Example for Configuring Association Between EFM and CFM
This section provides an example showing how to configure association between EFM and CFM.
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
, CE1 is dual-homed to PE1 and PE3. The requirements
on the network are as follows:
l
The connectivity of links between CE1 and PE3, between PE3 and PE4, and PE4 and CE2
can be monitored.
l
If the link between CE1 and PE3 goes faulty, CE2 can detect the fault, preventing return
traffic from being forwarded to PE4.
l
When the link between PE3 and PE4 goes faulty, CE1 or CE2 can detect the fault.
l
If the link between CE1 and PE3 goes faulty, a master/backup link switchover can be
implemented.
