Management VRRP backup group and service VRRP backup group
Two ways to implement VRRP backup group management
Configure and manage backup groups
When multiple VRRP backup groups are configured on a device, to reduce the exchange of a large number of VRRP protocol packets between devices, one of the VRRP backup groups can be configured as a management VRRP backup group (mVRRP), and the other VRRP backup groups can be Binding the management VRRP backup group
At this time, only the management VRRP backup group will send VRRP protocol packets, and the rest of the VRRP backup groups will not send protocol packets, and the active/standby status of these VRRP backup groups is consistent with that of the management VRRP backup group.
Management VRRP backup group and service VRRP backup group
Configure the normal backup group as the management backup group, this common backup group is called the management backup group
After the common backup group is bound to the management backup group, this common backup group becomes the business VRRP backup group
Note: The service backup group does not send VRRP packets, and its status is determined by the state of the interface where it is located and the state of the bound VRRP management backup group
Two ways to implement VRRP backup group management
Management VRRP and service VRRP are deployed on the same side
At this time, the management VRRP backup group can be used as a gateway, and a virtual IP address needs to be configured.
Management VRRP is responsible for negotiating the active and standby status between devices, and can also undertake business traffic
The business VRRP backup group can only undertake business traffic
Management VRRP is deployed between switches directly connected
At this time, the management VRRP backup group does not need to be used as a service gateway, and the virtual IP address does not need to be configured.
The management VRRP backup group is only responsible for negotiating the active/standby state of the device, not responsible for business traffic
The business VRRP backup group only undertakes business traffic
