Hi Tanjsree

>From protocol point of view, there is no limit on the number of FIB
entries. If the (synchronized) LSDB has one million entries, each router
would have roughly that many entries.
The limit is a practical one: a large FIB consumes too much memory, or has
an index so large that line speed forwarding is no longer achievable. This
is the motivation of routing scalability such as SNAMP
https://named-data.net/publications/snamp-ndn-scalability/ , but it mainly
applies to inter-domain scenario.

Yours, Junxiao
