Detailed Description

The MD5PacketRouteEntry4 may appear as the first route entry in a RIPv2 packet. It has the same size as an PacketRouteEntry<IPv4>. The address family has the special value 0xffff which imples authentication. The authentication type is overlaid in the route tag field and takes the special value 3. With MD5 the authentication data appears after the remaining route entries. Details are disclosed in RFC2082.

All items in the route entry are stored in network order. The accessor methods provide values in host order, and the modifiers take arguments in host order.

NB We describe the field labelled as "RIP-2 Packet Length" on page 5 of RFC 2082 as the "auth_offset". This matches the textual description in the RFC.
