on my hardware i have to enter the subnet mask as decimal,eg 255.255.255.252- as opposed to the cidr notation /30.
Hope this helps

Yeah, there is only a few areas in the IOS where you can use CIDR

thank you i will give it a shot see what happens

10.0.0.0 is not the first usable ip in that network which would be a separate error, but the main problem is that that is not the correct way to enter a netmask in ios, dotted decimal format is what it's looking for

10.0.0.0/30 will have a network address of 10.0.0.0 -not usable on an interface, 10.0.0.1, 10.0.0.2 and a broadcast address of 10.0.0.3-also unuseable.

Using this fine gentlemans breakdown, configure it like this

RanetA(config-if)#ip address 10.0.0.1 255.255.255.252

Tada!
