Web-OSPF defines the cost metric as "a single dimensionless metric" that is "configurable by a system administrator" and is associated with the output side of each router interface.-The cost of an interface defaults to 100,000,000 divided by the bandwidth for the interface on a Cisco router. It can be manually configured. WebNov 17, 2024 · The OSPF metric for a route is the sum of the interface costs for all outgoing interfaces in the route.

WebOSPF Metric Calculation As OSPF is a Link State routing protocol, the router will learn about all the destinations in its area, the links to get there, and their cost. The router will select routes based on the lowest cost to get to the destination, and that's the route that will make it into the routing table. WebOSPF maintains a database of locally derived and learned networks. If multiple OSPF paths to remote networks exist, OSPF chooses a path based on the lowest calculated cost or metric. The path cost to a remote network is based on the total calculated reference bandwidth divided by interface bandwidth. WebOSPF uses the following formula to calculate the path cost when interface bandwidth is available: OSPF path cost = ((auto-cost × reference-bandwidth + interface bandwidth) -1) / … campingplätze tessin mit hund
