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
