Don't mess with the Linux broadcast address.  It is selected automatically
(and correctly) based on the subnet mask you provided to it.  You *do*
need to add a default route to the Linuxen pointing to VM TCP/IP.  VM's
default route is the Cisco router.  You know the following information:
- z/VM TCPIP on ethernet LAN => 10.25.25.155
- Linux01 on guest LAN => 10.22.25.10
- Linux02 on guest LAN => 10.22.25.11
- Cisco Router => 10.25.1.1

I extracted the following information from your PROFILE TCPIP, but I have
no way of knowing if these are the values you intended (only you know the
answer to that):
- Subnet mask of ethernet LAN:  255.255.0.0
- Subnet mask of guest LAN: 255.255.255.0

There is one missing piece of information:
- z/VM TCPIP on guest LAN

I'm going to make up an address: 10.22.25.1

Given all of the above, you would code:
HOME
   10.25.25.155  ETH0
   10.22.25.1    VHIP1

GATEWAY
   10       =     ETH0  1500  0.255.0.0    0.25.0.0
   10       =     VHIP1 1500  0.255.255.0  0.22.25.0
default 10.25.1.1 ETH0  1500  0

In each Linux, specify a default gateway of 10.22.25.1.  The Cisco router
will have to be told to route 10.22.25.0/24 through 10.25.25.155.
