摘　　要：网络可靠性的一项重要标准在于这个网络是否能够快速检测并复原。由于大部分网络技术自带的检错机制效率很低,无法实现快速检测,而BFD作为一种毫秒级的、能给大量协议提供快速检测服务的机制,因此被广泛应用。本文阐述了BFD的工作原理及结合VRRP网络中可能出现的故障场景,提出了BFD与VRRP联动设计的快速复原解决方案。该方案在ENSP进行模拟演示,最终验证方案的快速有效性。An important criterion for network reliability is whether the network can be quickly detected and restored.Due to the low efficiency of most network technologies'built-in error detection mechanisms,fast detection cannot be achieved.As a millisecond level mechanism that can provide fast detection services for a large number of protocols,BFD is widely used.This article explains the working principle of BFD and proposes a fast recovery solution for the linkage design of BFD and VRRP,combined with possible fault scenarios in VRRP networks.The scheme was simulated and demonstrated in ENSP,ultimately verifying its fast and effective performance.
