Which two statements are true about the output from the show standby vlan 50 command?
(Choose two.)
A.
multipoint control unit (MCU) Catalyst_A.
B.
Hosts using the default gateway address of 192.168.1.1 will have their traffic sent to
192.168.1.11 even after Catalyst_A becomes available again.
C.
Hosts using the default gateway address of 192.168.1.2 will have their traffic sent to
Catalyst_A.
D.
Catalyst_A is load sharing traffic in VLAN 50.
Explanation:
HSRP uses a priority scheme to determine which HSRP-configured router is to be the
default active router. To configure a router as the active router, you assign it a priority that is
higher than the priority of all the other HSRP-configured routers. The default priority is 100,
so if you configure just one router to have a higher priority, that router will be the default
active router.
HSRP works by the exchange of multicast messages that advertise priority among HSRPconfigured routers. When the active router fails to send a hello message within a
configurable period of time, the standby router with the highest priority becomes the active
router. The transition of packetforwarding functions between routers is completely transparent to all hosts on the network.
HSRP-configured routers exchange three types of multicast messages:
• Hello—The hello message conveys to other HSRP routers the router’s HSRP priority and
state information. By default, an HSRP router sends hello messages every three seconds.
• Coup—When a standby router assumes the function of the active router, it sends a coup
message.
• Resign—A router that is the active router sends this message when it is about to shut
down or when a router that has a higher priority sends a hello message.
At any time, HSRP-configured routers are in one of the following states:
• Active—The router is performing packet-transfer functions.• Standby—The router is prepared to assume packet-transfer functions if the active router
fails.
• Speaking and listening—The router is sending and receiving hello messages.
• Listening—The router is receiving hello messages.
The standby preempt interface configuration command allows the router to become the
active router when its priority is higher than all other HSRP-configured routers in this Hot
Standby group. The configurations of both routers include this command so that each router
can be the standby router for the other router. The 1 indicates that this command applies to
Hot Standby group 1. If you do not use the standby preempt command in the configuration
for a router, that router cannot become the active router.
