A network technician is configuring high availability on interface GigabitEthernet0/1 of a Cisco IOS router. The interface is currently assigned the physical IPv4 address . The technician enters the command `standby 1 ip 192.168.10.1` under interface configuration mode. Which outcome will occur as a result of executing this command?
- Cisco IOS rejects the virtual IP assignment because HSRP requires the virtual IP address to be distinct from any interface physical IP address in the group.Cevap
- BCisco IOS accepts the configuration, and the router automatically sets its priority to 255 to become the permanent IP address owner for HSRP group 1.
- CCisco IOS accepts the configuration, but HSRP hello packets are suppressed to prevent ARP table corruption on local LAN hosts.
- DCisco IOS accepts the configuration, but automatically disables preemption across all routers participating in HSRP group 1.
Cevap
Cisco IOS rejects the virtual IP assignment because HSRP requires the virtual IP address to be distinct from any interface physical IP address in the group.
In Cisco IOS HSRP implementations, the virtual IP address must be a unique IP address within the local subnet that is not configured as the physical IP address of any interface in the HSRP group. When an administrator attempts to assign an existing physical IP address as the HSRP virtual IP, Cisco IOS rejects the command with an error message.
