Design and simulation of experiment for application of BFD in VRRP
VRRP is a fault-tolerant protocol widely used in various scenarios,which can effectively improve the reliability of gateway routing devices.However,as VRRP requires a certain amount of time to transition from Backup to Master,using VRRP alone will result in traffic loss.For this reason,this paper applies BFD in VRRP,and when BFD detects the link failure between Master and Backup,it will immediately notify VRRP to transition from Backup to Master.By analyzing principles of VRRP and BFD,this paper designed a simulation experiment for the application of BFD in VRRP based on eNSP,and provides detailed experimental steps.The simulation experiment results show that compared to only using VRRP,applying BFD in VRRP can provide rapid transition from Backup to Master,which greatly reduces traffic loss caused by transitioning and further improves the network reliability.
