I like the numbering. :)
1. it's simply an announcing architecture. The "Hi, I'm a Router"
approach.
2. Sort of. Clients can hear multiple gateways all at once. So they have
a selection to make unlike HSRP/VRRP/GLBP which makes the selection for
them.
2. It's part of their programming. Windows will always pause to listen for
this during bootup, even if a DHCP gateway is found. Granted, it will
ignore anything learned, but listens nonetheless. Go figure. Linux I'm not
sure about, though I assume it will listen to the announcements as well.

Hi Group,
When we configure a CISCO router to announce itself as a Default gateway via
IRDP, I think all we need is to configure "ip irdp"
(minimum) under the LAN interface. Here I believe router acts as a server.
1. Is the IRDP client/server architecture?
2. Is this a dynamic way to tell the clients compared to static ways like
HSRP/VVRP?
2. How do the Clients (Windows, Linux etc) learn this gateway?
Thanks
Mathew
