Ok, here's a real funny one.....

1) There's Company A and Company B

2) Company A has two locations, across the street from each other and they're connected via T1 with a Cisco 3600 in location A1 and a 2600 in A2

3) Company B is not related at all to Company A but they lease space at location A1, we'll call it B1

4) Half of B1 is moving to space being built at A2, we'll call this B2

5) Company B does not want to establish a connection (similar to Company A and their T1) between B1 and B2

6) They would like B2 to use A2's network connection to A1 to get to their own network at B1

7) Company A uses DHCP (10.x.x.x); company B uses static IP (202.202.x.x)

8) A physical cable link (CAT5) has been established between A1 and B1 and the connection worked as intended, allowing access to B1 LAN - meaning, using Company B's static IP information in one of their machines, connected to Company A's LAN, we could get to their LAN through Company A's network; connecting the two simply by a switch to switch cable (offices across the hall from each other, A1 to B1)

9) If A2 has connectivity to A1 and A1 also has physical and proven connectivity to B1, why am I not getting to B1 from A2 ??

10) Is it possible to accomplish this? (which is the actual and ultimate goal of this project)

11) What would you recommend? - I have thought about:

a) static routes

b) modifying DHCP or WINS tables

c) VPN, bypassing A1 completely

d) PBR


Re: Ok, here's a real funny one.....

The easiest method would be to insert static routes at all company A's routers which accomodate company B's network.

Start with routing basics:
