How is load balancing achieved when implementing HSRP?
A.
By configuring multiple gateways on the routers
B.
By using multiple HSRP groups
C.
By configuring the same priority on all HSRP group members
D.
By configuring multiple virtual router addresses
Explanation:
When implementing Hot Standby Router Protocol (HSRP), load balancing is achieved by using multiple HSRP
groups. Routers configured for HSRP can belong to multiple groups and multiple VLANs. By configuring one
group to be active for Router A and standby for Router B, and the second group to be active for Router B and
standby for Router A, both routers A and B can be used to pass traffic, as opposed to one sitting idle.
Load balancing cannot be achieved by configuring multiple gateways on the routers. The routers have one IP
address. Each group will have a virtual IP address. In the configuration below, line 4 configures the virtual IP
address, and is therefore the address that clients will use as their gateway:
interface fastethernet 0/1
no switchport
ip address 192.168.5.5 255.2555.255.0
standby 1 ip 192.168.5.10
Load balancing cannot be achieved by configuring the same priority on all HSRP group members. If that were
done, one of the routers would become active and the others would remain inactive standbys. The active router
will be the one with the highest IP address.
Load balancing cannot be achieved by configuring multiple virtual router addresses. Each HSRP group can only
have one virtual address.
