A network administrator is configuring HSRP on a router's GigabitEthernet0/0 interface, which has been assigned the physical IPv4 address . The administrator enters the command `standby 1 ip 192.168.10.1` under the interface configuration mode. What issue does this configuration introduce?
- It configures the HSRP virtual IP address to match a physical interface IP address, which is invalid in HSRP.Cevap
- BIt creates a broadcast domain conflict by forcing the interface to forward all frame traffic to a multicast MAC address.
- CIt overrides the longest prefix match rule in the IPv4 routing table for all connected networks.
- DIt automatically converts the HSRP group into a floating static route with an administrative distance of 255.
Cevap
Assigning the physical interface IPv4 address as the HSRP virtual IP address is an invalid configuration because HSRP requires the virtual IP to be a separate, distinct IP address within the subnet.
In Cisco Hot Standby Router Protocol (HSRP), the virtual IP address shared by the group must be a unique IP address on the local subnet that is not assigned to any router's physical interface. Attempting to assign a router's physical IP address as the HSRP virtual IP address is invalid and prevents proper operation.
