What are two features of the OSPF routing protocol? (Choose two.)
- has an administrative distance of 100used primarily as an EGP
- uses Dijkstra's algorithm to build the SPF tree
- automatically summarizes networks at the classful boundaries
- calculates its metric using bandwidth
Explanation: Characteristics of OSPF include the following:
Interior gateway protocol
Link-state
Classless
Cost metric based on bandwidth
Dijkstra algorithm
Builds topological map
Event-driven updates
Hierarchical design
Requires additional memory, CPU processing, and more initial bandwidth than other protocols
