in.routed question

[davis]

I am using SunOS 4.1 on Sun3's. I have two questions 
about routed.(1) What does the -g option do. I did'nt
see anything about it in the man pages. (2) How can I
force one host on the network to supply routing 
information even though it is not the router? I already
created a /etc/gateways file and started in.routed with
the -s option but it did not seem to make any difference.
The routing tables on the other Suns did not get updataed
after stopping and restarting in.routed. What am I
missing? Thanks in advance.
