Here's the setup:

Cisco 7204 router connect to a ME3400 via 100Mb. M3400 has a 1000Mb fiber connection to a MUX. The MUX, via SONET transport, has 100Mb connection to remote switch, a 6509.

Remote switch can see the ME3400 via cdp. ME3400 can't see remote switch via cdp. Remote switch see's the ME3400's arp entries, although no ping replies are received. The ME3400 doesn't have arp entires for the remote switch.

Communication seems to be only one way. The transport facility tests good. Any thoughts?

How is the port on the ME3400 setup? UNI or NNI? uplinks to your equipment should be NNI's. To customers, you want them as a UNI. If you change the port to NNI does it work?

interface GigabitEthernet0/1

port-type nni
