Not sure why you thought this was required.
If this is RFC 1256, then it is used in an HA
config to find other routers.

Non of my Cisco, or firewalls (PIX and Check point) have this turned on.
For us we use VIPs and VRRP but do not use ICMP discovery.


Maybe we should look at it.


That's good to know. I was assuming ICMP Router Discovery was the only way routes are dynamically managed. Thanks.




Before I travel too far down this tangent (and drag you all with me), let me go back to the simple goal I'm trying to achieve:

My application simply needs to know the addresses of **all** of the routers attached to the computer's various networking interfaces.

For example, on my ibook, I have an airport connection to one router (192.168.0.250) and a cat5 connection to another router (192.168.1.250).

When I open system prefs, click "Network", and look at the TCP/IP section of Airport, I see "Router: 192.168.0.250".

When I look at the TCP/IP section for Built-in Ethernet, I see "Router: 192.168.1.250".


What is the simplest way to get that exact same information?

That's all I want.
