G. IP Network Addressing Scenarios
3160-A2-GB24-10 March 2001
G-5
Local and Remote Carriers – Different Subnets
This third scenario (Figure G-4, Local Carrier Connected to Remote Carriers)
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.
