Hi Experts,
This may sound to be a very basic question but just came across when surfing through the website.
1. can we configure mutliple Virtual IP's in VRRP / HSRP / GLBP ? if so how many?
2. Any use case for configuring Multiple virtual IP's ?

1. Yes, you can configure all of them simultaneously.
2. VRRP and HSRP do not have embedded load-balancing. You may use multiple virtual IPs to load balance traffic in these protocols.

Hi Sergey,
Thanks for your response. sorry if my question wasn't clear.
I meant to ask....
interface FastEthernet0/0
ip address 10.10.10.1 255.255.255.0
duplex auto
speed auto
standby 1 ip 10.10.10.121
standby 1 ip 10.10.10.122 secondary
standby 1 ip 10.10.10.123 secondary
standby 1 priority 150
standby 1 preempt
here 122 and 123 are secondary Virtual Ip's Just curious to know what could be the purpose of this? and how many like this we could configure?

Sorry for my miunderstanding...
This thing is analogue of secondary IP not more, not less. What if you have a number of addresses assigned to interface (VLAN, subif, ...) and need to make them redundant? It is for that case.

Sure. Imagine you have a router and it is configured like this
interface g0/0
ip address 10.10.10.121 255.255.255.0
ip address 10.10.10.122 255.255.255.0 secondary
ip address 10.10.10.123 255.255.255.0 secondary
and all these IPs are default gateways for somebodies.
Next, you wish to create HSRP for acieving redundancy. What to do? Well... You create HSRP with secondaries and voila
