Refer to the exhibits.
Exhibit 1
Exhibit 2
Switch-1 and Switch-2 lost IP connectivity with each other. They did not detect the issue for several seconds and caused a temporary traffic disruption. The administrations expected failover to the backup route through Switch-3 to occur in less than a second. The administrators restore the failed link and view the output on Switch-1, shown in the exhibit.
What should they do to create the expected behavior if connectivity is lost again?
A . Lower the hello timer to a given range of times on each OSPF routing switch in VLAN 100
B . Enable BFD in asynchronous mode on each OSPF routing switch in VLAN 100
C . Manually configure the network type as point-to-point on each OPSF routing switch in VLAN 100
D . Set a BFD echo source IP address on each OSPF routing switch in VLAN 100
Answer: B
