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
Explanation:
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.
bfd fast-detect [disable | ipv4]
no bfd fast-detect
