redundancy from ibm os/390 tcpip to dual routers

[jmay]

I have 2 routers that have single escon connections to the same mainframe tcpip stack (os/390 2.9). What is the best way to provide failover from mainframe should one router fail. this involves mainly ibm tcpip configuration and would prefer to do without routing on mainframe and have to pass routing updates between mainframe and routers. Has anybody set up this scenario?

Have you looked at using VIPA .

I have looked at VIPA but was hoping there is something that does not require routing updates sent from mainframe and also the routed setup. We are running IBMs TCPIP not Cisco S/390.
