The parameters of the generated default route are determined by the default-route-advertise [ always | cost cost | type type | tag tag | route-policy route-policy-name ]* command. The preferences of parameters of the default route configured in a route-policy are higher than those of ...
In this case, the router chooses the path with the lowest cost (or metric) to the destination. Each routing process calculates its cost differently; the costs may need to be manipulated to achieve load balancing. OSPF performs load balancing automatically. If OSPF finds that it can reach a ...
the default cost assigned to a Fast Ethernet interface is 10. This means that OSPF will consider a Fast Ethernet link with a cost of 10 as the reference point for calculating the cost of other routes. Any link with a higher bandwidth will have a lower cost in OSPF, ...

The cost of interfaces with link speeds lower than 100Gbps is higher. To avoid routing loops, set the bandwidth to a consistent value across all OSPF routers.The following example commands configure the auto-cost reference bandwidth for 90Gbps link speed:...
The cost of interfaces with link speeds lower than 100Gbps is higher. To avoid routing loops, set the bandwidth to a consistent value across all OSPF routers. The following example commands configure the auto-cost reference bandwidth for 90Gbps link speed: cumulus@switch:~$ sudo vtys...
Calculating the OSPF Cost From the previous section, we know each link has a cost. This cost exclusively rely on the bandwidth of the link: the higher the bandwidth, the lower the cost. Specifically, OSPF has the concept ofreference bandwidth. This is the bandwidth for which you want to ...
routers. It represents the overall expense of sending data packets across a particular link or interface. In OSPF, the cost is inversely proportional to the bandwidth of the link. In other words, links with higher bandwidth have lower costs, indicating they are more preferable for routing ...
The method for configuring cost values differs between the OSPF and RIP protocols. Configure the cost values of OSPF links to ensure that preferred routes to destinations have a lower cost than less preferable routes. The less preferable routes, with the higher cost, are not used except upon fa...
