Configuring BFD for OSPF
Network requirements
As shown in Figure 49 :
• OSPF is enabled on Switch A, Switch B and Switch C that are reachable to each other at the
network layer.
• After the link over which Switch A and Switch B communicate through a Layer 2 switch fails, BFD
can quickly detect the failure and notify OSPF of the failure. Switch A and Switch B then
communicate through Switch C.

Device Interface IP address Device Interface IP address
Switch A Vlan-int10 10.1.0.102/24 Switch B Vlan-int10 10.1.0.100/24
Vlan-int11 11.1.1.1/24 Vlan-int13 13.1.1.1/24
Switch C Vlan-int11 11.1.1.2/24
Vlan-int13 13.1.1.2/24
Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown)
2. Configure OSPF basic functions.
