* The above AFI and SAFI definitions are for internal use. The protocol
|
|
* definitions (IANA values) as for example used in BGP protocol packets
|
|
* are defined below and these will get mapped to/from the internal values
|
|
* in the appropriate places.
|
|
* The rationale is that the protocol (IANA) values may be sparse and are
|
|
* not optimal for use in data-structure sizing.
|
|
* Note: Only useful (i.e., supported) values are defined below.
