10
www.ciscopress.com Copyright 2003 OSPF Overview OSPF is becoming the preferred IGP protocol when compared with RIPv1 and RIPv2 because it is scalable.

www.ciscopress.com Copyright 2003 Configuring OSPF Loopback Address and Router Priority
20
www.ciscopress.com Copyright 2003 Configuring Router Priority The priorities can be set to any value from 0 to 255. A value of 0 prevents that router from being elected. A router with the highest OSPF priority will win the election for DR.
