HSRP vs VRRP vs GLBP : Spot the difference

As I already told you about that i will come up with the comparison between the three protocols named as HSRP, VRRP and GLBP. I already discussed one by one all these protocols in details. Although i will cover the configurational part in later stage.

Here, in this article i only cover the difference between all these above mentioned protocol, so that you can compare these protocols and design your network accordingly with the need and demand from your enterprise network. I knew generally in the enterprise network you can only use VRRP or HSRP but you can use GLBP because actually load balancing is done by GLBP not with these HSRP and VRRP protocol.

With the use of HSRP, you can have multiple active and standby router on the basis of VLAN. Lets take an example, If i have 4 different VLANs, one is VLAN 2 ,VLAN 3, VLAN 4 and VLAN 5. I have 2 routers R1 and R2. I can manage my traffic with the following options :

• For VLAN2 : R1 is active and R2 is standby router
• For VLAN3 : R2 is active and R1 is standby router
• For VLAN4:  R1 is active and R2 is standby router
• For VLAN5 : R2 is active and R1 is standby router

In this way i can manage my traffic for different VLANs in HSRP. 

For GLBP it is different, the traffic is flowing 4 ways

• None
• Weighted
• Host dependent
• Round-Robin

I just touched the way how traffic is routed in the network and it is only the manual configuration part by which administrator can handle the management of the traffic.

Below table is showing the difference between these protocols.
