OSPF is configured using default classful addressing. With all routersand interfaces operational,
how many networks will be in the routing table of R1 that are indicated to be learned by OSPF?

R1 is configured with the default configurationof OSPF.From the following list of IP addresses
configured on R1, which address will the OSPF process select as the routerID?
