Your network of 172.1.88.0 255.255.224.0 will attempt to include the
172.1.89.0 network too (subnet 172.1.64.0, host from 172.1.64.1, Host to
172.1.95.254 with broadcast address 172.1.95.255), which happens to be
alread configured for the first interface.

Subject: Ip address overlaps with VLSM
I am trying to give a ip add to two different
interface with different mask
S0
R1(config-if)#ip address 172.1.89.1 255.255.225.0
S1
R1(config-if)#ip address 172.1.88.1 255.255.224.0
******* 172.1.64.0 overlaps with Serial0 ********
( ****** the output that I get as u put in the command
********)
now I know the network address is 64 and the network
first 3 bit are 010
that is same to the s0 first 3 bit 010
I try it wth all the address that have the first 3
bit different and it works
S1
R1(config-if)#ip address 172.1.96.1 255.255.224.0
And it works the first 3 bit = 011
Know some how I am not able to understand why is it
doing so when I am using different mask
The network address is also no all 0000000 so it
cannot be the ip subnet-zero thing
But there is some thing got to do with the same
network bits with a different mask
What is it can some one help me on this
I am spending a lot of time on things like this
would it pay back ?
Thank u
Bhisham
