Assign multi IP address at the same interface at router

[machiasiaweb]

Hi,

Is it possible to assign multi IP address to the same interface at router and what should be command.  As I only find some configuration example which is configure 2 ip address for the same interface.

Thx!

Hi,

You can configure only one primary address and as many secondary addresses as you want up to hw/sw platform limit.

Regards.

Yes, I found this example also.  Is that means

interface GigabitEthernet0/0

ip address 10.10.10.10 255.255.255.0

ip address 20.20.20.20 255.255.255.0 secondary

ip address 30.30.30.30 255.255.255.0 secondary

....

....

Is it Correct?
