That depends.... if by "summarize" they mean filter prefixes
longer than say /22, or otherwise...: discard extraneous prefixes
from networks that were allocated a /16 network but chose to
deaggregate and advertise every /24 ------ choosing to accept only
the /16 advertisement instead of installing these extra /24 routes in
the FIB, then there are plenty of entries to "summarize" away.
