Hi Mathew,
To Test this
Try to configure something like =R1= Lo-R6 = =R3 =R2=
If the diagram came mess up, r1,r2,r3 are in the same vlan, r1, r2, r6 are in other vlan.
At R1 enable irdp, also at R2 enable irdp.
Set the higher preference for the router you what to set as default Gateway Enable any IGP between R6 and R1 and R2, Redistriburte the R1,R2 Connected interfaces, so R6 could reach that network At R3 point a static Route to the fas0/0 to proxy-arp for any destination
To test this Sh down the inte sitting with R3 Clear arp at R3 And try again
This is what I saw labbing this today, with your requirement. I think that it could be a combination of Proxy-Arp at the router acting as default-gateway. I have not test the preferences of outgoing, so please excuse me if I’m wrong.
Saludos, Victor.-

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
