Scenario 3
This third scenario (Figure E-3) shows a local carrier
connected to remote carriers that have remote standalones.
Each carrier must be on a separate subnet but, as in the
previous scenario, the carrier-remote combination can
share a common subnet. Once again, the subnet mask is
FF.FF.FF.00 for all devices. A static route must be set up
in the NMS host for each subnet: 135.18.4.0, 135.18.6.0,
135.18.20.0.
