Routing problem

Sorry this is long winded, but I'm trying to make a brief as possible.

When I have the 2600 in place I can access 10.30.81.1 from 10.30.80.1 no problems. Been using this config for year at several sites.

When I have the 3560 in place I can not get to 10.30.81.1 from

10.30.80.1 at all... arp shows incomplete..

Thanks much for reading at least this far:)

Details below =========================================== I know this is a bit of an unusual config, but it's currently working on a Cisco 2600 router, however I can not get it to work on a Cisco

3560 l3 switch. Here's the config on the cisco: ===============2600================= in f0/0 ip address 10.30.80.1 255.255.255.0 ip address 10.30.81.205 255.255.0 secondary

ip route 10.30.81.1 255.255.255.255 10.30.80.2 =================================== ===============3560================ The 3560 is slightly diff because it's a switch, in vlan1 ip address 10.30.80.1 255.255.255.0 ip address 10.30.81.205 255.255.0 secondary

ip route 10.30.81.1 255.255.255.255 10.30.80.2 ================================== THere is an engage IP box @ 10.30.82.2 that passes packets to

10.30.81.1 IP_Device. Line diagram like so... ROUTER=====ENGAGE======IP_DEVICE 10.30.80.1 10.30.80.2 10.30.81.1

When I have the 2600 in place I can access 10.30.81.1 no problems. Been using this config for year at several sites.

When I have the 3560 in place I can not get to 10.30.81.1 at all... arp show incomplete..

Can someone tell me what the 2600 would work and not the 3560? All else is configured the same with exception of the 3560 is a Vlan interface. I can still ping 10.30.82.2, but just can't seem to get past it to 10.30.81.1

Here's a copy of the config on the 3560:
