Router configuration
We are trying to use a Cisco 2811 to move data from one segment to another. The Fe0/0 port is configured to 192.9.100.194 (Business Side) and the Fe0/1 is set at 152.52.42.194(test side equipment network). All concentrators and equipment are set to a default-gateway of 192.9.100.250 which is a 6509 router. The issue is that the 6509 can see the 192. side of the 2811 but cannot ping the 152 side of the 2811. The route's are correct on the 6509. Is it possible that due to the Fe0/0 being on the same segment that the packets are being dropped by the 6509. Would changing the 2811 192 address to another network IP allow the data from the 152 network to be seen. As it is the 2811 can be pinged but no access is possible to or from the 152 segment by the 6509 (192.9.100.250 ) 6509 route:  IP route vrf PC7118 156.52.42.0 255.255.255.0 255.255.255.0 192.9.100.194 x

Thanks. We'll let you know when a new response is added.

We don’t have enough information to go on…
- what are the netmasks in use
- is there a routing protocol in use here, or using purely statics
- details on statics, or routing protocol being used?

Possibly, you can see the 192. side of the router as it looks like just another device on the network; but hasn’t been set up to do forwarding TO the 152. side; and the 152 side needs to know the way back; although in this scenario with no downstream networks in place (??) that return packets would work IF the downstream lab devices at least had their gateways set to 152.52.42.194.

—————————————

As stated above: we need a bit more info to be 100% accurate.

However, you did not mention
1) if you were using any routing protocols (RIP, OSPF, EIGRP) for routing on the 2811
2) If you have static / return routes on the 2811 back to the 6509

Based solely on what is provided, best place to look is routing on the 2811…

    Do you have VRF config on both, 2811 and 6509? If so, I'd check route leaking first.
