Always activate split horizon RIP broadcasts when routing between fully
connected networks like ethernet. This suppresses the announcing of routes
pointing to the interface through which the broadcast is sent. It's
activated by an extra parameter on the RIP add command. I don't have the
exact syntax at hand.

Hello,
I am using KA9Q (NOS) package as an IP gateway between
two Ethernets, but I am experimenting a routing problem.
This is the scene :
KA9Q IP/X25
Sun Sun PC Sun-----------> world
| | | | |
-------------- ---------------
138.82.2 139.82.1
I have defined a default route in the configuration file, so
all the hosts on the 139.82.2 side can reach the world. But,
the problem is that the KA9Q gateway sends this route to
both subnets, changing the default route of the hosts at the
139.82.1 side, pointing it back to the KA9Q gateway !
I don't want to add a route explicitly at every host of
139.82.2 subnet, and want that KA9Q gateway continue to supply
its routing table to both subnets (see the rip add commands below).
Any help/idea/suggestion would be GREAT ! Thanks in advance.
