Answer: A
Using route summarization, these eight networks can be
summarized into one larger network and then advertised. You
could have these routes advertised individually as
192.108.168.0/24, 192.108.169.0/24, etc. or summarize then
all as 192.108.168.0/21. This is one-eighth the size of the
original route table. This can save a lot of memory and
processing power, especially when you?re talking about
hundreds or thousands of routes. The three factors that
confirm when it?s beneficial to use route summarization are:
1. The IP networks must be contiguous (for example,
199.42.168.0, 199.42.169.0, 199.42.170.0, etc.). Networks
that aren?t contiguous cannot be summarized safely into a
single statement.
2. The routing tables must support classless routing.
3. The routing protocols must support both prefix length and
subnet information along with the IP address.
