a funny thing happned ,when i config a ip address on a interface.the system log in last line suggest that is illegal address.

i know is a network address and can't be used like that.can anyone tell me,why and can be assigned to the interface.

R1(config-if)# ip address

Unless there is a typo it is your subnet mask that is giving the error message ie. should be is not a network address, that would be

Hi Friend,

IP address and are valid address because their subnet range start from - out of which is the first address and for second ip address subnet range is - out of which is again the first address.

But you last address with mask is wrong because is not a valid mask and if you use with mask like you used for other it should work fine.
