CFD Configuration Example

Network requirements
As shown in Figure
The network comprises five devices and is divided into two MDs: MD_A (level 5) and MD_B (level
3). Ports Ethernet 1/0/1 through Ethernet 1/0/4 of every device belong to VLAN 100, and the MAs in
the two MDs all serve VLAN 100.
In MD_A, there are three edge ports: Ethernet 1/0/1 on Device A, Ethernet 1/0/3 on Device D, and
Ethernet 1/0/4 on Device E; configure inward-facing MEPs on these ports respectively. In MD_B,
there are two edge ports: Ethernet 1/0/3 on Device B and Ethernet 1/0/1 on Device D; configure
outward-facing MEPs on the two ports respectively.
In MD_A, Device B is designed to have MIPs when its port is configured with low level MEPs. In this
case, port Ethernet 1/0/3 is configured with MEPs of MD_B, and the MIPs of MD_A can be
configured on this port. Based on the design, you should configure the MIP generation rule of
MD_A as explicit.
The MIPs of MD_B are designed on Device C, and are configured on all ports. Based on this
design, you should configure the MIP generation rule as default.
Configure CC to monitor the connectivity among all the MEPs in MD_A and MD_B. Configure to
use LB to locate link faults or use LT to identify the paths between source and destination MEPs or
locate faults after the whole network status is obtained.
