A standby router refers to any router in the HRSP group that is not currently serving as the active router. The standby router is ready to take over the role of the active router in case it fails or becomes unavailable. It essentially acts as a backup, ensuring continuous network connectivity and minimizing downtime.

VRRP (Virtual Router Redundancy Protocol) ensures immediate and transparent recovery from first-hop failures even when using equipment from multiple vendors. VRRP allows multiple routers to work together as a single virtual router, with one router acting as the master and the others as backups. In the event of a first-hop failure, the backup router immediately takes over as the master, ensuring uninterrupted connectivity. VRRP is a standardized protocol that is supported by various vendors, making it a reliable choice for network redundancy.

GLBP (Gateway Load Balancing Protocol) is the best choice for load balancing redundant gateways. It allows multiple routers to work together in a group, providing load sharing and redundancy. GLBP uses a virtual IP address that is shared among the routers in the group, and it also distributes the traffic load across the routers using a round-robin algorithm. In case one router fails, GLBP automatically redirects the traffic to the remaining active routers, ensuring high availability and efficient load balancing. VRRP (Virtual Router Redundancy Protocol) and HSRP (Hot Standby Router Protocol) are also used for gateway redundancy but do not provide load balancing capabilities like GLBP. GVRP (GARP VLAN Registration Protocol) is unrelated to load balancing redundant gateways.

GLBP (Gateway Load Balancing Protocol) allows up to four routers to actively forward traffic in a GLBP group. This protocol is used to balance the traffic load across multiple routers, providing redundancy and improving network performance. By allowing four member routers to forward traffic, GLBP ensures that the network can handle higher traffic loads and provides fault tolerance in case any of the routers fail.

The HSRP (Hot Standby Router Protocol) is a network protocol used for providing redundancy and high availability in a network. In HSRP, routers are grouped into a standby group, and one router is elected as the active router while the others are in standby mode. The active router handles the network traffic, while the standby routers are ready to take over in case the active router fails. The "Broadcast" state is not an HSRP state. The HSRP states are "Initial," "Active," and "Speak," which represent different stages in the protocol's operation.

Assigning a priority of 200 to the other router would make it more likely to be the active router in the HRSP group. In HSRP, the router with the highest priority becomes the active router. By setting the priority of the second router to 200, it would have a higher priority than the default priority (which is usually 100), increasing its chances of becoming the active router.

Based on the given information, router B will become the master virtual router for the group. This is because VRRP (Virtual Router Redundancy Protocol) uses a priority system to determine which router becomes the master. The router with the highest priority value becomes the master. In this case, router B has the highest priority value among routers A, B, C, and D. Therefore, router B will become the master virtual router for the group.

An HSRP router would be in the "Active" state if it is answering for the virtual IP address. In this state, the router is actively participating in the HSRP group and is responsible for forwarding traffic to the virtual IP address. The Active router is the one that is currently serving as the default gateway for the hosts in the network.

In HSRP with default timer values, a standby router takes 10 seconds to detect the loss of the active router. HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol used for providing redundancy in a network by allowing multiple routers to work together as a virtual router. The standby router constantly monitors the active router by sending hello messages every 3 seconds. If the standby router doesn't receive a hello message from the active router for 10 seconds, it assumes that the active router is down and takes over as the new active router.

The virtual MAC address 0000.5e00.01ff is used by VRRP group 255. VRRP (Virtual Router Redundancy Protocol) is a protocol that allows multiple routers to work together as a single virtual router, providing redundancy and failover. Each VRRP group is identified by a virtual MAC address, and in this case, group 255 is associated with the given MAC address.

HSRP (Hot Standby Router Protocol) uses UDP (User Datagram Protocol) to deliver messages to the HSRP group. UDP is a connectionless protocol that provides a lightweight and fast method of communication. It is commonly used for applications that require low latency and do not require the reliability and error-checking mechanisms provided by TCP. HSRP uses UDP for the exchange of hello messages and other control messages between routers in the HSRP group, allowing them to elect a standby router and provide redundancy in case of a failure.

The client PC should use 192.168.199.2 as its default gateway because the standby 1 ip command configures the switch interface with this IP address.

The active router possesses the virtual router MAC address, which is unique to the HSRP group. This MAC address is used by other devices on the network to communicate with the active router. The other HSRP members do not have this virtual MAC address until the active router fails or is shut down, at which point a new active router is elected and assigned the virtual MAC address.

AVG stands for Active Virtual Gateway. In GLBP (Gateway Load Balancing Protocol), AVG is responsible for answering ARP (Address Resolution Protocol) requests. When a host sends an ARP request to resolve a MAC address for a specific IP address, the AVG in GLBP responds with the virtual MAC address of the active virtual gateway. This allows for load balancing and redundancy in a network by distributing traffic across multiple gateways.

Multilayer switches share the IP address when running HSRP. HSRP (Hot Standby Router Protocol) is a redundancy protocol used to provide high availability in a network. When multiple switches are configured to run HSRP, they share a virtual IP address. This IP address is used as the default gateway for hosts in the network. If one switch fails, another switch takes over the virtual IP address to ensure uninterrupted communication. Therefore, the IP address is shared among the switches running HSRP to provide redundancy and fault tolerance.

The STP hello timer should be set to 3 seconds in order to align with the default values of the HRSP timers.

The default advertisement of the VRRP master router is 1 second. This means that the master router sends out advertisements every 1 second to inform the other routers in the VRRP group of its status as the master. This allows the other routers to know that the master router is still active and functioning properly.

Host A will receive the MAC address aaa.aaa.aaa2 in the ARP reply message. This is because GLBP uses a round-robin algorithm to assign virtual MAC addresses to hosts. Host B has already been assigned the virtual MAC address aaa.aaa.aaa1, so the next available virtual MAC address is aaa.aaa.aaa2. When Host A sends an ARP request for the MAC address of its default gateway, it will receive the virtual MAC address aaa.aaa.aaa2 in the ARP reply message.

The HSRP group that uses the MAC address 0000.0c07.ac11 is group 17.

If R1's Fa0/0 interface goes down, R1 will no longer be able to send hello messages to R2, causing R2 to declare itself as the active router. This is because R2 will not receive any hello messages from R1, which is a requirement for R1 to remain as the active router. Therefore, R2 will become the active router in this scenario.
