ISP network engineering and technical consulting services by TurnkeyISP

Define how access networks reach your aggregation and core routers. Review routing boundaries, address plans, service dependencies, and the points where an equipment or transport failure could affect multiple subscribers.

Map how traffic moves between access, aggregation, and upstream connections. Document switch roles, uplinks, and the management path so the proposed topology can be reviewed alongside your current equipment and operating procedures.

Review BGP at your network edge and OSPF within the network against the routes and reachability you intend to provide. Establish the policies, testing, and approvals required before changes are made to a production router.

Discuss which services need separation across your transport network and whether MPLS or VPLS fits that design. Record service boundaries and dependencies before selecting the configuration or migration approach.

Separate subscriber, infrastructure, and management traffic according to your network design. Agree the VLAN plan, access boundaries, and documentation that local staff will use to maintain it.

Identify equipment, transport, and upstream dependencies that share a failure point. Define the expected alternate path and the checks needed to test failover during an approved maintenance window.

Plan IPv6 allocation, routing, and subscriber delivery alongside the systems already in use. Include management access, operational documentation, and a controlled rollout rather than treating IPv6 as a single router setting.

Record the design decisions, change plan, validation checks, and responsibilities for ongoing operation. NOC monitoring and outage coordination can be scoped separately. For tower, backhaul, and subscriber-access work, explore WISP network engineering.
