Network Protocols

routing daemon similar to the BSD routing daemon (routed) for its routing services. This daemon

uses Routing Information Protocol (RIP) messages to create routing tables. RIP messages are sent

by a gateway announcing that it provides the route to a destination. The routing tables created from

these RIP messages include entries for Internet gateways to hosts on other networks and to those

other networks.

In addition to RIP messages, the Model 5390 server can send ICMP redirects. Redirects are messages

sent via ICMP to announce that the expected route to a destination is not correct and to supply the

correct route.

Internet Trailer Packets

The Model 5390 server on an Ethernet supports the trailer packets used in 4.2BSD UNIX. Trailer

packets are not recommended, as they are more overhead for the Model 5390 server. A host uses

trailers for 512-byte blocks only.
