Routing and Switching

1. Network requirements
   • • configure a static route on Switch A can reach 120.1.1.0/24 network segment, configure a static route on Switch B can to
   reach 121.1.1.0/24 network segment, and are enabled with BFD detection.
   • • configure a static route on Switch C can reach 120.1.1.0/24 and 121.1.1.0/24 network segment.
   • • When Switch A and Switch B over link L2 Switch failure in communication, the BFD can detect, and the cut
   switch to communicate Switch C.

   Device Interface IP address Interface IP address Device
   Switch of Vlan-A-INT11 INT10 12.1.1.1/24 of Vlan 10.1.1.102/24
   Switch-B of Vlan of Vlan-INT13 INT10 12.1.1.2/24 13.1.1.1/24
   Switch INT11-C of Vlan 10.1 .1.100 / 24 Vlan-int13 13.1.1.2/24

3. Step Configuration
   (1) Configuration of IP addresses of each interface (omitted)
   (2) configure static routes and BFD
   # configure static routes on Switch A Enable BFD function, bidirectional detection.
   <SwitchA> System-View
   [SwitchA] interface VLAN-interface 10
   [SwitchA-VLAN-interface10 For] BFD min-TRANSMIT-interval The 500
   [SwitchA-VLAN-interface10 For] BFD min-the receive-interval The 500
   [SwitchA-VLAN-interface10 For] BFD . 9-multiplier The Detect

   [SwitchA] IP-route-static VLAN interface 120.1.1.0. 11 24 10.1 65 by the preference .1.100
   [SwitchA] quit
   # configure static routes on Switch B, and enable BFD function, bidirectional detection.
   <SwitchB> System-View
   [SwitchB] interface VLAN-interface 10
   [SwitchB-vlan-interface10] bfd min-transmit-interval 500
   [SwitchB-vlan-interface10] bfd min-receive-interval 500

   [SwitchB-vlan-interface10] quit
   [SwitchB] ip route-static 121.1.1.0 24 vlan-interface 10 12.1.1.1 bfd control-packet
   [SwitchB] ip route-static 121.1.1.0 24 vlan-interface 13 13.1.1.2 preference 65
   [SwitchB] quit
   #在 Switch C 上配置静态路由。
   <SwitchC> system-view
   [SwitchC] ip route-static 120.1.1.0 24 13.1.1.1
