Hello ITPro TV ! I have a question that came up after working with DHCP in my lab.. Working from the CCENT course 100-105 specifically. I have a router setup with the following DHCP config.
ip dhcp excluded-address 192.168.80.1 192.168.80.99
ip dhcp pool 192.168.80.0
network 192.168.80.0 255.255.255.0
ip dhcp pool 192.168.80.144
host 192.168.80.144 255.255.255.0
Things seemed to be working great until I configured the 2nd scope to test DHCP reservations. For some reason the PC that is supposed to get the 192.168.80.144 address still seems to obtain an address out of the general scope. Here is the output of the "show ip dhcp binding" command:
R2#show ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
192.168.80.100 0168.f728.786e.b2 Oct 11 2016 01:47 PM Automatic
192.168.80.144 68f7.2878.6eb2 Infinite Manual
Notice how the the same MAC has 80.100, but the system added this funny "01" to the front of the MAC.. If I do a clear ip dhcp binding on the 80.100 address,. then ipconfig /release - /renew on the client it just keeps gettting the 80.100 address.
Thanks for clarifying where I went wrong!
