Which of the following is not true in regards to route
summarization?
A. It increases the size of the routing table
B. It increases the complexity of the network
C. IP networks must be contiguous to be safely summarized
D. Routing tables must have the capacity to support
classless routing
Answer / guest
Answer: A
Route summarization DECREASES the size of the routing table
by combining multiple routing table entries into single
routing entry. The complexity of the network is increased
because you have to deal with contiguous addressing, parts
of the summary becoming disjoint, if more specific routes
leak out on another path the longest subnet match will drive
traffic there.
