Description (partial)

unable to configure sub-interface. If for any interface we create two sub interfaces, and once we try to configure those two sub-interfaces it throws an error "interface in2"sub interface" has already been configured.

Configure the sub-interfaces and add them to OSPF.

For e.g: If we have sub-interfaces of Gig 1.1 and 1.2 and we want to use both for OSPF, if we configure 1.1 first and then try to configure 1.2 it throws the error; "Interface <name> has already been configured for the protocol ospf in the object <name>"

 But we can configure both when we take bottom up approach that's we have to configure 1.2 first and then we will configure 1.1
