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 standalo nes.

Each carrier must be on a separate subnet but, as in the previous scenario, the

carrier-remote combination can share a common subnet. Once aga in, 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.
