP master-slave relationship is used to represent the two VRRP objects of the VRRP link and their corresponding relationships. The priority of the primary VRRP object is greater than the priority of the standby VRRP object. It is not difficult to understand that the VRRP master/slave relationship is used to represent the association and active/standby relationship between two VRRP objects.

When the maintenance personnel manually check the VRRP configuration, the VRRP parameters of the primary VRRP object and the standby VRRP object are displayed in the VRRP configuration. The VRRP parameters are obtained through the network management system. aspect:

Whether the ID of the primary VRRP object is the same as the identifier of the standby VRRP object.

Whether the preemption time of the primary VRRP object is equal to the preset preemption time standard value;

Whether the primary and backup VRRP objects are enabled with the ARP (Address Resolution Protocol) learning and free ARP learning.

Whether the primary and backup VRRP objects are enabled for Layer 2 switching.

Whether the primary and backup VRRP objects exchange heartbeat information through the aggregation interface.

Whether the outbound interfaces of the active and standby VRRP objects are all off the three-packet suppression; and,

Whether the heartbeat interface and the outgoing interface of the active and standby VRRP objects are on the same physical circuit board.
