I have seen on the core switch I am working on currently there is not the 'ip routing' statement.

Could this cause a problem ? or is it the software version not showing it into the config.
there is the ability to input this command.....
HOSTNAME(config)#ip routing ?

Hello Lewis,
ip routing may be the default in your IOS image.
There are few static routes configured and so IP routing is likely enabled.
to check if ip routing is enabled post the output of
show ip route.
The output of this show command is totally different with ip routing disabled.
If the ouput is the usual with entries corresponding to the static routes you are fine.
Hope to help
