IP Network Addressing Scenarios
Scenario 3
135.18.6.22
135.18.6.34
SUBNET 135.18.6.0
135.18.40.1
F-4
This third scenario (Figure F-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.
