In my network i have router with 3 outgoing interfaces.
1 - directly connected to backbone, 14 neighbors, bad wifi link
2 - has 1 hope to backbone, 1 neighbor, good wifi + optics
3 - has 2 hopes before backbone 1 neighbor, # wifi links
I want to pass traffic on the second link coz of its quality which is much better then link #1.
I'm changing costs of ospf interfaces , even tried to rise priority of interface.
But still ether1 has state "DR other", and all traffic passed to it.
Other 2 interfaces have "backup" state
ether1 - cost 20, priority 1
ether2 - cost 10, priority 10
ether3 - cost 30, priority 1
