SPF Tree Calculation

• SPF Trees are paths through the network to any given destination.

• A separate path for each known destination will exist. There are 2 destination types recognised by OSPF:

  • Network
  • Router

• Router destinations are specific for ABR’s and ASBR’s.

• After all the OSPF routers have synchronized their link state databases, each router is responsible for calculating its SPF Tree for each known destination.
