Example for Configuring Association Between EFM and BFD
This section provides an example showing how to configure association between EFM and BFD.
Networking Requirements
As networks develop quickly, more and more IP networks are used to bear multiple services
such as voice and video services. These services pose high requirements on network reliability
and rapid fault detection.
Link detection protocols are usually deployed on a network to detect link connectivity and faults.
As network environments become increasingly complex, it is impossible to detect all link faults
using a single detection technique. Network environments and user requirements, therefore, need
to be properly analyzed, and various detection techniques are required to implement rapid link
fault detection.
On the network shown in
