a3ComRoutePolicyProtocolType
1.3.6.1.4.1.43.29.4.23.1.1.2
This mandatory object defines the protocol in which a policy will
be used. Once such protocol family is defined, the agent will use
this information to parse the source, route, as well as all other
objects that apply.
Once a policy entry is successfully made active(1), this object
may not be modified. If the protocol chosen is not supported by
the agent or is set to undefined(1), an error is returned.
