S2989G-24TX Operation Manual

Chapter 4 Routing Protocol Related Configuration

4-22

Switch(config)#interface vlan 15

Switch(config-if-vlan15)#ip address 15.1.1.1 255.255.255.0

Switch(config)#ip route 14.1.1.0 255.255.255.0 12.1.1.2 bfd

Switch B:

Switch#config

Switch(config)#interface vlan 12

Switch(config-if-vlan12)#ip address 12.1.1.2 255.255.255.0

Switch(config)#interface vlan 14

Switch(config-if-vlan15)#ip address 14.1.1.1 255.255.255.0

Switch(config)#ip route 15.1.1.0 255.255.255.0 12.1.1.1 bfd

When the link between Switch B and layer 2 switch is failing, Switch A can detect the

change of Switch B immediately, here the static routing is at inactive state.

4.5.3.2 Example for Linkage of BFD and RIP Route

Example:

Switch A and Switch B are connected and run RIP protocol, both of them enable BFD

function. When the link between Switch A and Switch B is failing, BFD can detect it

immediately.

Configuration procedure:

Switch A:

Switch#config

Switch(config)#bfd mode active

Switch(config)#interface vlan 100

Switch(config-if-vlan100)#ip address 10.1.1.1 255.255.255.0

Switch(config)#interface vlan 200

Switch(config-if-vlan200)#ip address 20.1.1.1 255.255.255.0

Switch(config)#router rip

Switch (config-router)#network vlan 100

Switch (config-router)#network vlan 200

Switch(config)#interface vlan 100

Switch(config-if-vlan100) #rip bfd enable
