Saravanamurthy,
I am afraid this is something you cannot easily disable as there is no option for that in Express GUI.
However, it is enabled in Express profiles
vx9000-E29E5E#show running-config profile ap7522 default-ap7522 include-factory ip routing Only way would be to use customized startup configuration uploaded to the AP, but this is not recommended / supported as it may violate pre-configured Express objects.

Ondrej
