How to change route priority in ospf?

Question

Computer networks

Hello, the scheme is given, I won’t go into details, I’ll just say that for the sales21 workstation, the db1 host is available via two routes. All routers are configured with ospf, all networks are added to area 0. It is assumed that the bandwidth for the first route will be 10 Mb/s, and for the second route 2 Mb/s. I have already specified bandwidth 10000 and 2000 in the interface settings. How else can I tell Router2 to only use the first route, on the link with the 5501R1 alive?

Answer 1

You can manipulate the path priority with the cost parameter. You need the total cost on route 1 to be less than 2.
In broadcast mode, cost is set on interfaces.
If all routers are under your control, then the easiest way is to set the RU5501R1 interface towards DB1 cost less. than on a similar interface RU5501R2.
