router bgp 64500 bfd multiplier 2 bfd minimum-interval 20 address-family ipv4 unicast network 10.1.1.0/24 ! address-family ipv6 unicast ! neighbor 192.168.1.1 remote-as 65001 address-family ipv4 unicast ! end
Which configuration is missing to complete the configuration task of enabling BFD with the 192.168.1.1 EBGP peer?

A. bfd fast-detect also needs to be enabled globally under router bgp 64500
RP/0/RSP0/CPU0:P1(config-bgp)#bfd fast-detect
B. bfd fast-detect also needs to be enabled for the address-family under address-family ipv4 unicast
RP/0/RSP0/CPU0:P1(config-bgp-af)#bfd fast-detect
C. bfd fast-detect also needs to be enabled for the 192.168.1.1 neighbor under neighbor 192.168.1.1
RP/0/RSP0/CPU0:P1(config-bgp-nbr)#bfd fast-detect
D. bfd fast-detect also needs to be enabled for the 192.168.1.1 neighbor address-family under neighbor 192.168.1.1 address-family ipv4 unicast
RP/0/RSP0/CPU0:P1(config-bgp-nbr-af)#bfd fast-detect
E. bfd fast-detect also needs to be enabled globally on the router
RP/0/RSP0/CPU0:P1(config)#bfd fast-detect
