Which value to use in HSRP protocol election process?
Click on the arrows to vote for the correct answerA. B. C. D.
HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol that is used to provide redundancy in a network by allowing multiple routers to participate in a virtual IP address for a single gateway. HSRP routers communicate with each other using multicast hello messages to determine the active router and the standby router. The election process is based on a set of criteria that determines which router should become the active router and which should become the standby router.
The values used in the HSRP protocol election process are:
A. Interface: Each HSRP group is associated with a specific interface on the router. The interface with the highest IP address becomes the active router, and the other routers become standby routers.
B. Virtual IP address: The virtual IP address is the IP address that is used as the gateway address by hosts on the network. The router with the highest priority is selected as the active router for the virtual IP address.
C. Priority: The priority is a numeric value that is assigned to each router participating in the HSRP group. The router with the highest priority becomes the active router. The default priority value is 100, and the range is 0 to 255.
D. Router ID: The router ID is a unique identifier for each router participating in the HSRP group. The router with the highest router ID becomes the active router. If the router ID is not manually configured, it is derived from the highest IP address of the router's loopback interfaces.
In summary, the HSRP protocol election process considers multiple criteria, including the interface, virtual IP address, priority, and router ID, to determine which router becomes the active router and which routers become standby routers. The router that meets the highest priority criteria, which can be configured or derived, becomes the active router for the virtual IP address.
