3 major FHRP protocols

1. HSRP
2. VRRP
3. GLBP

2

What does GLBP stand for?

Gateway Load Balancing Protocol

3

What does FHRP stand for?

First Hop Redundancy Protocol

4

What does VRRP stand for?

Virtual Router Redundancy Protocol

5

What does HSRP stand for?

Hot Standby Router Protocol

6

How does HSRP implement loadbalancing?

By allowing different routers be the active router for different subnets.

7

What's the biggest difference between GLBP and HSRP/VRRP?

GLBP uses an active/active model, so traffic can be distributed between multiple routers even if the hosts are in the same subnets.

8

What function does the AVG perform?

In GLBP, the AVG replies to all ARP requests for the virtual IP address. It will LB the responses so that the hosts end up balanced between all the routers in the group.

9

What does AVG stand for?

Active Virtual Gateway

10

How does the AVG direct hosts to utilize different routers as their gateways?

By providing the MAC addresses of different routers in the LB group for the virtual IP address.

11

HSRP syntax to set up the VIP for a LB group

conf t
interface gi1/0
standby *group #* ip *VIP*

12

5 basic HSRP attributes that can be configured under an interface

1. VIP
2. Group name
3. Priority
4. Version
5. Preempt

13

HSRP syntax to set priority for a LB group

conf t
interface gi1/0
standby *group #* priority *priority value*

14

For HSRP, what is the default priority?

100

15

For HSRP, what is the priority range?

1 - 255

16

For HSRP, is a higher or lower priority better?

Higher

17

HSRP syntax to return an interface to active state after it comes back up

conf t
interface gi1/0
standby *group #* preempt

18

2 commands to show detailed HSRP status

show standby
show standby brief

19

GLBP syntax to configure the virtual IP

glbp *group #* ip *vip*

20

GLBP syntax to configure the name of the LB group

glbp *group #* name *name*

21

How does GLBP's priority system differ from that of HSRP?

It doesn't. Same defaults and priority range, along with the fact that higher priority is better.

22

How does a router become a GLBP AVG?

It has the higher priority and either comes online first, or has preemption enabled.

23

2 commands to show the status of GLBP

show glbp
show glbp brief

24

What is the GLBP term for a router that is active in a LB group?

A forwarder
