CDP across frame relay 1

[TNGPicard]

Is CDP supposed to work across a frame relay network? I have checked my router configs for no cdp run globally and no cdp enable on both the ethernet and serial interfaces yet on my host router I see no CDP neighbors. Its not critical to me to have but would be nice for troubleshooting when remote sites call and say they're down.

Yes---it's a layer 2 protocol.

Follow up question in that regard, is it the same for lldp as well? I don't recall if Cisco routers do lldp or not.

As far as I know, LLDP is not vendor specific, and it is also a layer 2 protocol. Cisco does support it---it's just that its own flavor is CDP.
