Dear Keith,
IRDP must be supported from your client.
In case of a router you have to configure your router to act as a client.
(this can be done
on some 12.0.T versions. I am trying to find out in which exactly !)
IRDP I supported from some UNIX OS and I think that some realises from LINUX
is supporting IRDP.
The client is listening to the wire and then when he hears an IRDP
announcement he is
using this gateway as his default gateway.
On the lab you will be asked to configure your routers only to support this
feature and nothing more.
Hope this Helps
Regards
Elias Aggelidis

Subject: Basic IRDP Question
Hi All,
I have a very basic question on how IRDP is supposed to work. The Doco CD
explains clearly enough how to configure this (not much to it) but doesn't
give any examples or clearly explain what the result should be.
Take the following scenario..............
R1, R2 and R3 share the same ethernet segment.....
R1:
Interface ethernet 0
ip address 10.1.1.1 255.0.0.0
ip irdp
ip irdp maxadvertinterval 10
ip irdp minadvertinterval 5
ip irdp preference 150
R2:
Interface ethernet 0
ip address 10.1.1.2 255.0.0.0
ip irdp
ip irdp maxadvertinterval 10
ip irdp minadvertinterval 5
ip irdp preference 100
R3:
Interface ethernet 0
ip address 10.1.1.3 255.0.0.0
What should happen here? Should R3 see a default gateway? Should IP Routing
be disabled on R3, as if using proxy arp?
R3 is seeing the advertisements coming from R1 and R2, but that's all.
I'm probably missing some major point with this. Can anyone explain to me
what's happening here
Also, do the switches support IRDP, so as they can have some redundancy
with regards default gateways?
Thanks,
Keith
