Flag bit.
If so, executing S307；If it is not, can then ignore the handoff notification message.
For example, if the switching mark position of itself storage is 0, and the switching mark position carried in handoff notification message is 1, then
It can determine that active-standby switch has had occurred in other backup groups in linkage switch groups.
S307, firewall 1 are by service switching to firewall 2.
Wherein, firewall 2 can be switched to main equipment by IRF process by service switching to firewall 2 by firewall 1.
The switching mark position that itself is stored is updated to the switching mark carried in handoff notification message by S308, firewall 1
Position.
Disappear it should be noted that the switching mark position itself stored is updated to switching notice by IRF process by firewall 1
The switching mark position carried in breath, since the backup group being made up of IRF agreement is considered as a combination plant, in backup group
Each equipment can regard component units of the combination plant as, which can run an IRF process, it is possible to understand that
Be each equipment in backup group use the same IRF process, so IRF process can make firewall 2 store switching mark position with
The switching mark position that firewall 1 stores is consistent, it is understood that shares the same switching mark position for firewall 1 and firewall 2.
The embodiment of the present application increases new notification packet (i.e. handoff notification message), as caused by non-interface fault
After active-standby switch occurs, using the method for the equipment linkage switching that embodiments herein provides, interchanger 1 can switch to linkage
Other equipment in group send handoff notification message, after the firewall 1 as main equipment receives the handoff notification message, if
Determine itself storage linkage switching group number with itself belonging to linkage switching group number it is identical, and itself store switching mark position
Less than the switching mark position that handoff notification message carries, then can determine in other backup groups in the linkage switch groups belonging to itself
Active-standby switch has occurred, it, can be by service switching extremely in the case where firewall 1 knows that active-standby switch has occurred in other backup groups
Firewall 2, and then the physical interface of firewall 2 will become activated state, two backup groups in the switch groups that link can still communicate, and keep away
Exempt from the case where network interruption occur.
It should be noted that active-standby switch occurs between the interchanger in Fig. 1 in Fig. 3, trigger between firewall into
For row active-standby switch.Conversely, actively switching if first having occurred between firewall, the side of linkage switching is carried out between interchanger
Method is similar with the above method, i.e., after firewall 1 is by service switching to firewall 2, switching mark that firewall 1 stores itself
Position plus 1, and the other equipment into linkage switch groups send handoff notification message, after interchanger 1 receives handoff notification message,
It can be according to handoff notification message by service switching to interchanger 2.
As it can be seen that may be implemented in by the above method using under VRRP agreement and the scene of IRF combination of protocols networking, if wherein
