Re: Routing

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

Name is known. That is not the issue. The issue is the AS400's keep trying
the failed route and do not switch to the alternate route.

Hi Chris,

sounds like a DNS problem, or, more generally speaking, like a name resolution
problem. How do the machines "find" each other by name ? through DNS, hosts files
or by ip-address ? If, for instance, the name of "AS400-1" is still resolving
to the inactive/defunct interface, then you will watch excatly the behaviour
you described below. Having routes setup properly is the one side of the medal.
setting up DNS to support multi-homed hosts is the other. Both work hand in hand,
if setup properly, DNS "round robin" algorhythm will "switch over" to the
active interface after a short time.
