Hi All,
Could you please tell me why would we use Two IP Addresses for an Interface - Primary and Secondary IP ?
Please explain scenarios, Advantages & Limitations ?
Thanks in Advance,

If your migrating to a new subnet on your LAN there very handy to use

As Mark has noted, secondaries can be very handy for network (prefix) migrations.
BTW, by default, Cisco devices, when using IP helpers, will only forward the primary IP.
