Why Build Link State Flooding Domain Boundaries in Large-Scale Networks

Multiple Choice

Why build link state flooding domain boundaries in large-scale networks running OSPF or IS-IS? (Choose two.)

A) Flooding domain borders block the transmission of external routing information in the network, which improves scaling and convergence times.
B) Network administrators can quickly find specific destinations when detailed link state information is sorted by flooding domain in the link state database.
C) Doing so limits the extent of SPF and allows the use of PRC for some best path calculations.
D) Doing so provides logical break points at which to troubleshoot individual parts of the network, rather than trying to troubleshoot the whole network at once.
