how many it is available?

I know that the secondary IP address feature allows the multiple address

to be configured under the same interface Vlan. In case of the following Vlan configuration, is it possible?

or is it limited?

Hi,

As such there is not limit for configuring the secondry IP address on an interface. Depends on the memory and processing. The MAX number of HSRP group supported is 256 but on different platofrms there is a limitaion such as SUP2/MSC2 supports 16 HSRP group. So depends on whihc platform u r using it. If the group number are supported it will work.

However you have to change this config. For the secondry standby IP address the command used is " standby 72 ip x.x.72.254 secondry "

HTH,
