Ip Irdp - Dell Networking 2024 Reference Manual

Router Discovery Protocol
Commands
Dell Networking N3000/N4000 Series Switches
Routers can be configured to periodically send router discovery messages to
announce their presence to locally attached hosts. The router discovery
message advertises one or more IP addresses on the router that hosts can use
as their default gateway. Hosts can send a router solicitation message asking
any router that receives the message to immediately send a router
advertisement, so that the host does not have to wait for the next periodic
message.
Router discovery enables hosts to select from among multiple default
gateways and switch to a different default gateway if an initially designated
gateway goes down.
