100 Each routing table entry contains a destination (the desired final destination),
138 Routing redirect control messages are used to dynamically
139 modify existing routing table entries as well as dynamically
140 create new routing table entries. On hosts where exhaustive
141 routing information is too expensive to maintain (e.g. work

144 messages can be used to provide a simple routing management
148 Statistics are kept by the routing table routines
149 on the use of routing redirect messages and their
150 affect on the routing tables. These statistics may be viewed using

159 Routing table interface
161 A protocol accesses the routing tables through

182 The routine \fIrtredirect\fP is called to process a routing redirect

193 User level routing policies
195 Routing policies implemented in user processes manipulate the
196 kernel routing tables through two \fIioctl\fP calls. The
197 commands SIOCADDRT and SIOCDELRT add and delete routing entries,

207 Several routing policy processes have already been implemented. The
209 ``routing daemon'' uses a variant of the Xerox NS Routing Information
210 Protocol [Xerox82] to maintain up-to-date routing tables in our local
211 environment. Interaction with other existing routing protocols,
