Non-Connected Subnets with ISR and Verizon MPN/DMNR
Non-Connected Subnets – Configuration for IOS Releases 15.5(2)T and Later
In prior IOS releases, ISRs only supported advertising of downstream subnets to the MPN by defining the interfaces
whose subnets are to be registered. Starting with 15.5(2)T a new command under the “IP Mobile Router” stanza
allows for advertising/registering subnets that are not directly connected to the ISR (non-connected-network). This
method is recommended for typical deployments. Alternative configurations are also included after the
recommended method, in case the current IOS release in use is not yet 15.5(2)T, for example 15.4(3)M2.

To support non-connected subnets, add those subnets to the configuration as shown below in red.
