What problem does a first-hop redundancy protocol address?
Back
An FHRP lets multiple routers share a virtual gateway so another router can take over if the forwarding router fails.

02
Front
Which gateway address should hosts use in an FHRP group?
Back
Hosts use the shared virtual gateway address as their default gateway, rather than either router’s physical address.
03
Front
What does FHRP not guarantee beyond gateway redundancy?
Back
FHRP does not ensure that a router has a working path beyond the LAN; routes still come from static routing or a routing protocol.
04
Front
What roles does HSRP elect?
Back
HSRP elects an active router and a standby router for a virtual IP address.
05
Front
What are VRRP’s router roles, and which IP versions does it support?
Back
VRRP elects an Active Router and backups for a virtual router; it supports IPv4 and IPv6.
06
Front
What distinguishes GLBP’s forwarding behavior?
Back
GLBP provides gateway redundancy and can share host traffic among multiple forwarding routers.
07
Front
How many HSRP or VRRP virtual gateways are generally active on one LAN at a time?
Back
With HSRP or VRRP, a single virtual gateway is generally active on a LAN at a time.
08
Front
How can HSRP or VRRP share load across subnets?
Back
Different HSRP or VRRP groups or virtual gateways can be configured for different subnets.
09
Front
In the HSRP example, why is R1 the preferred active router?
Back
R1 is preferred because its priority is 110, higher than R2’s priority of 100.
10
Front
What does HSRP preemption allow?
Back
Preemption lets a higher-priority router reclaim the active role when it returns.
11
Front
What does HSRP tracking do when a tracked object fails?
Back
Tracking lowers a router’s priority when the tracked object, such as an uplink interface, fails.
12
Front
Which command checks HSRP group state briefly?
Back
Use `show standby brief` on both routers to check the group state, roles, virtual IP, and group.
