Hi there,
I am sure by now you have solved the issue but address overlaps notice pop up when you have configured wrong subnet mask. Check other sub interface mask and do the math.
If both interfaces are in one subnet mask, you will have this issue

Hi there
Can anyone please explain this strange behaviour?
If I try to put the ip address in one line at a time it spits it out:
R2#c Enter configuration commands, one per line. End with CNTL/Z. R2(config)#int s0/0.1 poi R2(config)#int s0/0.1 point-to-point R2(config-subif)#ip add R2(config-subif)#ip address 172.16.25.0 255.255.255.254 % 172.16.25.0 overlaps with Serial0/0.56 R2(config-subif)#^Z R2#
But if I cut and paste it in with the dlci command it’s OK!!!
R2#c Enter configuration commands, one per line. End with CNTL/Z. R2(config)# R2(config)#! R2(config)#interface Serial0/0.1 point-to-point R2(config-subif)# ip address 172.16.25.0 255.255.255.254 R2(config-subif)# frame-relay interface-dlci 25 R2(config-fr-dlci)#!
