[SunHELP] About route question (very interesting topic)

[John Lee]

Hi Fogg,

Thanks for your input.

Actually, I don't think my NT machine is broken because all our more than
200 NT machines have the same case. This is an interesting thing. Let me
decribe it in detail.

On one subnet 200.10.2.x(mask is 255.255.255.0), If I set one NT machine's
default gateway as its IP(for example: 200.10.2.25), then run tracert
command, the result will be as below:
-----------------------------------------
c:>tracert 200.2.1.27
Tracing route to 200.2.1.27 over a maximum of 30 hops
1    <10ms    <10ms    <10ms    200.3.1.254
2    <10ms    <10ms    <10ms    200.2.1.27
-----------------------------------------
If I run traceroute command  on a solaris machine with IP=200.10.2.26, the
result will be:
-----------------------------------------
%traceroute 200.2.1.27
traceroute to 200.2.1.27 (200.2.1.27), 30 hops max, 40 byte packets
1    200.10.2.254(200.10.2.254)     0.397 ms  0.361 ms  0.322 ms
2    200.4.3.254(200.4.3.254) 0.514 ms *  0.499 ms
3    200.2.1.27(200.2.1.27)     4.116 ms *  3.323 ms
----------------------------------------

>From above, We can see NT machine's IP traffic route is different with
Solaris machine. What I want to do is let Solaris machine go through the
same route as NT machine. I don't know how to do. It seems that NT machine
is VLAN aware, but Solaris isn't.

By the way, Many of my colleagues think it is strange thing. But it is true
and I have tested on serveral subnets. Our network equiment include Cisco
and CableTron.

I think this is an interesting topic worth of discussing. I don't know if I
need install the third-party software on Solaris so that it can be VLAN
aware.

Thanks for all your input !

Best Regards
John

Your NT machine is actually broken. Its default gateway should be the
gateway for the VLAN router. MS networking uses broadcast netbios
annoucements to "find" each other and build the network browse lists.
Because of this, the brokeness isn't apparent.
