Cost = reference Mbps / interface Mbps (minimum 1) with IOS command output.
OSPF cost = reference Mbps / interface Mbps (minimum 1).
OSPF cost: 1
Link (1000 Mbps) exceeds reference (100 Mbps) — cost floors at 1. Increase auto-cost reference-bandwidth so 1G/10G/100G paths have distinct costs.
auto-cost reference-bandwidth 10000
OSPF Cost Calculator helps you cost = reference mbps / interface mbps (minimum 1) with ios command output. It is commonly used by network admins, IT support teams, ops engineers for ospf cost calculator, auto-cost reference-bandwidth, ospf metric.
Recommends raising reference bandwidth when high-speed links all cost 1.
