GX450 DMNR with router attached

I am attempting to use a GX450 with DMNR as a backup WAN connection for a Cisco router. Documentation on how to achieve this is lacking. The GX450 is advertising the networks that are behind the router via DMNR but they are unreachable.

Hi jmooney,

Could you please provide your DMNR configuration and your network topology?

Please censor your sensitive information such as IP, authentication key…


I got it figured, thanks. I guess I was overthinking where doco says to change Ethernet IP to your DMNR network. I left it at the default (, gave router interface an IP in that network and it connected. All good.
