ip overlapping query

[marcusbrutus]

Hi. I just have another novice question.

I tried to set a router port with an ip add of 10.0.0.1/19 and another port of the same router with an ip add of 10.0.16.1/20. I kept on receiving an error msg indicating that the second ip add overlaps with the first one. Subnet-zero is enabled. Can anyone please explain why this is so? Thanks in advance to anyone who could clarify this for me.

Because they are overlapping addresses and you cannot do this on a router.

10.0.0.0/19

/19 = 255.255.224.0 so

network range is 10.0.0.1 -> 10.0.31.254

This overlaps with 10.0.16.1.
