Hi, I have a problem with configuring HSRP/VRRP/GLBP in multiple network. I don't know how to configure with different network, all I know is configure in same network. Can someone help me? I don't know what to do. Thanks.
note: in the topology, L3 Switch is actually L2 Switch.

How do you mean 'with different network'?
I am not sure what you mean by this.

When configure HSRP/VRRP/GLBP we use same virtual gateway that is in same network. For example, I have network address 192.168.40.0/24 and the virtual gateway is 192.168.40.254
But when I create VLAN, I have different network each VLAN. That means I have different virtual gateway too.

How are your L3 interfaces configured on the Routers, are they an SVI or a subinterface?
In order to do HSRP for each vlan, you just duplicate the config for each of them but use a different group number and different virtual ip address.

that's what I want to know. SVI or subinterface.

Looking at your diagram, you are using it on GNS3. But can you confirm whether this is a production set up?
Again if you are using routers as your L3 gateway's i do not think you have the luxury of using SVI interfaces on them and you may have to create sub interfaces for each vlan you have. I am quite not sure how many you can create though.
Hope this helps.
Thanks,
Madhu.
