[LAN] SLAC's Policy on Connection of Multi-homed Hosts

Last Update: April 15, 1998
SLAC: [ The Lab | Index | Phone Dir. | Network Group
Multi-homed hosts are becoming increasingly common, making it possible to connect a host to more than one subnet simultaneously. This type of configuration provides a number of advantages including better throughput, reduced routing overhead and (possibly) secure communication between sensative networks through a trusted host. However, although the connection of a multi-homed host might be quite innocent and with the best intentions, it can lead (and has been observed at SLAC) to disasterous results for the network as a whole if it is configured incorrectly. In particular a multihomed host acting as a router has the potential to cause unwanted traffic possibly denying service to many users.

Please read the guidelines below before connecting a multi-homed host to the SLAC LAN.
