HI,

I have Cisco 1750 Routerz & Cisco 6509 sup2 with MSFC, below are my question, kindly suggest me what i should, thankz in advance.

LOCATION X

-----------

Router A IP address 170.1.32.1

WinNT PC IP address 170.1.32.2

LOCATION Y

----------

Router B IP address 170.1.96.1

LINUX PC IP address 170.1.96.2

2nd NIC IP address 10.201.1.2(connected to 6509)

gateway 10.201.1.252

Note: PC having 2 Network Interface Cards

LOCATION Z

----------

Windows 2000 PC IP address 10.205.1.100(connected to 6509)

gateway 10.205.1.252

Note: 170.1.32.2 can reach 170.1.96.2 (connected via 2Mbps Leased Line)

10.201.1.2 can reach 10.205.1.100(VLAN server is the MSFC)

now i wanted 170.1.32.2 should reach 10.205.1.100, how do i do this?

Create a VLAN on 6509 for the subnet 170.1.96.0. Assign at least 2 ports for this VLAN. Then connect Router B and LINUX PC to these 2 ports.

Create the corresponding VLAN interface with an IP address, say 170.1.96.3. Then add a static route in 6509 whose destination network is 170.1.32.0/24, next hop is 170.1.96.1.

Then add a static route in Router A, whose destination network is 10.205.1.0/24, next hop is Router B WAN IP address (you should have another subnet for the point-to-point leased line between Router A and B).

Or if your LINUX PC is actually a firewall, then enable NAT so everything in 10.205.1.0 will be translated to 170.1.96.x.

Or you can enable routing on LINUX PC and add the static routes...

Well, seems to be an intresting one. Does your linux box has routing capability. I know Windows 2K server and Xp has this capability. It can work in that way.

I have thought of a work around too, I am not sure that will work as I have not tested. See the below steps:

1. Create a new Vlan (170.x) on 6509,Connect the router B port 170.1.96.1 to one of the port on the same Vlan.

2. Connect the linux box NIC with IP 170.1.96.2 to the same Vlan (170 .x)

3.Now you have the other NIC with IP (10.x) in a separte vlan which is already reaching 10.205.1.100.

4. Now on MSFC create the respective L3 VLAN interfaces and use either a routing protocol or static routes to work it out.

I have not tried it, lets hope it works.

HTH,
