Internet Router Discovery Protocol (IRDP) Client Support

Router discovery provides an improved method of configuring and detecting default gateways. When using DHCP or manual default gateway configuration, there is no way to adjust to network changes. Using router discovery, clients dynamically discover routers and can switch to backup routers if a network failure or administrative change is needed. Router discovery is made up of two types of packets: Router Solicitations sent by hosts, and Router Advertisements sent by routers. Windows NT 4.0 supports router discovery as a host only. Router discovery is turned off by default. To enable: Q223756
