Moy Standards Track [Page 226]
RFC 2328 OSPF Version 2 April 1998
D. Authentication
All OSPF protocol exchanges are authenticated. The OSPF packet
header (see Section A.3.1) includes an authentication type field,
and 64-bits of data for use by the appropriate authentication scheme
(determined by the type field).
The authentication type is configurable on a per-interface (or
equivalently, on a per-network/subnet) basis. Additional
authentication data is also configurable on a per-interface basis.
Authentication types 0, 1 and 2 are defined by this specification.
All other authentication types are reserved for definition by the
IANA (iana@ISI.EDU). The current list of authentication types is
described below in Table 20.
AuType Description
___________________________________________
0 Null authentication
1 Simple password
2 Cryptographic authentication
All others Reserved for assignment by the
IANA (iana@ISI.EDU)
