Unit 1: Network Infrastructure
This will allow you to demonstrate your networking skills, knowledge, and abilities, with a focus on enterprise-level switching, routing, and multicast components that support cross-platform (inter)operability and integration with the most recent software-defined technologies.
The OSPF cost measure, which is based on link bandwidth, says that higher bandwidth links are better than lower bandwidth lines. The cost metric needs to be changed so that the fastest method is always selected. This is because not all network interfaces can handle the same amount of traffic.
One way to change it is to configure the OSPF Auto Cost Reference Bandwidth. This is the reference bandwidth that is used to make the OSPF cost measure. The OSPF Auto Cost Reference Bandwidth can be set higher than its usual value of 100 Mbps to make sure that links with more bandwidth are given priority.
Open Shortest Path First (OSPF) uses the reference bandwidth to figure out how much a link costs. This cost is then used to find the quickest way to get to a location. By default, the standard bandwidth is set to 100Mbps. You can change this number, though, with the OSPF Auto Cost Reference Bandwidth setting. This is how you do it:
- Use the router’s command-line interface (CLI).
