Re: Routing

[Philipp Rusch <philipp.rusch@xxxxxxxxxxxx>]

Sorry, I missed the point: the gateway has different addresses, not the
AS400 itself, I misread this !
So, your routing entries point to one and the same network but you have
two different Gateways to get there.
I would expect to handle to routers all the failover automatically, but
there is a parameter in TCPIP configs about "Dead Gateway detection".
CHGTCPA ipdeadgate (*yes 2), where the 2 means check every 2 seconds
You should give it a try.

HTH now, Philipp
