R3102-R3103-HP 6600/HSR6600 Routers High Availability Configuration Guide

29
 MD_A has three edge ports: GigabitEthernet 3/0/1 on Router A, GigabitEthernet 3/0/3 on
Router D, and GigabitEthernet 3/0/4 on Router E. They are all inward-facing MEPs. MD_B has
two edge ports: GigabitEthernet 3/0/3 on Router B and GigabitEthernet 3/0/1 on Router D.
They are both outward-facing MEPs.
 In MD_A, Router B is designed to have MIPs when its port is configured with low level MEPs. Port
GigabitEthernet 3/0/3 is configured with MEPs of MD_B, and the MIPs of MD_A can be
configured on this port. Configure the MIP generation rule of MD_A as explicit.
 The MIPs of MD_B are designed on Router C, and are configured on all ports. 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 LB
to locate link faults.
 After the status information of the entire network is obtained, use LT to detect link faults.

Configuration procedure
1. Configure a VLAN and assign ports to it:
On each device shown in Figure 6, create VLAN 100 and assign all ports to VLAN 100.
2. Enable CFD:
# Enable CFD on Router A.
<RouterA> system-view
[RouterA] cfd enable
Enable CFD on Router B through Router E using the same method.
3. Configure service instances:
# Create MD_A (level 5) on Router A, create MA_A, which serves VLAN 100, in MD_A, and
create service instance 1 for MD_A and MA_A.
[RouterA] cfd md MD_A level 5
[RouterA] cfd ma MA_A md MD_A vlan 100
[RouterA] cfd service-instance 1 md MD_A ma MA_A
Configure Router E as you configure Router A.
