rerouting an IP Address to another

Admins,

In a conversation with SAP they advised me to use static routing to redirect
calls from an IP address to another in order to route the call through
another interface.

Example:
Host A IP address: a.b.c.d netmask 255.255.0.0 Ethernet card tu0
Host A IP address: e.f.g.h netmask 255.255.255.0 FDDI card fta0
Host B IP address s.t.u.v netmask 255.255.0.0 Ehternet card tu0
Host B IP address w.x.y.z netmask 255.255.255.0 FDDI fta0

Host A and B are on the same subnet for the Ethernet interface and on a
private FDDI lan for the ftao interface. The FDDI lan is isolated for all
other nets.
I would like box A and B to declare thier Ethernet address in ARP. So that
they resolve for other boxes as Ethernet. This is true also for Box B, I
would like for it to resolve the IP address for box A as a.b.c.d but when
it uses the address a.b.c.d it really uses e.f.g.h.

I made an entry in the /etc/hosts for Host A

Host A a.b.c.d

so it resolves to a.b.c.d to its name.

I added the static route on Host B
route add -all -host a.b.c.d e.f.g.h

I then used traceroute...It listed one hop...as a.b.c.d...Did it fail to
route through e.f.g.h???
