3. 配置BFD Session
   [PE1]bfd
   [PE1]bfd pe1tope3 bind peer-ip 10.1.2.5 interface Vlanif 20
   [PE1-bfd-session-pe1tope3]discriminator local 1
   [PE1-bfd-session-pe1tope3]discriminator remote 2
   [PE1-bfd-session-pe1tope3]commit
   [PE3]bfd
   [PE3]bfd pe3tope1 bind peer-ip 10.1.2.3 interface Vlanif 20
   [PE3-bfd-session-pe3tope1]discriminator local 2
   [PE3-bfd-session-pe3tope1]discriminator remote 1
   [PE3-bfd-session-pe3tope1]commit

4. 配置BFD和接口联动
   [PE1]oam-mgr
   [PE1-oam-mgr]oam-bind ingress bfd-session 1 trigger if-down egress interface GigabitEthernet 0/0/1
   [PE3]oam-mgr
   [PE3-oam-mgr]oam-bind ingress bfd-session 2 trigger if-down egress interface g0/0/2

5. 检查配置
   [PE3-GigabitEthernet0/0/1]shutdown
