Which Cisco IOS XR configuration is missing to complete the configuration task of enabling BFD with only the OSPF peer over the gi0/3/0/1 interface in area 0?
| A. |
bfd fast-detect also needs to be enabled globally under router ospf 100.RP/0/RSP0/CPU0:P1(config-ospf)#bfd fast-detect | |
| B. |
bfd fast-detect also needs to be enabled for the OSPF area under area 0.RP/0/RSP0/CPU0:P1(config-ospf-ar)#bfd fast-detect | |
| C. |
bfd fast-detect also needs to be enabled for the OSPF interface under area 0 interface gi0/3/0/1.RP/0/RSP0/CPU0:P1(config-ospf-ar-if)#bfd fast-detect | |
| D. |
bfd fast-detect also needs to be enabled globally on the router.RP/0/RSP0/CPU0:P1(config#bfd fast-detect | |
| E. |
bfd fast-detect also needs to be enabled on the gi0/3/0/1 interface under interface gi0/3/0/1.RP/0/RSP0/CPU0:P1(config-if)#bfd fast-detect |
To enable Bidirectional Forwarding Detection (BFD) to detect failures in the path between adjacent forwarding engines, use the bfd fast-detect command in the appropriate configuration mode. To return the software to the default state in which BFD is not enabled, use the no form of this command.
