some practice questions revolving around ospf⌗
q1: router-id⌗
what does router router1 use as its ospf router-id?
the answer is: the router-id is 172.16.15.10, the loopbacks address.
the reason is: the router-id gets set to the loopback address if it is manually set. if there is no loopback address created, it will take the highest ip address and use that instead.
