There are commons and differences to the time when it comes to configuring an OSPF routing protocol on a router you manage, based on the router's manufacturer. We will take a look at the basic sample of configuring OSPF on Cisco IOS-XE and Juniper's JunOS operation systems.
OSPF on Cisco IOS-XEWith ios-xe we start configuring OSPF by mentioning the numerical value of the:
