If you have a look at this MS Technet article it explains a little more
about IRDP. The client needs to support ICMP based router discovery so it is
not absolutely necessary to have a gateway configured if your client
supports IRDP. This is a client IP stack based way of discovering the
gateways that may be present on their LAN. The router obviously needs to
support it and priority would be the way of controlling the way that traffic
flows before a failure, in other words the way that you want traffic to
flow.

Please correct or add to my comments if I am way off base.
Cheers Darryl.

Subject: RE: IRDP preference question
Hi guys,
I guess IRDP only works if I have all the default gateways which are
advertised by the router interfaces configured on the host ? If I only
configure one default gateway on the host, there is no way the host can
dynamically choose another gateway if that is advertised by the router ?
Example:
Host IP Address: 192.168.17.3
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.17.1
Now let4s say E0 on R1 has IP address 192.168.17.1 that would be the default
gateway for the host. What if I give E0 on R2 IP address 192.168.17.2 and
configure IRDP on that interface with a higher priority than E0 on R1 ?
Since the host only has one default gateway configured, would it pick the
gateway on R2 ?
Thanks for clarifying.
Regards,
Georg
