SUMMARY: STEP 1: Problem using 1 Gb ethernet card between 2 SunFire

Bonjour,

~~~~~~~~~~~~~~~~~~~ Thanks ~~~~~~~~~~~~~~~~~~~
First, thanks to: Benoit Audet, Jason Heiss, Martin Hepwort, Tim Chipman.

~~~~~~~~~~~~~~~~~~~ My question ~~~~~~~~~~~~~~~~~~~
I have resolved PARTIALLY my problem. Now, host "mega" use the Gb
ethernet card to communicate with host "watt".

What I want to do next is to access any host on the "110" network from
any host on the "100" network, using by the 1 Gb ethernet card!!!

Presently if I traceroute from "mega" a host on the other network, it
use the long old way (it do not pass by the Gb ethernet card). 

I tried to add routes  on mega and watt without success...
  > mega# traceroute watt
  > traceroute: Warning: Multiple interfaces found; using xxx.xxx.100.8 @ eri0
  > traceroute to watt (xxx.xxx.110.8), 30 hops max, 40 byte packets
  >  1  cisco1 (xxx.xxx.100.97)  1.484 ms  3.349 ms  1.430 ms

  >  3  10.1.125.210 (10.1.125.210)  41.815 ms  31.808 ms  24.640 ms
  >  4  watt (xxx.xxx.110.8)  30.559 ms  28.728 ms  68.268 ms
  > mega# traceroute watt-ge
  > traceroute: Warning: Multiple interfaces found; using 192.168.1.8 @ ge0
  > traceroute to watt-ge (192.168.1.9), 30 hops max, 40 byte packets
  >  1  watt-ge (192.168.1.9)  0.273 ms  0.128 ms  0.156 ms
  > mega# 

Can you help me? Of course, I will summarize.

~~~~~~~~~~~~~~~~~~~ My partial summary ~~~~~~~~~~~~~~~~~~~
What I do with your help:

1- add the folowing entries in /etc/hosts on the 2 SunFires
> # Private network
> # ---------------
> 192.168.1.8     mega-ge
> 192.168.1.9     watt-ge

2- On those SunFires add the file /etc/hostname.ge0 with:
> mega# cat /etc/hostname.ge0
> mega-ge
> watt# cat /etc/hostname.ge0
> watt-ge

3- Start the card on each SunFire:
> mega# ifconfig ge0 plumb
> mega# ifconfig ge0 up
> mega# ifconfig ge0 inet 192.168.1.8 netmask 255.255.255.0 broadcast + up
> watt# ifconfig ge0 plumb
> watt# ifconfig ge0 up
> watt# ifconfig ge0 inet 192.168.1.9 netmask 255.255.255.0 broadcast + up

And now the 1 Gb ethernet card is working, BUT between those 2 hosts ONLY.

Q> ~~~~~~~~~~~~~~~~~~~ My original question ~~~~~~~~~~~~~~~~~~~
Q> I have a problem configuring my network.
Q> 
Q> I have two hosts "mega" and "watt". Each host is  a  SunFire-V880
Q> with  two ethernets cards each. One card is an "eri0", the second
Q> card is "ge0".  The "ge0" card is not yet configured: this is  my
Q> question.
Q> 
Q> Each host run Solaris 9 s9_58shwpl3 SPARC (MU1 applied).
Q> 
Q> Host "mega" is on network xxx.xxx.100.
Q> Host "watt" is on network xxx.xxx.110.
Q> 
Q> The networks are working BUT, I want to inter-connect  those  two
Q> hosts with  the 1 Gb ethernet "ge0" card (optical).  So I want to
Q> use the 1Gb card to connect togheter those two hosts and  by  the
Q> way those two networks too.
Q> 
Q> So, I plug an optical fiber between those  two  hosts.  The  send
Q> optico-cable  is already plugged in the received end and the same
Q> thing apply on the other cable.
Q> 
Q> Can you help me configuring thoses interfaces (ge0)?
Q> 
Q> On mega:
Q> 	hostname.eri0:	mega	# Working at 10 Mb on network xxx.xxx.100
Q> 	hostname6.eri0:	<empty>
Q> 	hostname6.ge0:	<empty>
Q> On watt:
Q> 	hostname.eri0:	watt	# Working at 10 Mb on network xxx.xxx.110
Q> 	hostname6.eri0:	<empty>
Q> 	hostname6.ge0:	<empty>
Q> 
Q> What did I must put on the files: /etc/hostname.ge0 /etc/hosts... 
Q> on each hosts??? How to configure the routes ???
Q> 
Q> I will, of course, summarize.
