A network engineer is configuring VRRPv2 on a Cisco IOS router to provide default gateway redundancy for hosts on a subnet. The physical interface GigabitEthernet0/0 is configured with the IP address . The engineer then executes the interface command `vrrp 10 ip 172.16.10.1`. What is the operational effect of configuring the VRRP virtual IP address to match the physical interface IP address?
- The router accepts the command and automatically sets its VRRP priority to 255, making it the IP address owner and Master router.Cevap
- BThe router rejects the command with an error message because virtual IP addresses must be distinct from physical interface IP addresses.
- CThe router accepts the command with the default priority of 100, but preemption must be manually enabled for it to become the Master router.
- DThe command is accepted into the running configuration, but virtual MAC address generation fails due to a protocol prefix mismatch.
Cevap
The router accepts the command and automatically sets its VRRP priority to 255, making it the IP address owner and Master router.
In VRRPv2/v3, a router can use its own physical interface IP address as the group virtual IP address. When configured this way, the router becomes the IP address owner, and its VRRP priority is automatically forced to 255 (the highest possible priority), ensuring it acts as the Master router.
