RE: Routing

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.
