A USG standby scenario is shown in Figure. The service interface works in three steps, down the line connecting the router through an administrator to view, USG_A status is H RP_M [USG A], USG_B state HRP_S [USG_B ], but all the traffic is not completely passing through USG_A, half of the traffic also passes via USG_B. Which of the following configuration command can solve this problem? [USG_A] interface GigabitEthernet 0/0/1 [USG_A-GigabitEthernet 0/0/1] hrp track master [USG_A] interface GigabitEthernet 0/0/3 [USG_A-GigabitEthernet 0/0/3] hrp track master [USG_A] ospf 101 [USG_A-ospf -101] area 0 [USG_A-ospf-101-area-0.0.0.0] network 10.104.10.0 0.0.0.255 [USG_A-ospf-101-area-0.0.0.0] network 10.104.30.0 0.0.0.255 [USG_A] hrp interface GigabitEthernet 0/0/2 [USG_B] interface GigabitEthernet 0/0/1 [USG_B-GigabitEthernet 0/0/1] hrp track slave [USG_B] interface GigabitEthernet 0/0/3 [USG_B-GigabitEthernet 0/0/3] hrp track slave [USG_B] ospf 101 [USG_B] ospf 101 [USG_B-ospf -101] area 0 [USG_B-ospf-101-area-0.0.0.0] network 10.104.10.0 0.0.0.255 [USG_B-ospf-101-area-0.0.0.0] network 10.104.30.0 0.0.0.255 [USG_B] hrp interface GigabitEthernet 0/0/2
