linux 2.4 routing algorithm?

[Kristen Carlson <kristenc@xxxxxxxxxx>]

Hello,
I'm trying to understand the routing algorithm for linux 2.4.  I thought
it would use a longest prefix match due to some documentation I had googled,
but the code in route.c looks like a hash.  I probably just don't understand
how lpm would be coded in practice.  Am I looking in the right place?  Can
someone give me a clue about how this works?

Thanks,
Kristen
